Sinabung Volcano, Indonesia - John Seach
Posted by John Seach
Volcanic activity Sinabung volcano, Indonesia has decreased based on seismic observations, deformation, SO2 concentration, and visual observations. The alert status at Sinabung has been decreased from CAUTION (Level IV) to alert (Level III) effective from 23 September 2010 at 3:50 pm. Activity began at Sinabung volcano, on 27th August 2010 after 400 years of inactivity. Six large explosive eruptions have occurred at the volcano in the past month. These eruptions occurred on August 27 at 18:30 pm, August 29 at 0:10 pm, August 30 at 06: 23 pm, September 03 at 04:38 and 17:59 pm, and September 7, at 0:23:37 pm. The largest explosive eruption occurred on September 7. Eruption was accompanied by strong roar and rattled windows 8km from the volcano. An eruption column 5000 m high drifted southeast. As of September 22, 2010, activity was dominated by thick white gas emission, rising an average height of between 50-100 m above the crater. A lahar hazard remains at the volcano. Most residents are permitted to return to their homes and resume normal activities. Because of the ongoing risk of phreatic eruptions, people are advised to stay at least 3.5 km from the crater, and this includes three villages.

Piton de la Fournaise Volcano, Reunion
High levels of seismicity continues at Piton de la Fournaise Volcano, Reunion. On 29th September 33 earthquakes were measured. The magnitude of the largest earthquake was 1.7 (not felt by the population). A significant number of landslides have occurred at Dolomieu crater (33/day) with an average volume significantly higher compared to previous days. Inflation of the edifice of Piton de la Fournaise has occurred particularly its eastern portion. An increase in summit crater fumaroles has been observed.

Volcano on Reunion Island erupts

Officials on Reunion Island in the Indian Ocean say the Piton de la Fournaise volcano has erupted.

The prefecture on the French island said the volcano erupted Thursday at 7:10 p.m. local time (1510 GMT) following several days of heightened seismic activity.

The prefecture says in a statement the lava flow appeared stable, but access to the volcano and its surroundings has been indefinitely restricted.

The volcano is located in the southeast of the island. Most of the main population centers, including the capital, Saint-Denis, are clustered on the other half of the island.

The Piton de la Fournaise is a very active volcano and it often spews fumes and lava.

Krakatau erupts also
Indonesia's Anak Krakatau volcano in Sunda Strait, straddling East Java and Sumatra, has spewed ash and flaming rocks.

Officials raised alert levels to 'high' on Friday as the volcano showed signs of increased activity, producing 117 small eruptions.

Staff at the observation post in Pasauran, Banten Province are on a 24-hour watch. Residents in Pasauran have been told to stay at least two kilometres away from the volcano.

Anak Krakatau means 'Child of Krakatau', named so because it rose in the place of Krakatoa volcano after it blew itself apart in one of the most destructive eruptions in history in 1883. The area is a popular tourist site and many villagers farm on the slopes of nearby Ibu Krakatau (Mother of Krakatau) on the same island.

"Until now we are still on alert level but when we examined our equipment on October 27 and 28 we experienced tremors," said Anton Priambudi, a volcanologist observing Anak Krakatau.

Several volcanos in Indonesia increased their activities recently following Mount Merapi's eruption on Tuesday.

The eruptions came only a day after a tsunami struck the remote islands in western Indonesia.

Bulusan volcano increases activity
MANILA, Philippines The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded Sunday increased seismic activity at Bulusan Volcano in Sorsogon province, 24 hours after the active volcano spewed a 600-meter ash column and grayish steam last Saturday.

State volcanologists noted that at least 10 volcanic earthquakes and four explosion-type events have been documented subsequent to the emission of ash and steam at 8 a.m. on Saturday.

After the ash ejection (last Saturday), steaming activity was characterized by strong emission of white steam column that reached a maximum height of 200 meters above the crater rim, Phivolcs said.

Since 2 p.m. on Saturday, visual monitoring of the volcano's other activities were being obscured by thick clouds covering the volcano's summit.

Phivolcs maintains the status of Bulusan Volcano under Alert Level 1 (rendering abnormal activity) due to its current activity that may lead to more steam and ash ejections in the coming days.

It reminded the public not to enter the four-kilometer permanent danger zone from the volcano.

People residing near the valleys and streams were also advised to be extra alert against sediment-laden stream flows in the event of heavy rains.

Bulusan Volcano is considered the 4th most active volcano in the country, after mounts Mayon, Taal, and Pinatubo. It has erupted 15 times since 1886.

Since the volcano showed intermittent signs of ash explosions and seismic activity in 2007, Phivolcs reported activity at Bulusan only last Saturday.

Bulusan spuugt opnieuw
De Filipijnse vulkaan Bulusan heeft opnieuw as gespuwd. In navolging van het drama met de Indonesische vulkaan Merapi beginnen de Filipijnen aan een evacuatie. Ongeveer 80.000 mensen wonen in het risicogebied.

De Filipijnse vulkaan ligt op ongeveer 3.000 kilometer van zijn Indonesische collega. Merapi eiste vorige week meer dan honderd dodelijke slachtoffers. Uit de 1.560 meter hoge krater van Bulusan stijgt een aswolk op.

Bulusan ligt op ongeveer 250 kilometer van de hoofdstad Manila. De laatste uitbarsting is nog maar van 2007 geleden.

ELEVEN volcanic earthquakes were recorded from 5 p.m. Tuesday up to 5 p.m. yesterday at Bulusan Volcano in Sorsogon.

Alert level 1 remains.

The Philippine Institute of Volcanology and Seismology reminded the public not to enter the four-kilometer permanent danger zone.

Phivolcs also said civil aviation authorities must advise pilots to avoid flying close to the volcano’s summit as ejected ash and volcanic fragments from sudden explosions may pose hazards to aircrafts.

Also, residents near valleys and streams were also advised to be vigilant against sediment-laden stream flows in case of heavy and continuous rains.

Residents were also warned of ash falls particularly at the northwest and southwest sectors of the volcano.

cienceDaily (Nov. 18, 2010) Months of volcanic restlessness preceded the eruptions this spring of Icelandic volcano Eyjafjallajökull, providing insight into what roused it from centuries of slumber.
An international team of researchers analyzed geophysical changes in the long-dormant volcano leading up to its eruptions in March and April 2010 that suggest that magma flowing beneath the volcano may have triggered its reawakening. Their study is published in the Nov. 18 issue of the journal Nature.
"Several months of unrest preceded the eruptions, with magma moving around downstairs in the plumbing and making noise in the form of earthquakes," says study co-author Kurt Feigl, a professor of geosciences at the University of Wisconsin-Madison. "By monitoring volcanoes, we can understand the processes that drive them to erupt."

Merapi Volcano, Indonesia
Eruptions continue at Merapi volcano, Indonesia with reduced intensity. Visual observations show white-grey emissions rising 1500 m above the summit. A total of 275 people have been killed in the eruption. A 20 km exclusion zone is in place around the volcano. Merapi remains at the highest level 4 alert. A threat of pyroclastic flows and lahars exists at the volcano.

Krakatau Volcano, Indonesia
Eruptions continue at Krakatau volcano, Indonesia. Explosions have been heard by people on the west coast of Java. Some residents at Anyer were concerned after they heard three explosions from Krakatau on Sunday. The number of explosion earthquakes increased to 933 on Friday. People are advised to stay more than 3 km from the volcano. Sea transportation has not been affected. Despite the explosions, the status of Krakatau remains at Waspada (Level 2).

Villagers flee Philippine volcano
Scores of people were forced to flee their homes after a restive Philippine volcano shot a column of ash into the air showering surrounding villages.
Residents of two villages near the 1565-metre Mount Bulusan volcano evacuated their homes after the volcano shot a column of ash some two kilometres into the air.

"The ones evacuated were those most vulnerable to the ash like the children, the elderly, the pregnant and nursing mothers," said disaster control chief Jose Lopez in an interview with ABS-CBN television.

Evacuees were taken to government schools that are being used as relief centres, he added.

More than 750 people have fled their homes since Bulusan started emitting ash on November 6, Mr Lopez said.

One man with asthma already died from Bulusan's ash emissions on November 11, the National Disaster Risk Reduction and Management Council said in Manila.

Government vulcanologists had earlier raised the alert level for Bulusan from zero to level 1, indicating abnormal activity, possibly a sign of more ash eruptions to come.

The government has warned people not to enter a four-kilometre "danger zone" around the volcano and communities nearby were told to be on alert for volcanic mudslides caused by heavy rains mixed with ash deposited on Bulusan's slopes.

Bulusan, 250 kilometres southeast of the capital Manila on the main island of Luzon, is one of the country's 23 active volcanos.

The local government said a quarter million people live in six towns around the volcano, and many of them could be at risk if the mild eruption increases in intensity.

Bulusan has erupted 16 times in recorded history, the last time in 2006. It began emitting ash again from November 6.

The Philippines is part of the Pacific Ring of Fire where frequent volcanic eruptions and earthquakes take place

Tungurahua triggert starke explosion[/url]

Panik unter der Bevölkerung
Nach fast fünf Monaten relativer Ruhe hat heute der Vulkan Tungurahu in Ecuador eine gewaltige Explosion erzeugt. Nach Angaben des Geophysikalischen Instituts von Ecuador wurde eine mehrere Kilometer hohe Aschewolke in die Atmosphäre geschleudert.

5.4 Magnitude Earthquake shakes Indonesia's supervolcanic lake, Lake Toba

Lake Toba is an Indonesian supervolcano with a lake on the crater, the supervolcano is 100 kilometres long and 35 kilometres wide. The deepest point of the volcano is 1,666ft. The supervolcano is located on the island of Sumatra that also suffered the worst in the 2004 earthquake. The lake on the volcano is the largest in Indonesia and the largest volcanic lake in the world.

Today Lake Toba suffered a 5.4 Magnitude earthquake, the earthquake was larger than normal tremors on the volcano. In history the eruption of Toba had global consequences, killing thousands. Once Lake Toba erupted and it led to a volcanic winter worldwide. (That theory is still debated today).

Renewed activity in Ecuador
Volcanic activity has been reported in the Tungurahua (Throat of Fire) volcano in Ecuador, the second case sighted in the past few weeks.

The volcano spewed molten rocks and large clouds of gas and ash near Banos, south of Quito, Reuters reporetd on Tuesday.

The Tungurahua's volcanic activity follows last month's eruption, when a column of gas shot up seven kilometers into the sky.

No casualties have been recorded so far, but flight re-direction is being considered.

Tungurahua is located approximately 150 kilometers southeast of Ecuador's capital, Quito.

After a long period of peaceful resting, the volcano erupted in 1999, leading to the evacuation of about 250,000 people.

In 2006, Tungurahua underwent another major eruption, leading to the death of seven villagers. Yet another major eruption took place in 2008, leading to more evacuations. The next eruptions occurred in May and in November 2010.

Tungurahua's eruptions are strombolian, or low-level eruptions. Following its 1999 eruption, the volcano continues its activity on a medium level.

Authorities order evacuations
BANOS, Ecuador, Dec 4, 2010 (AFP) - Authorities ordered the preventive evacuation Saturday in the southern Ecuadoran town of Bano as they put the country on high alert over a possible major eruption of the Tungurahua volcano.

"People are coming to safe areas in an orderly fashion," Deputy Interior Minister Edwin Jarrin told AFP.

The Geophysical Institute in Quito reported since early Saturday a "very rapid and sustained increase in seismic activity and other manifestations at the surface" of the volcano.

Tungurahua, which has been erupting off and on since 1999, was spewing out incandescent material and ash, according to the institute.

A red alert was in effect in Banos and other Andean villages of the 5,029-meter (16,500-foot) volcano, whose name means "throat of fire" in the local Quechua language. It is located some 135 kilometers (85 miles) south of Quito.

In 1999, the 15,000 inhabitants of this town were forcibly evacuated by a powerful eruption and were unable to return to their homes for a year.

Banos, one of the gateways to the Amazon jungle, hosts an average of a million tourists a year, 40 percent of them foreigners, according to local officials.

Tungurahua’s biggest eruption, in August 2006, left six people dead and destroyed hundreds of homes.

Eruptive Activity at Tungurahua Volcano Decreases

QUITO - The eruptive activity of the Ecuadorian Tungurahua volcano, located in the Tungurahua province, reduced its intensity while maintaining a constant column of ash.

The emission column, with a moderate to high contents of ash, reached about two miles above the crater and headed towards the east, although experts believe that it has reduced the danger to surrounding areas.

Incandescent blocks associated to the activity of the volcano of 1.029 meters of altitude roll down the flanks of the volcano.

As of Saturday afternoon, a decline of the intensity has been registered in the activity of this volcano which had earlier forced to declare a red alert and the evacuation of residents and tourists of nearby areas.

The Tungurahua, located south of Quito, has been active since 1999, according to director of the Geophysical Institute Hugo Yépez.

Volcano Erupts In Russian Far East, Massive Eruption Feared

VLADIVOSTOK, Dec 17 (Bernama) -- A volcano in the Russian Far East peninsula erupted several days ago, prompting experts to raise the hazard level caused by the possible massive eruption, reports China's Xinhua news agency on Friday.

The volcano Kizimen, located in the Kamchatka Peninsula, has spewed ashes as high as 10 km into sky and the western slope of the mountain has been covered with ashes due to high winds.

The snow on the slope was thawing quickly, pushing river water level up by 60 cm.

Specialists don't rule out the possibility of a massive eruption of Kizimen, which has remained dormant for 80 years.

A helicopter would soon be sent to the site to check whether the eruption was still going on.

The nearest human settlement is about 110 km away from the volcano.

The Kamchatka Peninsula has a high density of volcanoes, flanked by large volcanic belts containing about 160 volcanoes, with 29 of them still active.

Fuego, Guatemala rumbling, building up for ... ?
One of Guatemala's active volcanoes, Fuego, is rumbling at a greater-than-usual rate, the emergency services office said Saturday.
The volcano is seeing 12-15 small explosive events per hour, the office said, citing a report from the National Seismological Institute.

Fuego is belching ash to heights of 500-900 meters and ash has been seen in the cities of Antigua Guatemala and San Juan Alotenango, the office said.

At 3,763 meters (12,345 feet) above sea level, Fuego sprawls across three departments of the Central American nation: Sacatepequez, Escuintla and Chimaltenango.

In May, the Pacaya volcano in Escuintla department spewed ash over much of the country

Mount Krakatau ash clouds reach up to two kilometers

ANYER - The height of the ash clouds that are currently being emitted by the Mount Krakatau volcano is still increasing and reaches almost up to two kilometers now. The volcano, located in the Sunda Strait between the islands of Java and Sumatra, also shows an increase in the amount of tremors inside the belly of the volcano.

Based on visual observations of the volcano, ash clouds now reach up to 1.700 meters and above, higher than in the past few days. This was reported by the head of the observation post for the Krakatau volcano in the village of Pasauran in Serang, Banten province, Anton S. Pambudi. He also said that the higher ash cloud was due to increased activity inside the volcano.

The Agency for Volcanology and Geological Disasters PVMBG is maintaining the alert status of the volcano for the time being; level two. People near the volcano are not allowed to come close to the crater of the volcano. There is a chance that volcanic material falls from the sku in the area. The Mount Krakatau volcano often emits small stones that fall down on it's slopes.

Etna active - no lava yet
Mount Etna in Sicily has once again become active erupting large amounts of ash, reported Monday Italian National Institute of Geophysics and Volcanology.

Seismologists have recorded the eruption of volcano at Mount Etna and say that it is accompanied by the ejection of volcanic ‘bombs’ (large stones) and the large amount of ash in the area southeast of the crater on Monday night.

The most active emissions for duration ranging from one to three minutes occurred between midnight and two o’clock in the morning. These large volcanic ‘bombs’ reached a height of several tens of meters over the crater. By around 06.00 am the volcanic activity decreased significantly, but not stopped completely.

However, no eruption of lava has been recorded from the crater of Mount Etna, said experts from National Institute of Geophysics and Volcanology lab, located in the city of Catania.
