Luke
21:[25] And there shall be signs in the
sun, and in the moon, and in the stars; and upon the earth distress of nations,
with perplexity; the sea and the waves roaring; [26] Men's hearts
failing them for fear, and for looking after those things which are coming on
the earth: for the powers of heaven shall be shaken. [27] And then shall
they see the Son of man coming in a cloud with power and great glory. [28]
And when these things begin to come to pass, then look up, and lift up your
heads; for your redemption draweth nigh.

October - Volcanoes 2010: October 5... There have been reports of increased sulfur odor and sulfur dioxide emissions, increased seismicity in the edifice (tens of earthquakes) over the weekend (2nd -3rd) at Nevado del Ruiz Volcano, in Colombia, South America.
September - Volcanoes 2010: September
1… There has been a volcanic eruption in Virunga National Park in the
Democratic Republic of Congo. The volcano has not been named, but both
Nyiragongo Volcanoes and Nyamuragira Volcanoes are located within the park. The volcanic
eruption is in the eastern region of Congo, sending lava toward a national park,
threatening wildlife, in the sparsely populated region. Scientists recorded
significant increased volcanic activity around Goma in the east of the country.
September 2, 2010... Mt. Seulawah Agam Volcano in Indonesia is on the
lowest alert level following a series of earthquakes recorded in the last few
days. There is an increase in the frequency of the mount’s volcanic activities,
particularly earthquakes. During the month of August there were recorded 80
volcanic quakes or almost three times per day and 40 tectonic quakes.
September 6, 2010... Mount Sinabung shot black ash and debris three
miles into the air, with bursts of fire and hot ash. The force of the explosion
could be felt 5 miles away.
01. For more information on Sinabung Volcano, scroll down this page to August 29-30...
September 7, 2010... There was a small explosion at Mount Peteroa in
Chile.
September 29, 2010... There have been several News Reports about the lava field of Harrat Lunayyir, which is a "lave province" that began forming when Arabia split from Africa, rifting that helped create the Red Sea. There has been a 2-mile long and 5-mile rupture, during the most powerful earthquake. There were about 30,000 earthquakes between April and June 2009; with 19 earthquakes of magnitude 4.0 or greater. The largest was 5.4. Magma has risen to about a mile below the surface.
August - Volcanoes 2010: August 6, 2010... Mount Karangetang, one of Indonesia’s most active volcanoes, erupted on
Friday, leaving four people missing, according to Priyadi Kardono, a
National Disaster Mitigation Agency official.
August 25, 2010... Galeras Volcano has erupted with smoke, ash and water vapor. It is considered the most active volcano in Colombia. A 4.6 magnitude earthquake has occurred near the summit and nearly 400 minor tremors.
August 29...& 30, 2010... Mount Sinabung, Indonesia is currently in a state of eruption, after 410 years of inactivity. It is spewing lava, superheated sand, black and white smoke and a thick ash cloud, with a sulfur smell. There have been reports of an earthquake in the vicinity of the volcano, before the eruption.
July - Volcanoes 2010: July 8... Mount Longonot National
Park volcano may go active.
Satellite pictures
taken over the past decade apparently indicate that the mountain has
grown in
elevation by several inches, a tell-tale sign of increased volcanic
activity
well below the surface, caused by rising magma.
July 25, 2010... Authorities declared a
yellow alert for the Machin volcano located in Colombia's central Tolima
department, following an increase in registered seismic activity in the area.
Registered 68 tremors over the weekend, one measuring 2.6 on the Richter scale
which was felt by locals in the zone.
July
27, 2010… Costa
Rica - The Volcán Irazú shook and shook and shook - a total of 31 times -
between 5am and 11am on Thursday, the 26th, though only one of the tremors was perceived
by the population, registering 3.1 on the Richter scale.

June - Volcanoes 2010:June 2... Cleveland volcano in
the Aleutian Islands in southwest Alaska is showing signs of unrest. The Alaska
Volcano Observatory says there was a small ash emission from Cleveland Volcano
on Sunday evening and satellite images received Monday, May 31, indicated flows coming
from the volcano's upper flanks. The volcano 939 miles from Anchorage is on an
uninhabited island. Short-lived explosions with ash clouds or plumes exceeding
20,000 feet above sea level are frequent on Cleveland, which last showed signs
of unrest in the fall of 2009.
June
7, 2010…
Eurasia's highest volcano on the Kamchatka Peninsula in Russia's Far East has
shown again signs of intensified activity throwing clouds of smoke and ash into
the air to a height of 2.5 kilometers. The Klyuchevskoy,
which lies 220 miles north of Petropavlovsk-Kamchatsky, is one of the largest
active volcanoes in the world. It erupts about every 2-3 years.
June
8, 2010…
Two volcanoes in Vanuatu, Gaua and Ambrym, emitted simultaneous plumes on
Sunday, June 6. Gaua emited a thick, tan plume that blew toward the southwest.
The plume’s color indicates the presence of volcanic ash. Ambrym emited a faint
plume that blew toward the south and appears blue-gray, probably because the
blue of the ocean shows through the nearly transparent plume. This plume’s pale
color suggests water vapor. Two red hotspots on Ambrym are associated with high
surface temperatures, and almost certainly result from volcanic activity.
June 9, 2010…
The Philippine Institute of Volcanology and Seismology on Tuesday raised the
alert level status of Taal Volcano
from alert level 1 to alert level 2 as it is showing signs of possible
eruption. On its website, Phivolcs said it has noticed “anomalous change” since
the last week of April. Among its observations were increased and intensifying
volcanic earthquakes, including a low frequency type volcanic earthquake
detected on June 2; raised temperature in the main crater lake; raised ground
temperatures; intensified steaming of the main crater; and inflating of the
volcano. “The recorded high frequency volcanic earthquakes could be the result
of active rock fracturing associated with magma intrusion beneath the volcano.
The fractures served as passageways through which hot gases from the intruding
magma could escape into the main crater lake."
June
12, 2010… Gorely Volcano - In the Russian Far East,
Kamchatka’s Gorely volcano is spewing steam and ash again AFTER DECADES IN
DORMANCY. The plume has stretched to over a hundred kilometers, compromising
regional air travel and threatening disruption at a local geothermal power
plant. Mount
Gorely rises to about two kilometres above sea level. There are 11 craters on
it, one with a lake. The volcano’s average dormancy interval is close to 20
years.
June
14, 2010… Sarychev Volcano - Almost a year after it
spectacularly erupted, Sarychev Volcano showed more modest signs of activity on
June 11. Satellite images show apparent water vapor filling Sarychev’s summit
crater, forming an almost perfect circle of white. A much fainter, barely
discernible plume blows away from the summit toward the east. Sarychev Peak is
a stratovolcano and reaches a height of 4,908 feet. It forms the
highest point on Matua Island. This volcano ranks among the most active in the
Kuril Islands, which extend southwestward from the Kamchatka Peninsula.
June 15, 2010... Mount Ulawun Volcano - Disaster officials are on
alert as one of the country's highest active volcanoes shows signs of an
eruption. PNG's Mount Ulawun volcano in West New Britain province has been
emitting vapor over the last few weeks.
June 21, 2010... An
explosive eruption at Mt. Sakurajima in Kagoshima Prefecture on Sunday
afternoon was the 549th this year, a new annual record. A second explosive
eruption occurred later in the day, the 550th this year.
June 24-28, 2010… The Shiveluch volcano on the
Russian Kamchatka Peninsula has erupted, producing an ash plume of 6.5
kilometers. The northernmost active volcano on Kamchatka Peninsula is spewing
plumes of ash at a height of more than 6 kilometers. Mt. Shiveluch has been
erupting for many days now with 80 underground temblors registered in the past
24 hours alone.
May - Volcanoes 2010:May 25, 2010... Mountain Baekdu, a dormant volcano on
the border between North Korea and China, is showing signs of a possible
eruption in the near future. "Baekdu could erupt anytime soon. A variety
of indicators are backing this scenario. It's clear it's imminent." Major
activity in the 1960s created a caldera on its peak. Volcanic ash from this
eruption has been found as far away as the southern part of Hokkaido, Japan.
Small-scale eruptions were recorded roughly on a centurial basis - in 1413,
1597, 1668 and 1702. The latest volcanic eruption recorded at the mountain was
back in 1903. The mountain has stayed inactive since then, leaving it
categorized by scientists as dormant. Yet, "UNUSUAL SIGNS," including
minor trembling among others, began to emerge in June 2002 and a 7.3-magnitude
earthquake rattled areas in the vicinity of Baekdu. The frequency of the quakes
has notably increased since then. "It
seems that a shockwave from the quake reactivated magma approximately 30
kilometers beneath the mountain. The more frequent these are, the higher the
possibility of an eruption." Minor quakes which are too weak to be felt by
human beings take place nearly 100 times per day. "We saw the number
steeply increase in recent years." Among other indicators backing the
scenario of a future eruption is the height of Baekdu, which has grown nearly
10 centimeters since 2002. Experts say bloated magma, a precondition of
eruption, is gradually pushing up the height of the mountain as well as the
temperature on the surface. On October 1, 2006, a Russian satellite found the
surface temperature of the mountain notably higher than before. The finding
came just days after North Korea conducted an underground nuclear bomb test in
its northern region, indicating the test was a catalyst reactivating the magma,
analysts said. The increase in the number of withered evergreen trees on the
mountain may be another indicator. If
the eruption is major in scale, it would bring about massive consequences to
the two Koreas as well as the surrounding states, including China, Japan and
Russia. "The amount of volcanic ash from the most violent eruption nearly
1,000 years ago was enough to cover the entire the Korean peninsula to a height
of 1.2 meters. Baekdu's caldera contains nearly two billion tons of water. If
it evaporates into the air all of a sudden mixed with volcanic ash of a major
eruption, it would be blown to the east and consequently engulf Vladivostok in
Russia and Hokkaido in northern Japan.
May 27, 2010... Guatemala's Pacaya volcano started erupting
lava and rocks, blanketing the country's capital with ash and forcing the
closure of the international airport.
May 29, 2010... Strong explosions rocked Ecuador's Tungurahua
volcano, prompting evacuations of hundreds of people from nearby villages. Hot
volcanic material blasted down the slopes and ash plumes soared 6 miles above
its crater.
May 30, 2010... A giant plume of volcanic ash has erupted over
the South Pacific. The cloud billowing
from Vanuatu's Mount Yasur volcano rose about 6,000 feet. Last week there was a
very high activity for the volcano with hot lava, hot rocks falling from the
volcano.
May 31, 2010... A submarine
volcanic eruption is underway near the uninhabited Sarigan Island in the
Northern Mariana Islands 3,800 miles southwest of Hawaii, in the Pacific
Ocean.
April - Volcanoes 2010: The swarm of small, shallow earthquakes that began Monday, April 5, 2010, at Redoubt Volcano has greatly decreased over the past several days, and is
approaching background levels of activity. A gas measurement and
observation flight on Thursday, April 8 showed no disruption of the lava
dome and measured gas levels were consistent with a passively degassing
and cooling dome. It appears less likely that this current episode of
unrest will lead to resumed eruptive activity. Although the volcano
remains somewhat restless, we would expect a greater degree of seismic
activity, significantly elevated gas emissions, and melting of snow and
ice on the lava dome if conditions were escalating toward eruption.
The Institute of Earth Sciences reported that on 7 April, 2010, the eruption from Eyjafjöll ceased from the original eruption cratersand was limited to the fissure that had opened on 31 March. Lava flows coveredan estimated area of 1.3 square kilometers and were on average 10-20 m thick.The largest scoria cone was 82 m high. After minor changes in deformation ratesduring the eruption, on 9 April deformation returned to pre-eruption levels.Eruptive activity was observed on 11 April, but tremor decreased to baselinethe next day. Also on 12 April, according to a new article, the Icelandic CivilProtection Department decided to lower the preparedness level by one point,from emergency to danger because of the decreasing activity. Another articlestated that a pilot saw no active lava flows, only steam plumes, during anoverflight on 13 April.
At 2300 on 13 April, 2010, a seismic swarm was detectedbelow the central part of Eyjafjöll, W of the previous eruption fissures. Aboutan hour later, the onset of seismic tremor heralded an eruption from a new venton the S rim of the central caldera, capped by Eyjafjallajökull glacier. Theeruption was visually confirmed early in the morning on 14 April; an eruptionplume rose at least 8 km above the glacier. Meltwater flowed to the N and S.News outlets reported that a circular ice-free area about 200 m in diameter wasseen near the summit. Scientists conducting an overflight saw a new 2-km-long,N-S-trending fissure, and ashfall to the E. About 700 people were ordered toevacuate the area, and certain flights were banned from flying N and E of theeruption area. Flooding increased throughout the day, causing road closures andsome structural damage.
March - Volcanoes 2010:COSTA RICA - The Irazú volcano sent apanic chill in the neighbouring communities Monday night, as residents reportedat least 9 tremors from the volcano during a 30 minute period. Residents saythe volcano, located north of Cartago, began acting up after 7pm. None of thetremors felt were above 3 on the Richter scale. There was panic among theresidents who envisioned the fresh television and newspaper images of the deathand destruction of the 8.8 earthquake in Chile. The Irazú is located next to the Turrialba volcano that has beenactively spewing ash and gases for the last several months. Also fresh in theminds of Irazú residents is the death and destruction of Cinchona last January8, 2009, that is located near the Poás volcano, a short distance from Irazú.The Irazú has recorded 23 eruptions during its history, with its first recordederuption in 1723. The latest explosion by the colossus was in 1965 and 1963.
ICELAND - Theseismic activity in the area around Eyjafjallajökull glacier in south Iceland,which covers an active volcano, increased again Tuesday night with a series ofsmaller earthquakes measured between 3:40 and 5:20 am. The largest quake was2.6 on the Richter scale. The night-time tremors were stronger than thosemeasured Tuesday morning. The series of quakes was similar in character andlasted for approximately one hour. Magma flow seems to be at full speed insidethe volcano and the series of earthquakes probably indicates a magma intrusion.It is not known how volcanic eruptions begin in Eyjafjallajökull - it lasterupted in 1821 - and magma movements might continue for a few weeks.
INDONESIA -Seventeen of 18 volcanoes in Indonesia are on alert status and emitting toxicgas. The alert status is the second level of a three-level system of warning.The Ibu volcano in West Halmahera is the only one of the 18 volcanoes at thelower No. 3 standby level. Mount Talang in Sumatra and Mount Karangetang inSulawesi are the most recent volcanos to have their status raised to alert.Other Indonesian volcanoes on alert include Krakatoa, Bromo, Kaba, Anak, Slametand Lokon. In 1883, Krakatoa erupted in an explosion equivalent to 200 megatonsof TNT, about 13,000 times the force of the U.S. bomb that devastatedHiroshima, Japan, during World War II.
RUSSIA - Abelching of ash to the altitude of seven kilometers above sea level has beenregistered over the crater of the Shiveluch, Kamchatka’s northernmost activevolcano. The exuding of ash does not pose any risks for nearby populationcenters, as no data on the fallout of volcanic dust there has been reported.The belching was not seen visually and scientists drew a conclusion that it hadtaken place on the basis of information from seismic observation stationslocated in the vicinity of the volcano. They registered “a surface seismicevent at the volcano” having a four minutes’ duration. At this moment, thevolcano displays weak or moderate eruption periods lasting from several monthsto two to three years. The periods of its activation were registered in 1980 to1981 and 1993 to 1995. The last eruption ranking among disasters occurred inNovember 1964. The Shiveluch activated again in 2001, with a growth of theextrusive cupola – a towering of viscose lava -- evidenced in its crater.Geophysical services and agencies keep the giant under permanent watch.Klyuchevskaya volcano continues to be active- emitting steam, ash, and lava inearly 2010.
MONTSERRAT - Passengers on a jet flying over the Caribbean have received aclose-up look at a massive volcanic eruption sending ash and dust higher thanthe plane itself. The 737 jet was flying to the holiday destination of St Luciawhen it passed the Soufriere Hills volcano on the island of Monserrat midwaythrough its eruption. Passengers rushed to the windows to see the explosion andsubsequent mushroom cloud. The volcano sent a plume of ash as high as 12,000metres, prompting other flight delays after fears the dust would get into theengines. The partial collapse of the volcano's lava dome is believed to beresponsible for the ash cloud.
February - Volcanoes 2010:ECUADOR - Activityat Tungurahua volcanois increasing. It hasn't really made it to much ofthe English-speaking news,but the current eruptive activity atTungurahua appears to be on theup-tick.The Geophysical Institute ofEcuador suggests that a larger eruption isnot out of the question , butright now the activity is confined to explosionsand ash fall around theregion. The Geophysical Institute is reporting 32explosions, 30long-period seismic events and 20 episodes of volcanic tremor inthelast 24 hours.
PAKISTAN - A volcano has startedspewinglava in Ziarat District of Balochistan, some 75 kilometres awayfrom Quetta.The volcanic activity occurred in Jhari area of Ziarat atTorghar Mountain onMonday night. Residents of the nearby area claimedthe fire fumes at top of themountain in the night were witnessed forthe last few days, while on Mondaynight the mountain started spewinglava. Jhari area is located near Waam, whichwas badly affected inOctober 29, 2008, when a severe earthquake hit Ziarat.
MONTSERRAT -On Friday, therewas an explosion within the Soufriere Hills volcano, sendingplumes ofash more than 20,000 feet in the air. The event occurred at 1:49pm,lasting seven minutes and sending pyroclastic flows mainly to thewest of thevolcano “rapidly reaching Plymouth (the old capital) andspreading across thesea for around 500 miles”. Short pyroclastic flowsalso travelled down TyersGhaut to the northwest and Whites Ghaut to thenortheast of the island.
MONTSERRAT -The volcano onMontserrat shot ash some nine miles (15 kilometers) into theskyThursday, one of its most dramatic events since a devastating 1997eruptionthat drove away half the Caribbean island's population. Thepartial collapse ofthe dome in the volcano's crater also unleashedflows of hot gas and rocks,triggering sirens for the evacuation ofabout 20 people from a nearby village.It appeared to be the mostmaterial ejected by the volcano in about four years.10 percent to 15percent of the hardened lava dome collapsed. The dome hascrumbledseveral times since the volcano became active in 1995, and itispossible activity will settle down as the dome builds itself upagain. There isno immediate cause for concern about more dangerouseruptions.
HAWAII - Lava from Kílauea volcanoonce again has oozed through the mostlyabandoned Royal Gardenssubdivision, covering portions of the small open areasuntouched byprevious flows. The volcano has been erupting since 1983 and overtheyears has destroyed an estimated 66 homes or other structures inRoyalGardens. Lava from the "2007 Thanksgiving Eve Breakout" ventwasflowing through the upper 2 miles of the lava-tube system above thesubdivisionand feeding surface flows that were advancing slowly downthe pali and acrossthe coastal plain. A half-dozen channelized flowsmeandered down a steepportion of the pali last week, burning vegetationin the western part of RoyalGardens. Lava has not been flowing into theocean for at least a month.
INDONESIA -Nearly 50,000 internally displaced persons in Indonesia still lackbasicservices and are awaiting full compensation after a mudflowdestroyedhomes and farmland almost four years ago. Originating from amud volcano in thedistrict of Sidoarjo in East Java Province, themudflow and toxic gas emissionsstarted in May 2006 and still continue,with the volcano expelling 60,000 cubicmetres of watery mud daily. Some14,000 houses have been submerged. A newgeyser has been found about1.5km from the mud volcano in Sidoarjo, sparkingfears of further dangerto surrounding communities. "It's a small geyserbut it can be just asdangerous as large ones, because they all emit methanegas, which ishighly flammable, smelly and can cause headaches." There arealsoconcerns over the stability of huge earth dikes - some as high as 18m-which were built to contain the mud. "Because Sidoarjo experienceshighlevels of rainfall, the land is vulnerable to subsidence." "Thedikesonce dropped 3m. They could drop again, but we have peoplechecking for cracksevery day." Geologists are unsure when or how thevolcano will stopexpelling mud and gas. "The amount of mud that'scoming out now has halvedsince 2006, so maybe it will halve again inthree years. So it could be over in10 or so years, but of course, wecan't be sure of that."
CHILE - Steamseen from Llaima Volcano. Video surveillance confirms volcano is producingsteam, sometimes gas and could be set to erupt, experts say. Llaima Volcano,one of the largest and most active volcanoes in Chile, is located 663kilometers southeast of Santiago. The volcanic alert level has been raised toYellow Alert Level 3, with ongoing monitoring of the volcano for 24 hours aday. A report indicated there was fluid within the ducts of the volcano and intensevolcanic activity, which could indicate Llaima Volcano, is approaching a stateof imbalance. The last major eruption occurred in 1994, but an eruption inJanuary 2008 forced hundreds of villagers to evacuate the area with ash fallingas far as Argentina.
DEMOCRATIC REPUBLIC OF CONGO - Perched on a hillside, the volcano observatoryin Goma commands a great view of nearby Nyiragongo Mountain. "Goma facesthe highest risk any city in the world could face. We don't just havevolcanoes; we have gas emissions, acid rain, polluted water and endemicfluorosis. People are asphyxiated in this region every year, because there arefractures emitting carbon dioxide all over the rift." "It isdifficult to estimate the number of people who are dying. People who livearound here know where the gas is, so they avoid it. But there were more deathswhen IDPs [internally displaced people] came to this region because they did notknow where the gas is." Nyiragongo is one of the two active volcanoes inNorth Kivu. The other, Nyamulagira, erupted on 2 January, spewing lava 10kmaway and threatening the town of Sake and the Sake-Goma road. Sake is a majorsource of Goma's fresh food. That eruption was Nyamulagira's 35th since 1882.Little damage occurred because the lava mainly flowed into Virunga NationalPark. Two days later, the lava movement increased, flowing 500m within 24hours.
JAPAN -Sakurajima volcano erupted more than 400 times during 2009 and activity isincreasing. Ashfall is a regular occurrence at the daikon and mandarin farmssurrounding the volcano, as well as the nearby cities of Kagoshima andKirishima.
CHILE - Chaiten volcano has been placed under red alert due to an increase inseismic activity for three weeks. The volcano in southern Chile became activein May 2008 after being dormant for more than 9,000 years. Volcanic activitywas on the decline in the past few months until picking back up January 21. Thered alert, which indicates activity, is above normal levels and an eruptioncould be imminent, was enacted in large part to protect tourists in the area.Underground seismic rumblings 1.2 to 5 miles (2 to 8 kilometers) deep in thearea around the volcano and constant gas eruptions in the dome indicate "ahigh grade of instability".
January - Volcanoes 2010: YELLOW STONE NATIONAL PARK was rattled by 270 earthquakes in the last two days (as of3pmMonday) following a period of 11 months of quiet seismic activity inthe park.The quakes have been gaining strength, with a 3.1 tremorrecorded at 11:03 a.m.Monday. The quakes are occurring in an area about5 miles from where thelargest swarm of quakes ever was recorded inOctober 1985. One of the leadingexperts on earthquake and volcanicactivity at Yellowstone said that theactivity is a "notable swarm." Theswarm is located about 10 milesnorthwest of Old Faithful, Wyoming, andnine miles southeast of WestYellowstone, Montana. Such swarms are"relatively common." Today'stremors seem to be normal tectonicactivity, and are "not anindication" that some sort of volcanicactivity will occur. Since 1995there have been 80 swarms, including theone that started Sunday. In lateDecember 2008 and early January 2009,Yellowstone National park experienced thesecond largest earthquakeswarm in Yellowstone's recorded seismic history. Theswarm under thenorth end of Yellowstone Lake consisted of 813 earthquakeswithmagnitudes ranging up to 3.9. The eventual 'big one' will likelyoccur alongone of the 45 faults that line two belts - one stretchingfrom YellowstoneNational Park up to Helena, Montana, and a second onealong the Montana-Idahoborder. The Yellowstone Plateau is one of thelargest super-volcanoes in theworld and has gone through three volcaniccycles spanning two million years,which included some of the world'slargest known eruptions. There is absolutelyno connection between whatis occurring in Yellowstone and the magnitude 7.0earthquake in Haiti."They are completely different systems. They are notrelated." 1,033Yellowstone quakes recorded in one week. The Volcano AlertLevel atYellowstone National Park remained at “normal” Friday, despite aswarmof earthquakes large enough to trigger seismographs in theFlathead Valley andcause chatter on Twitter. Working around the clock,scientists with the U.S.Geological Survey’s Yellowstone VolcanoObservatory had recorded more than1,033 earthquakes since Monday,including at least eight events over magnitudethree. That’s more thanhalf the total annual average in the park, which is1,600 a year.Despite the flurry of activity, however, many Yellowstone localshaven’tfelt a thing, and scientists are calling the swarm of quakes typicalforthe seismically prone region that is home to one of the world’slargervolcanoes. “This is a big swarm. These things don’t happen veryoften. They mayhave a deep volcanic connection, but right now, it seemsto be related totectonics.” There was a similar swarm in 2009. Theswarm is on par with anevent in 1985 in which scientist recorded morethan 3,000 quakes. “It’sinteresting, with swarms, the earthquakes canstart up small. There’s no onebig earthquake, there are just a bunch ofsmaller quakes that can increase inintensity and go back down.”Scientists have no way of knowing how long theswarm will last, thoughthe one in 1985 went on for months. Over eight days,more than 1,270mostly tiny earthquakes have struck between Old Faithful andWestYellowstone. The strongest dozen or so have ranged between magnitudes3.0and 3.8. The largest quakes in the current swarm have included twoof magnitude3.1 and one of magnitude 3.0 late Sunday and early Monday.Relatively mundanefault slippage is believed to be causing the latestquakes. [Other quakesMonday - 2.9, 2.9, 2.8, 2.6 /Tuesday - 2.6 / thismorning 2.7, 2.8, 3.1]
ECUADOR- Tungurahuavolcano has been erupting ash for the past several weeks, but thethickclouds of the eastern Andes obscured most of the activity. A break intheclouds enabled the Moderate Resolution Imaging Spectroradiometeraboard NASA’sTerra satellite to observe the eruption on January 23. Atan ash plumestretched 60 km (40 miles) to the southwest of the peak.Ash reached analtitude of 27,000 feet (8,200 meters) - more than 3,000m (10,000 ft) abovethe 5023 m (16,480 ft) summit. Observers from theEcuadorian InstitutoGeofísico reported lava fountains and lava blockscascading down the flanks ofthe volcano, as well as loud booms andashfall in the surrounding communities.
