YASUR

As of the 1st of August, mainly from reports from colleague, John Seach of Australia, he reports that Yasur volcano, in southern Vanuatu continues to be one of the world's most active volcanoes. The volcano has erupted many times per hour for at least 800 years. Yasur has been called the "Lighthouse of the Pacific" because of the regular Strombolian eruptions visible from sea. Warning: Approaching the active crater at Yasur volcano is dangerous at any time! Observers are at risk from projectiles, toxic gas and avalanches.

Yasur, the best-known and most frequently visited of the Vanuatu volcanoes, has been in more-or-less continuous strombolian and vulcanian activity since Captain Cook observed ash eruptions in 1774. Yasur, located at the SE tip of Tanna Island, is a mostly unvegetated 361-m-high pyroclastic cone with a nearly circular, 400-m-wide summit crater. Yasur is largely contained within the small Yenkahe caldera and is the youngest of a group of Holocene volcanic centres constructed over the down-dropped NE flank of the Pleistocene Tukosmeru volcano. Active tectonism along the Yenkahe horst accompanying eruptions of Yasur has raised Port Resolution harbour more than 20 m during the past century.

The Current Colour Code for Yasur is ALERT LEVEL 3

STROMBOLI

As of the 2nd of August, the Instituto Nazionale di Geofisica e Vulcanologia - Sezione di Catania has reported that as Andrea Ercolani reports from Stromboli, the "normal" Strombolian activity seems to be returning to the summit craters since early July. After the effusive eruption which ended on 4th of April this year and a powerful vent-clearing explosion on 15 March, there have been deep-seated explosions ejecting black ash clouds since May. In July, these have beomce more regular and it seems that the magma level inside the vents has been rising and there could soon be visible lava ejections again. Access to the summit is still restricted and visitors may only climb up to 400m elevation accompanied by an authorised mountain guide, but it is being discussed wether new rules to allow access to the summit will be established. This will be communicated here as soon as it happens. Stromboli is a continuously active stratovolcano. The summit is at 924 m.a.s.l. However, the base of the volcano is between 1500 and 2000 m below the sea. The surface area of the island is only 12.6 square kilometres.

Spectacular incandescent nighttime explosions at Stromboli volcano have long attracted visitors to the "Lighthouse of the Mediterranean." Stromboli, the NE-most of the Aeolian Islands, has lent its name to the frequent mild explosive activity that has characterised its eruptions throughout much of historical time. The small, 924-m-high island of Stromboli is the emergent summit of a volcano that grew in two main eruptive cycles, the last of which formed the western portion of the island. The Neostromboli eruptive period from about 13,000 to 5000 years ago was followed by formation of the modern Stromboli edifice. The active summit vents are located at the head of the Sciara del Fuoco, a prominent horseshoe-shaped scarp formed about 5000 years ago as a result of the most recent of a series of slope failures that extend to below sea level. The modern volcano has been constructed within this scarp, which funnels pyroclastic ejecta and lava flows to the NW. Essentially continuous mild strombolian explosions, sometimes accompanied by lava flows, have been recorded at Stromboli for more than a millennium.

Mt. EREBUS

As of the 1st of August, the Mt. Erebus Volcano Observatory (MEVO) reports that Mt. Erebus has frequent Strombolian eruptions. Infrequent ash eruptions. Rare lava flows confined to inner crater. Notable features are: Persistent convecting phonolite lava lake. Persistent low-level eruptive activity. One of Earth's few long-lived lava lakes. Most active volcano in Antarctica. Lavas and bombs contain large (<10 cm) phenocrysts (crystals) of anorthoclase feldspar.

Mt. Erebus, Ross Island, Antarctica is the worldís southern-most active volcano. Discovered in 1841 by James Ross, it is one of only a very few volcanoes in the world with a long-lived (decades or more) lava lake. Scientific research, sponsored by the U.S. National Science Foundation (NSF) since began the early 1970ís had included basic study of the petrology and geophysics of the volcano, the eruptive history, activity and degassing behavior of the lava lake, and the overall impact of the volcano on the Antarctica and global environment.

Research on Mt. Erebus has been primarily conducted by scientists in the Department of Earth and Environmental Science and the Bureau of Geology and Mineral resources at the New Mexico Institute of Mining and Technology. Each austral summer, a group of scientists and students ascend the volcano to live and work for several weeks (early December to early January). Current research consists of 1) continued monitoring of the SO2 flux from the lava lake, 2) measuring the CO2 emissions from the lava lake and summit, 3) geochronology of the summit and flank lava flows, 4) continued monitoring of the seismic and seismoacoustic activity of the volcano through the use of a network of highly-sensitive broad-band seismometers, 5) establishing a GPS base network to monitor the short- and long-term deformation of the volcano.

And that doesn't include all the underwater volcanoes that they have just recently found. There are 1,000s of them and many of them are currently active. Such activity is bound to increase the temperatures of the oceans.

I'm going to guess that Al Gore has been loose in the ocean also. There's global warming wherever that guy goes. I think that Al Gore should be locked up for the good of the planet.   Grin

 Ethiopia volcano erupts, 2 missing

Fri Aug 17, 6:33 AM ET

ADDIS ABABA, Ethiopia - A volcano erupted in the remote desert of northern Ethiopia, and two people were missing, the state-run news agency said.

The volcano spewed lava for about two hours Sunday in the Afar region, a spectacular yet barren expanse of volcanoes and ancient salt mines where bandits and rebels operate.

The area is inhabited mostly by nomads.

The eruption was reported to government officials via telegram and they sent a team to investigate, the Ethiopian News Agency reported Wednesday.

The area is one of the hottest and most inhospitable in the world, with an average annual temperature of 95 degrees, although it often gets much hotter.

Alaska's Pavlof Volcano Erupting Molten Lava

Friday , August 17, 2007

AP
ADVERTISEMENT

ANCHORAGE, Alaska —
One of Alaska's most active volcanoes could be working toward a massive eruption that could affect air travel but was not expected to threaten any of the towns in the area, scientists said Thursday.

Satellite images of Pavlof Volcano taken Thursday showed strong thermal readings, consistent with what the Alaska Volcano Observatory is calling a "vigorous eruption of lava" at the volcano about 590 miles southwest of Anchorage on the Alaska Peninsula.

The volcano is below the path of hundreds of daily international flight paths, and an explosive eruption could interrupt those operations, said Steve McNutt, a volcano seismologist with the observatory. Volcanic ash can enter an engine and make it seize up, he said.

The Federal Aviation Administration sent advisories to airlines that might be operating in the area and is monitoring the situation, said spokesman Allen Kenitzer. If there is a severe eruption, flights would have to be diverted, possibly resulting in delays, he said.

McNutt said seismic activity is high at the 8,262-foot volcano, with about one tremor recorded every minute. Lahars — mudslides caused when lava melts snow on the peak — have triggered some seismic activity, as well, he said.

The mudslides took place on the southeast side of the volcano, an area he said is inhabited by few, if any, people. Pavlof is about nine miles from Pavlof Bay, a popular fishing ground, but at the moment it isn't posing an immediate threat, McNutt said.

He said hazards the volcano could present included light ash fall on nearby communities, mud flows, lava flows and hot debris avalanching on the volcano's flanks.

Several small towns are in the area, including King Cove, which is about 35 miles to the southwest with a population of roughly 800, and Cold Bay, nearly 40 miles southwest with a population of about 90. But they're too far to be affected by lava, and McNutt said an eruption probably would coat the towns with no more than a 2- or 3-millimeter-thick blanket of ash.

Josh Gould, co-owner of King Cove grocer John Gould & Sons Co. Inc., said people in town were preparing for the worst while hoping for the best. Sales of basic staples are up, he said, but there's no danger of running out of products like water, bread and milk.

He said that an ash plume was visible from town, but that none was falling on it yet.

Seismic activity was first picked up at the volcano Tuesday. Eyewitnesses aboard a fishing boat in the area Wednesday reported glowing lava on the volcano's southeast flank. Pilots have reported a weak plume of ash drifting 5 miles to the southwest and likely below 20,000 feet.

"What we think we're in for is several months of low-level eruptions punctuated by a few large and explosive events," McNutt said.

Pavlof, which has had about 40 eruptions since record keeping began in the area in the 1760s, is among the most closely monitored volcanoes in the state, with permanent monitoring equipment installed nearby.

Its last eruption was in 1996; that 11-year span is the longest Pavlof has gone without an event, McNutt said. A string of eruptions took place during the 1970s and 1980s.

A series of ash explosions and lava eruptions took place for several months after the last eruption. Ash clouds reached as high as 30,000 feet at the time. During a 1986 eruption, Pavlof spewed ash as high as 49,000 feet.

PAVLOF

As of the 17th of August, the Alaska Volcano Observatory (AVO) has reported that the intensity of earthquake activity at Pavlof Volcano has increased this morning. Satellite images of the volcano overnight and this morning show continuous strong thermal anomalies at Pavlof. Residents of both Cold Bay and Sand Point observed incandescence at the summit. These observations are consistent with vigorous eruption of lava at the surface.

The primary hazard from this eruption is airborne ash. If activity continues to increase in intensity, larger ash clouds that could affect aircraft may be produced. The most immediate ground hazard in the vicinity of the volcano includes light ash fall on nearby communities. Previous historical eruptions from Pavlof caused only a few millimeters (about 1/10th of an inch) of ash to fall on King Cove, Nelson Lagoon, and Sand Point. Mudflows in drainages from the flanks of the volcano, and lava flows and avalanching of hot debris on the upper reaches of the volcano are also of concern in the uninhabited areas around the volcano. Satellite data and eyewitness observations suggest most of the surface lava activity is occurring on the southeast sector of the steep-sided volcano; this suggests that the Pacific Ocean side of the volcano is at most risk from avalanching hot debris. AVO continues to monitor the activity closely; satellite and seismic data are checked frequently around the clock. AVO is planning the installation of additional monitoring equipment including a web camera.

The most active volcano of the Aleutian arc, Pavlof is a 2519-m-high Holocene stratovolcano that was constructed along a line of vents extending NE from the Emmons Lake caldera. Pavlof and its twin volcano to the NE, 2142-m-high Pavlof Sister, form a dramatic pair of symmetrical, glacier-covered stratovolcanoes that tower above Pavlof and Volcano bays. A third cone, Little Pavolf, is a smaller volcano on the SW flank of Pavlof volcano, near the rim of Emmons Lake caldera. Unlike Pavlof Sister, Pavlof has been frequently active in historical time, typically producing strombolian to vulcanian explosive eruptions from the summit vents and occasional lava flows. The active vents lie near the summit on the north and east sides. The largest historical eruption of Pavlof took place in 1911, at the end of a 5-year-long eruptive episode; a fissure opened on the northern flank of the volcano, ejecting large blocks and issuing lava flows.

Mt. CLEVELAND

As of the 17th of August, the Global Volcanism Network (GVN) via the Alaska Volcano Observatory (AVO) has reported that no activity was observed in partly cloudy satellite views last night. Fog and clouds obscured webcam views. AVO continues to monitor the volcano closely with satellite imagery as weather allows. The lack of a real-time seismic network at Cleveland means that AVO is unable to track local earthquake activity related to volcanic unrest. Short-lived explosions of ash that could exceed 20,000 ft above sea level can occur without warning and may go undetected on satellite imagery.

The symmetrical Mt. Cleveland stratovolcano is situated at the western end of the uninhabited dumbbell-shaped Chuginadak Island in the east-central Aleutians. The 1,730-m-high stratovolcano is the highest of the Islands of Four Mountains group and is one of the most active in the Aleutians. Numerous large lava flows descend its flanks. It is possible that some 18th to 19th century eruptions attributed to Carlisle (a volcano located across the Carlisle Pass Strait to the NW) should be ascribed to Cleveland. In 1944 Cleveland produced the only known fatality from an Aleutian eruption. Recent eruptions from Mt. Cleveland have been characterized by short-lived explosive ash emissions, at times accompanied by lava fountaining and lava flows down the flanks.

UBINAS

As of the 16th of August, INGEMMET reported that based on a Significant Meteorological Information (SIGMET) advisory, the Buenos Aires VAAC reported that an eruption plume from Ubinas rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted SE on 9 August.

A small, 1.4-km-wide caldera cuts the top of Ubinas, Peru's most active volcano, giving it a truncated appearance. Ubinas is the northernmost of three young volcanoes located along a regional structural lineament about 50 km behind the main volcanic front of Perú. The growth and destruction of Ubinas I volcano was followed by construction of Ubinas II volcano beginning in the mid-Pleistocene. The upper slopes of the andesitic-to-rhyolitic Ubinas II stratovolcano are composed primarily of andesitic and trachyandesitic lava flows and steepen to nearly 45 degrees. The steep-walled, 150-m-deep summit caldera contains an ash cone with a 500-m-wide funnel-shaped vent that is 200 m deep. Debris-avalanche deposits from the collapse of the SE flank of Ubinas about 3700 years ago extend 10 km from the volcano. Widespread plinian pumice-fall deposits from Ubinas include one of Holocene age about 1000 years ago. Holocene lava flows are visible on the volcano's flanks, but historical activity, documented since the 16th century, has consisted of intermittent minor-to-moderate explosive eruptions.

HUILA

As of the 15th of August, with respect to the pursuit of the activity of the snow-covered volcano of the Huila, INGEOMINAS, Observatory Vulcanológico and Sismológico de Popayán, informed that in the month of August of 2007 a total of 356 events were registered; of which, 220 events are associate to fracturing of rock, 136 events associated to the fluid movement and transit of and gases within the internal conduits of the volcano, and 18 events that as much contain compound mechanisms of fracture as of transit of fluids.

One stands out that the associated events to fracturing of rock are located so much in the Central Tip as in Eastern and South the flanks of the volcano, the depths oscillated between 1.5 and 7.5 km and with smaller magnitudes of 1.0. A happened earthquake is emphasised within this activity day 11 of August to the 1633hrs local time, which was located to 2 km in south-western direction of the South Tip, its calculated magnitude was of 2.65 and depth of 6 km. Of the previous item it is emphasised that the system continues presenting/displaying low levels of excitation, associated with the internal dynamics of the volcano. INGEOMINAS continues kind to the evolution of the volcanic phenomenon and will inform INTLVRC in an opportune way any changes that can be presented/displayed.

KARYMSKY

As of the 17th of August, the Kamchatkan Volcanic Eruption Response Team (KVERT) has reported that the eruption of the volcano continues. Ash explosions up to 6 km (or 19,700 ft.) ASL are possible at any time. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano. Seismic activity was above background levels all week, 350-600 shallow volcanic earthquakes and a spasmodic volcanic tremor were registered at volcano all days. According to seismic data, possibly ash explosions rose up to 3.0 km (9,850 ft) ASL . According to satellite data, the volcano was obscured by clouds all week.

Karymsky, the most active volcano of Kamchatka's eastern volcanic zone, is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene. The caldera cuts the south side of the Pleistocene Dvor volcano and is located outside the north margin of the large mid-Pleistocene Polovinka caldera, which contains the smaller Akademia Nauk and Odnoboky calderas. Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, which is located immediately south of Karymsky volcano. The caldera enclosing Karymsky volcano formed about 7600-7700 radiocarbon years ago; construction of the Karymsky stratovolcano began about 2000 years later. The latest eruptive period began about 500 years ago, following a 2300-year quiescence. Much of the cone is mantled by lava flows less than 200 years old. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.

BEZYMIANNY

As of the 17th of August, the Kamchatkan Volcanic Eruption Response Team (KVERT) has reported that growth of the lava dome continues. The activity of the volcano could affect low-flying aircraft in the vicinity of the volcano. Seismic activity was slightly above background levels on August 09-10 and 12-13 and did not exceed level of registration on the other days. Several shallow volcanic earthquakes were registered during the week. According to satellite data a thermal anomaly was noted on August 11, clouds obscured the volcano on the other days.

Prior to its noted 1955-56 eruption, Bezymianny volcano had been considered extinct. The modern Bezymianny volcano, much smaller in size than its massive neighbours Kamen and Kliuchevskoi, was formed about 4700 years ago over a late-Pleistocene lava-dome complex and an ancestral volcano that was built between about 11,000-7000 years ago. Three periods of intensified activity have occurred during the past 3000 years. The latest period, which was preceded by a 1000-year quiescence, began with the dramatic 1955-56 eruption. This eruption, similar to that of Mount St. Helens in 1980, produced a large horseshoe-shaped crater that was formed by collapse of the summit and an associated lateral blast. Subsequent episodic but ongoing lava-dome growth, accompanied by intermittent explosive activity and pyroclastic flows, has largely filled the 1956 crater.

SHEVELUCH

As of the 17th of August, the Kamchatkan Volcanic Eruption Response Team (KVERT) has reported that growth of the lava dome continues. Ash explosions up to 10 km (32,800 ft.) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft. Seismic activity was above background levels. Many shallow volcanic earthquakes and intermittent volcanic tremor were registered. According to seismic data, ash plumes up to 10 km (32800 ft) ASL and avalanches occurred at the volcano last week. According to visual data from Kluchi, intensive growth of the eastern part of the lava dome, incandescence of the dome and hot avalanches were noted on August 11-12. Two avalanches, accompanied with ash plumes up to 4.5 km (14800 ft) ASL extending to the north-west, were observed on August 14, clouds obscured the volcano in other days. According to satellite data, a big thermal anomaly was noted all week, diffused ash plume extended about 90 km (56 mi) to the south-east on August 11.

The high, isolated massif of Sheveluch volcano (also spelled Shiveluch) rises above the lowlands NNE of the Kliuchevskaya volcano group. The 1300 cu km Shiveluch is one of Kamchatka's largest and most active volcanic structures. The summit of roughly 65,000-year-old Stary Shiveluch is truncated by a broad 9-km-wide late-Pleistocene caldera breached to the south. Many lava domes dot its outer flanks. The Molodoy Shiveluch lava dome complex was constructed during the Holocene within the large horseshoe-shaped caldera; Holocene lava dome extrusion also took place on the flanks of Stary Shiveluch. At least 60 large eruptions of Shiveluch have occurred during the Holocene, making it the most vigorous andesitic volcano of the Kuril-Kamchatka arc. Widespread tephra layers from these eruptions have provided valuable time markers for dating volcanic events in Kamchatka. Frequent collapses of dome complexes, most recently in 1964, have produced debris avalanches whose deposits cover much of the floor of the breached caldera.

KLIUCHEVSKOI

As of the 17th of August, the Kamchatka Volcano Eruption Response Team (KVERT) reported that activity of Klyuchevskoy has decreased and KVERT is now assigning level of concern color code GREEN to the volcano: seismic activity was at background levels during the past five weeks, and ash plumes were not noted for the last four weeks. Seismic activity was at background levels last week, weak continuous spasmodic volcanic tremor and a few weak shallow earthquakes were registered. According to video and visual data, no activity was observed on August 11 and the volcano was obscured by clouds on the other days. According to satellite data, thermal anomaly was noted on August 11.

Kliuchevskoi is Kamchatka's highest and most active volcano. Since its origin about 6000 years ago, the beautifully symmetrical, 4835-m-high basaltic stratovolcano has produced frequent moderate-volume explosive and effusive eruptions without major periods of inactivity. Kliuchevskoi rises above a saddle NE of sharp-peaked Kamen volcano and lies SE of the broad Ushkovsky massif. More than 100 flank eruptions have occurred at Kliuchevskoi during the past roughly 3000 years, with most lateral craters and cones occurring along radial fissures between the unconfined NE-to-SE flanks of the conical volcano between 500 m and 3600 m elevation. The morphology of its 700-m-wide summit crater has been frequently modified by historical eruptions, which have been recorded since the late-17th century. Historical eruptions have originated primarily from the summit crater, but have also included numerous major explosive and effusive eruptions from flank craters.

The Current Colour Code for Kliuchevskoi is now at GREEN
~~~~~~~

SAKURA-JIMA

As of the 9th of August, the Japan Meteorological Agency (JMA), has reported that based on information from JMA, the Tokyo VAAC reported an explosion from Sakura-jima on 4 August. Ash was not detected on satellite imagery.

Sakura-Jima, one of Japan's most active volcanoes, is a post-caldera cone of the Aira caldera at the northern half of Kagoshima Bay. Eruption of the voluminous Ito pyroclastic flows was associated with the formation of the 17 x 23-km-wide Aira caldera about 22,000 years ago. The construction of Sakura-jima began about 13,000 years ago and built an island that was finally joined to the Osumi Peninsula during the major explosive and effusive eruption of 1914. Activity at the Kita-dake summit cone ended about 4,850 years ago, after which eruptions took place at Minami-dake. Frequent historical eruptions, recorded since the 8th century, have deposited ash on Kagoshima, one of Kyushu's largest cities, located across Kagoshima Bay only 8 km from the summit. The largest historical eruption took place during 1471-76.

SOUFRIERE HILLS

As of the 17th of August, the Montserrat Volcano Observatory (MVO) has reported that measurable activity has remained low with no significant changes over the last 24 hours, although low level rockfall activity continues. Lava extrusion has ceased and the dome is now in a passive state. Nevetheless, it remains as a large mass of partially molten lava capable of collapsing or exploding, although the likelihood of this decreases with time as no further lava extrusion occurs. The amount of material above Tyres Ghaut to the NW is sufficient to generate pyroclastic flows and surges capable of impacting on the lower Belham Valley and lower lying areas up to lower Happy Hill and the Old Towne ridge. The alert level remained at 4.

The complex, dominantly andesitic Soufrière Hills volcano occupies the southern half of the island of Montserrat. The summit area consists primarily of a series of lava domes emplaced along an ESE-trending zone. English's Crater, a 1-km-wide crater breached widely to the east, was formed during an eruption about 4000 years ago in which the summit collapsed, producing a large submarine debris avalanche. Block-and-ash flow and surge deposits associated with dome growth predominate in flank deposits at Soufrière Hills. Non-eruptive seismic swarms occurred at 30-year intervals in the 20th century, but with the exception of a 17th-century eruption that produced the Castle Peak lava dome, no historical eruptions were recorded on Montserrat until 1995. Long-term small-to-moderate ash eruptions beginning in that year were later accompanied by lava-dome growth and pyroclastic flows that forced evacuation of the southern half of the island and ultimately destroyed the capital city of Plymouth, causing major social and economic disruption.

The Current Colour Code for Soufriere Hills is currently at LEVEL 4

Mt. St. HELENS

"Live-Cam" of Mt. St. Helens.

As of the 17th of August, the Cascades Volcano Observatory (CVO) reported that growth of the new lava dome inside the crater of Mt. St. Helens continues, accompanied by low rates of seismicity, low emissions of steam and volcanic gases, and minor production of ash. During such eruptions, changes in the level of activity can occur over days to months. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.

Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that any ash clouds rising above the crater rim today would drift to the northeast.

The day dawns with yet another cloudless, scintillating day at Mt. St. Helens. Seismicity continues to be low with no unusual activity. USGS field crews had a productive day in the field yesterday. Projects included working on telemetry for one tiltmeter and removing a second that had filled with water, mapping geology on the north flank, surveying river channels, and performing various maintenance and upgrade tasks on several remote camera sites. The U.S. Geological Survey and the University of Washington continue to monitor the situation closely and will issue additional updates and changes in alert level as warranted.

Prior to 1980, Mt. St. Helens formed a conical, youthful volcano sometimes known as the Fuji-san of America. During the 1980 eruption the upper 400 m of the summit was removed by slope failure, leaving a 2 x 3.5 km horseshoe-shaped crater now partially filled by a lava dome. Mt. St. Helens was formed during nine eruptive periods beginning about 40-50,000 years ago, and has been the most active volcano in the Cascade Range during the Holocene. The modern edifice was constructed during the last 2,200 years, when the volcano produced basaltic as well as andesitic and dacitic products from summit and flank vents. Historical eruptions in the 19th century originated from the Goat Rocks area on the N flank, and were witnessed by early settlers.

POPOCATEPETL

As of the 17th of August, the El Centro Nacional de Prevención de Desastres de la Secretaría de Gobernación (CENAPRED) has reported that there were 8 exhalations accompanied by steam and gas emissions, and occasionally small amounts of ash. The other monitoring parameters remain without important changes. At the moment of this report CENAPRED can observe the volcano with steam and gas emissions.

Volcano Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano. At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.

PACAYA

As of the 15th of August, the Instituto Nacional de Sismologia, Vulcanologia, Meterologia, e Hidrologia (INSIVUMEH), after being translated from Spanish, reported that little it has been changed in observation due to the atmospheric conditions, and small explosions of 15 and 25 metres of height; continuous flow of lava in front of the Cerro Chino with lengths of 150 to 200 metres. Crater degassing continues with a plumein the north direction.

Eruptions from Pacaya, one of Guatemala's most active volcanoes, are frequently visible from Guatemala City, the nation's capital. Pacaya is a complex basaltic volcano constructed just outside the southern topographic rim of the 14 x 16 km Pleistocene Amatitlán caldera. A cluster of dacitic lava domes occupies the southern caldera floor. The post-caldera Pacaya massif includes the Cerro Grande lava dome and a younger volcano to the SW. Collapse of Pacaya volcano about 1100 years ago produced a debris-avalanche deposit that extends 25 km onto the Pacific coastal plain and left an arcuate somma rim inside which the modern Pacaya volcano (MacKenney cone) grew. A subsidiary crater, Cerro Chino, was constructed on the NW somma rim and was last active in the 19th century. During the past several decades, activity at Pacaya has consisted of frequent strombolian eruptions with intermittent lava flow extrusion that has partially filled in the caldera moat and armored the flanks of MacKenney cone, punctuated by occasional larger explosive eruptions that partially destroy the summit of the cone.

FUEGO

As of the 15th of August, the Instituto Nacional de Sismologia, Vulcanologia, Meterologia, e Hidrologia (INSIVUMEH), after being translated from Spanish, reported that with weak and moderate explosions, expelling gray ash to 300 and 500 metres from the crater with direction the west. Some of these explosions generated rumblings and some with weak shock waves.

Fuego, one of Central America's most active volcanoes, is one of three large stratovolcanoes overlooking Guatemala's former capital, Antigua. Collapse of the ancestral Meseta volcano about 8,500 years ago produced a massive debris avalanche that traveled about 50 km onto the Pacific coastal plain. Growth of the modern Fuego volcano followed, continuing the southward migration of volcanism that began at Acatenango, the northern twin volcano of Fuego. Frequent vigorous historical eruptions have been recorded since 1524 and have produced major ashfalls, along with occasional pyroclastic flows and lava flows. The last major explosive eruption from Fuego took place in 1974, producing spectacular pyroclastic flows visible from Antigua.

SANTA MARIA

As of the 15th of August, the Instituto Nacional de Sismologia, Vulcanologia, Meterologia, e Hidrologia (INSIVUMEH), after being translated from Spanish, reported that in the last 24 hours the volcano carried out 20 weak and moderate explosions, expulsion of gray ash 300 and 500 metres of height dispersing the column towards the southwest. Avalanches in the lava flow of the southwest were observed.

TUNGURAHUA

As of the 17th of August, the Instituto Geofisico (IG), after being translated from Spanish, reported that the seismic activity of the volcano presents/displays a moderate-high level with ascending tendency. In these last hours 3 volcanic explosions have been registered.

The registery has registered a total of 16 events of long period (LP) and 29 signals of tremor related to gas discharges and ash. Additionally 3 volcanic explosions of small size were registered, greatest of which happened yesterday at 1904hrs (local time) and had a reduced displacement of 2.2cm2. The volcano remains cloudy from the afternoon of yesterday with slight rains in the morning of today. The occurrence of lahars (mud flows) has not been reported. At night yesterdsay it was reported that slight roars generated by the volcano were heard in the population of Manzano (southwestern flank of the volcano) and Juive (northwestern flank).

The official colour of the volcanic alarm light remains on ORANGE

ERTA ALE

As of the 17th of August, the Ethiopian News Agency reported a possible new flank eruption from Erta Ale volcano in the Danakil desert. From the Ethiopian News Agency, according to the agency, two people are reported missing and several hundreds of villagers were forced to flee from their area by a lava flow.

Erta Ale is an isolated basaltic shield volcano that is the most active volcano in Ethiopia. The broad, 50-km-wide volcano rises more than 600 m from below sea level in the barren Danakil depression. Erta Ale is the namesake and most prominent feature of the Erta Ale Range. The 613-m-high volcano contains a 0.7 x 1.6 km, elliptical summit crater housing steep-sided pit craters. Another larger 1.8 x 3.1 km wide depression elongated parallel to the trend of the Erta Ale range is located to the SE of the summit and is bounded by curvilinear fault scarps on the SE side. Fresh-looking basaltic lava flows from these fissures have poured into the caldera and locally overflowed its rim. The summit caldera is renowned for one, or sometimes two long-term lava lakes that have been active since at least 1967, or possibly since 1906. Recent fissure eruptions have occurred on the northern flank of Erta Ale.

The Current Colour Code for Erta Ale is currently at ORANGE

RABAUL

As of the 16th of August, the Global Volcanism Network (GVN) reported that RVO reported that during 7-13 August, ash plumes from Rabaul caldera's Tavurvur cone rose to an altitude of 1.7 km (5,600 ft) a.s.l. and drifted N and NW. On 8 August, ashfall greater than 5 mm thickness was reported in Rabaul Town. During 10-13 August, ashfall was reported from areas downwind, including Rabaul Town. Rumbling and jet-like noises were heard and incandescence was seen at the crater during the reporting period.

The low-lying Rabaul caldera on the tip of the Gazelle Peninsula at the NE end of New Britain forms a broad sheltered harbour utilised by what was the island's largest city prior to a major eruption in 1994. The outer flanks of the 688-m-high asymmetrical pyroclastic shield volcano are formed by thick pyroclastic-flow deposits. The 8 x 14 km caldera is widely breached on the east, where its floor is flooded by Blanche Bay and was formed about 1400 years ago. An earlier caldera-forming eruption about 7100 years ago is now considered to have originated from Tavui caldera, offshore to the north. Three small stratovolcanoes lie outside the northern and NE caldera rims of Rabaul. Post-caldera eruptions built basaltic-to-dacitic pyroclastic cones on the caldera floor near the NE and western caldera walls. Several of these, including Vulcan cone, which was formed during a large eruption in 1878, have produced major explosive activity during historical time. A powerful explosive eruption in 1994 occurred simultaneously from Vulcan and Tavurvur volcanoes and forced the temporary abandonment of Rabaul city.

The volcano Rabaul is currently at the ALERT LEVEL 1

KILAUEA

"Live-Cam" of Pu`u `O`o.

As of the 16th of August, it has been reported to INTLVRC direct from the Hawaiian Volcano Observatory (HVO), that the effects of Tropical Storm Flossie are decreasing. The 7/21 fissure eruption continues to feed a channel and lava flow. A magnitude-4.2 earthquake occurred at 0223hrs and was located 2.5 miles south of Mauna Ulu beneath the south flank at a depth of 9 km (5 miles).

Last 24 hours at 7/21 eruption site: Weather has made webcam viewing difficult but the active was seen last night. The webcam has been blocked by wet weather since the M4.2 earthquake. Vent areas are hazardous and conditions can change rapidly. Access to the 7/21 eruption site in the Kahauale`a Natural Area Reserve is closed.

Last 24 hours at Pu`u `O`o crater: The webcam is still down. The tiltmeter on the north flank of Pu`u `O`o cone flattened out and maybe recording inflation, possibly due to rainfall. Seismic tremor levels at Pu`u `O`o and nearby areas decreased as Tropical Storm Flossie passes to the south.

Last 24 hours at Kilauea summit: The tiltmeter network continued to record slow deflation. Seismic tremor levels were low. A few small shallow earthquakes were again located beneath Halema`uma`u crater.

ARENAL

As of the 16th of August, the Observatorio Vulcanológico y Sismológico de Costa Rica via the Global Vlocanism Network (GVN) reported that in July, activity originating from Arenal's Crater C consisted of gas emissions, sporadic Strombolian eruptions, lava flows traveling SW and S, and occasional avalanches from lava-flow fronts. Blocks from the lava-flow fronts periodically reached vegetation and started small fires. Volcanic activity was at relatively low levels and few eruptions occurred. Small amounts of pyroclastic material were ejected and affected the NE and SE flanks. Eruptions produced ash plumes that rose about 2.2 km (7,100 ft) a.s.l. Ash and acid rain fell on the NE and SE flanks. Small avalanches of volcanic material traveled down several ravines. Crater D showed only fumarolic activity.

The Arenal Volcano, in Spanish Volcán Arenal, is an active andesitic stratovolcano in north-western Costa Rica (10.5N, 84.7W), around 90 km north-west of San José, in the province of Alajuela. Recognised as a volcano since the 19th century, it was known by foreign investigators as "Volcan Costa Rica, Rio Frio", "Canastos" Volcano and "Cerro de los Guatusos". Arenal is the youngest and most active of all the mountains in Costa Rica. Scientists have been able to date it back to more than 4000 years ago. The area remained largely unexplored until 1937, when a documented expedition took place to reach the summit.

STROMBOLI

As of the 10th of August, the Instituto Nazionale di Geofisica e Vulcanologia - Sezione di Catania has reported that as colleague Andrea Ercolani reports from Stromboli, access to the summit area of Stromboli has been reopened for guided tours under certain restrictions. In brief, small groups accompanied with authorised guides can now reach the ridge east of the crater terrace between 750 and around 850 m elevation where a few shelters are located, but the maximum stay is now limited to 30 minutes. Access to the Pizzo summit itself is limited to the time necessary for passing along the trail.

Spectacular incandescent nighttime explosions at Stromboli volcano have long attracted visitors to the "Lighthouse of the Mediterranean." Stromboli, the NE-most of the Aeolian Islands, has lent its name to the frequent mild explosive activity that has characterised its eruptions throughout much of historical time. The small, 924-m-high island of Stromboli is the emergent summit of a volcano that grew in two main eruptive cycles, the last of which formed the western portion of the island. The Neostromboli eruptive period from about 13,000 to 5000 years ago was followed by formation of the modern Stromboli edifice. The active summit vents are located at the head of the Sciara del Fuoco, a prominent horseshoe-shaped scarp formed about 5000 years ago as a result of the most recent of a series of slope failures that extend to below sea level. The modern volcano has been constructed within this scarp, which funnels pyroclastic ejecta and lava flows to the NW. Essentially continuous mild strombolian explosions, sometimes accompanied by lava flows, have been recorded at Stromboli for more than a millennium.

WOW!

I have quite a few meteor helmets left that didn't sell. I wonder if I could sell the remaining inventory by calling them "volcano helmets"?

I wanted to repeat something that many of our readers and guests might not know. Natural disasters are one of the signs in Bible Prophecy of the end days of this Age of Grace. However, natural disasters are just one piece of the puzzle. There are other pieces of this Big Bible Prophecy Puzzle that are beginning to fall into place, and the pieces fit. The question becomes - how long might it take for the rest of the pieces to fall into place?

People who study Bible Prophecy are beginning to think that it might not take much to finish the picture in the "puzzle". Most know better than to try setting dates and times, but "soon" is a word that is often used these days.

There are all kinds of people in this dying world, and it's interesting to consider some of the possible reactions to information like this. As examples:

"There goes the religious nuts again." - from the lost and worldly.

"What are they talking about?" - from those without a clue?

"What's Bible Prophecy?" - from those who are interested but don't understand.


One could easily use the imagination and come up with tons of additional examples. The truth of the matter is that very few people understand what we're talking about. Sadly, that includes many Christians who haven't studied their Bibles often enough. So maybe this is a good opportunity to make some very general statements about things that will happen soon:

JESUS  CHRIST will catch up Christians, living and dead, to meet HIM in the air - forever to remain with HIM. This is called the Rapture.

The world will suffer a horrible 7 year period of time called the Tribulation Period. This will be a time of horror, terror, and blood-shed like the world has never known. Israel will be the central focus of this time period.

JESUS CHRIST HIMSELF will come again at the end of the Tribulation Period, and it will be in GREAT, HOLY WRATH. Most of the peoples of the world will die, and JESUS CHRIST will defeat evil.

JESUS CHRIST will restore Israel and claim HIS Throne as Israel's Anointed KING. JESUS CHRIST will rule and reign over the earth from the Throne of David in Jerusalem for 1,000 years. This period of time is known as the Millennial Kingdom. Please note this is separate and distinct from GOD'S Heavenly Kingdom that is already in place.


So, what is so important about all of this? Mankind has been forewarned of it for thousands of years from the pages of the Holy Bible. Bible Prophecy is Promises made by GOD through HIS WORD, the Holy Bible, that will happen in the future. The First Coming of JESUS CHRIST and the CROSS was one such example, and that Bible Prophecy was fulfilled about 2,000 years ago. The time is growing short for people to accept JESUS CHRIST as Lord and Saviour. The time is also growing short for Christians to witness to their family, friends, and neighbors. Those who reject CHRIST will pay a horrible and eternal price.

We aren't talking about the end of the world, rather the start of a new age in GOD'S Plan for mankind. It will be a time for GOD to fulfill many Promises. It will involve a wonderful time for Christians and a horrible time for the lost. Christians will go on to their rewards in Heaven, and the lost will await their judgment for eternal punishment. In the age we are living now, ALMIGHTY GOD is still displaying HIS patience and love for disobedient and sinful man. GOD told us in the Holy Bible that this period of time would end, and HE will pour out HIS RIGHTEOUS WRATH on evil men. This is the TIME that is coming soon! Sadly, great hosts will reject JESUS CHRIST and hurry on their present course to the ETERNAL FIRES OF HELL!

If you haven't accepted JESUS CHRIST as your LORD and SAVIOUR, please read the following post. If you have questions or need help in making your decision, please ask. Many Christians will be most happy to help you.


Love In Christ,
Tom

GOOD NEWS!

1:  Romans 3:10 NASB  as it is written, "THERE IS NONE RIGHTEOUS, NOT EVEN ONE; THERE IS NONE WHO UNDERSTANDS, THERE IS NONE WHO SEEKS FOR GOD; ALL HAVE TURNED ASIDE, TOGETHER THEY HAVE BECOME USELESS; THERE IS NONE WHO DOES GOOD, THERE IS NOT EVEN ONE."

2:  Romans 3:23  NASB  for all have sinned and fall short of the glory of God,

3:  Romans 5:12  NASB  Therefore, just as through one man sin entered into the world, and death through sin, and so death spread to all men, because all sinned--

4:  Romans 6:23  NASB  For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.

5:  Romans 1:18  NASB  For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness,

6:  Romans 3:20  NASB  because by the works of the Law no flesh will be justified in His sight; for through the Law comes the knowledge of sin.

7:  Romans 3:27  NASB  Where then is boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith.

8:  Romans 5:8-9  NASB  But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him.

9:  Romans 2:4  NASB  Or do you think lightly of the riches of His kindness and tolerance and patience, not knowing that the kindness of God leads you to repentance?

10:  Romans 3:22  NASB  even the righteousness of God through faith in Jesus Christ for all those who believe; for there is no distinction;

11:  Romans 3:28  NASB  For we maintain that a man is justified by faith apart from works of the Law.

12:  Romans 10:9  NASB  that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved;

13:  Romans 4:21  NASB  and being fully assured that what God had promised, He was able also to perform.

14:  Romans 4:24 NASB  but for our sake also, to whom it will be credited, as those who believe in Him who raised Jesus our Lord from the dead,

15:  Romans 5:1  NASB  Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ,

16:  Romans 10:10  NASB  for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.

17:  Romans 10:13  NASB  for "WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED."


Thanks be unto GOD for HIS unspeakable GIFT!, JESUS CHRIST, our Lord and Saviour forever!

Volcano in Eastern Indonesia Spews Lava, Hot Ash

Monday , August 20, 2007

AP

JAKARTA, Indonesia —
A volcano in eastern Indonesia spewed hot lava and clouds of ash high into the air early Monday, a vulcanologist said, hours after hundreds of villagers living on its rumbling slopes were evacuated.

There were no reports of injuries or damage, said Yudi Satipang, a vulcanologist who has been monitoring Mount Karangetang on Siau island since it was placed on high alert over the weekend.

"It sounds like huge thunderclaps," he said of the booming gas blasts from the crater, adding that villages, farms and trees on the 5,577-foot -tall mountain were covered in thick gray ash.

Karangetang is one of Indonesia's most active mountains, and it has been rumbling for days.

Nearly 600 residents living within the danger zone have fled to safety, and many were seeking shelter in government buildings, schools and mosques.

Indonesia, the world's largest archipelago, is prone to seismic upheaval due to its location on the so-called Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.

Siau, a popular diving island, is part of the Sulawesi island chain. It lies some 1,444 miles northeast of the country's capital, Jakarta.
