quote:February 21, 2011 MANILA, Philippines Hundreds of villagers fled to safety Monday after a restive volcano belched ash and smoke into the sky after a monthlong lull, officials said. Despite Mount Bulusans ash explosion, its 13th since November, there were no signs of an imminent eruption involving magma pushing out of the cone, said government chief volcanologist Renato Solidum. The huge plume of grayish smoke shot up to more than a mile (2 kilometers) toward the blue sky, with the ash drifting southwest toward four farming towns in Sorsogon province, where about 1,200 villagers fled to emergency shelters and houses of relatives, said Benito Ramos, who heads the governments disaster-response agency. Army trucks helped villagers move from communities hit by the ashfall and emergency teams handed out protective masks, Ramos said. There have not been any government orders to evacuate communities near the mountain. While many scrambled to safety, residents streamed out of houses in Irosin town to gaze or take pictures of the mid-morning spectacle using their cellphones. Still-hot debris at the peak of Bulusan, one of the countrys 23 active volcanoes, came into contact with water, sparking the explosion. Such steam-driven blasts have happened since November and could continue in coming weeks, Solidum said. -Macon.com Star

quote:Mt Baker: Eruption is overdue...
Cloaked in snow and visible across the U.S. border from Vancouver, Mount Baker looks like a gentle giant.
But volcanologist Mark Jellinek, at the University of British Columbia, says Mount Baker, located in Washington state, is probably overdue for an eruption -an explosion he and his colleagues hope to predict well in advance based on the how much "wagging" goes on inside the volcano as magma rises up from the deep.
According to their research, to be published Thursday in the journal Nature, volcanoes shake and vibrate in distinct and predictable ways when they are going to blow because giant columns of magma "wag" back and forth inside them.
"It's basically like a dog wagging its tail," says Jellinek, except that the magma columns are up to a kilometre high.
They are so powerful they shake mountains and when they blow they can hurl hot ash up to 40 kilometres into the atmosphere, with sometimes devastating impact as the ash spreads across surrounding areas. (Vancouver is far enough from Mount Baker it will be spared the worst effect, though Jellinek says he expects the city could be covered in a thick layer of fine ash. "It would make a huge mess," he says.)
It has long been known that volcanoes vibrate at pretty much the same frequency before they explode, whether they are in B.C., Alaska, the Caribbean or the Philippines. But until now no one has been able to explain why volcanoes that are so different in size and character behave in the same way.
"Magma wagging" is the most plausible explanation yet, and may help forecast deadly eruptions, say Jellinek and David Bercovici from Yale University and co-author of the new study.
Their model of the "magma wagging" explains why tremors in nearly all explosive volcanoes stay in a narrow band of frequencies that can be felt but are so high humans can't hear them. Just before and during eruptions, the frequency climbs to a higher pitch, and the range spreads out.
It provides "a fundamental mechanism for tremor that is generic to nearly all volcanically explosive systems," the researchers report.
As Bercovici put it, the shaking is both a warning "and a vital clue about what is going on in the belly of the beast."
There can be weeks to months of warning before volcanoes erupt but some come to life quickly. "The most recent eruption in the Aleutians in Alaska had five hours notice," says Jellinek. "But in general we do better than that."

quote:Eruptions continue at Fuego volcano, Guatemala. During the night incandescent explosions ejected lava 100 m above the crater and sent avalanches down surrounding valleys. Rumbling sounds were heard and audible degassing lasted up to six minutes at a time. Ash emissions reached a height of 800 m above the crater and drifted south and southwest.
Onrustig in Guatemalaquote:On 3rd March 2011 an explosion occurred from Caliente crater at Santa Maria volcano in Guatemala. Ash emissions reached 10,800 ft above sea level and produced ashfall in towns to the west and southwest of the volcano. The explosion generated a pyroclastic flow which moved 2.5 km down the southwest flank. Activity continued on 4th March with moderate explosions ejecting ash to a height of 11,000 ft above sea level, and ash fall on surrounding farms.
Mt Ruapehu wikiquote:Mt Ruapehu (NewZealand) is heating up
Mount Ruapehu is heating up -- but there's no need to panic, a volcanologist says.
Ruapehu's Crater Lake has reached 40degC, the third-highest temperature recorded at the lake since 2002.
Other signs, including gas output, minor seismic activity and changes in lake chemistry were also typical of a volcano in a heating cycle, GeoNet vulcanologist Tony Hurst said.
Ruapehu entered its current heating cycle last October, the eighth since the lake was re-established in 2002 after the 1995-1996 eruptions.
Ruapehu is on volcanic alert level one, which indicates signs of volcano unrest, but Mr Hurst told NZPA that was normal for an active volcano such as Ruapehu.
The colour of the lake might change and steam might be seen wafting off it if sediments on the lake floor were disturbed by increasing gas and heat flows into the lake, he said.
Scientists would continue to monitor the situation.
At 2797m, Ruapehu is the highest mountain in the North Island, and the most recent of the North Island volcanoes to have erupted.
quote:Four volcanic quakes at Mayon volcano
At least four volcanic quakes and moderate steaming were noted at Mayon Volcano in Albay in the last 24 hours, state volcanologists said on Wednesday.
The Philippine Institute of Volcanology and Seismology (Phivolcs) also said a fair crater glow can be seen by the naked eye Tuesday night.
"The seismic network around Mayon Volcano recorded four volcanic earthquakes during the past 24 hours. Steaming activity from the crater was moderate with white steam clouds drifting towards northwest. Fair crater glow (Intensity II- can be seen by naked eye) was observed last night," it said.
Phivolcs said Alert Level 1 remains in effect over Mayon Volcano, reminding the public not to enter the six-kilometer permanent danger zone (PDZ).
It cited the continuing threat from sudden small explosions and rockfalls from the upper and middle slopes of the volcano.
"Active stream/river channels and those perennially identified as lahar prone areas in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall," Phivolcs added.
In Sorsogon, Phivolcs recorded two volcanic quakes and three rockfall events from Bulusan Volcano in the last 24 hours.
Steaming activity at Bulusan's thermal vents was "wispy to weak" while no steaming was observed at the summit crater.
Meanwhile, Taal Volcano in Batangas remained relatively quiet, registering no volcanic quake in the last 24 hours.
Alert Level 1 also remained over Bulusan and Taal
quote:Volcano in eastern Indonesia erupts, spews gas cloud
JAKARTA, Indonesia — One of Indonesia's most active volcanos has erupted, sending lava and searing gas clouds tumbling down its slopes.
Volcanology official Agus Budianto said Friday that authorities were still trying to evacuate residents living along the slopes of Mount Karangetang.
There were no immediate reports of injuries or serious damage.
The 5,853-foot (1,784-meter) mountain is located on Siau, part of the Sulawesi island chain. It last erupted in August, killing four people.
Indonesia, the world's largest archipelago, is located on the so-called Pacific "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.
The eruption happened hours after a massive earthquake in Japan that triggered a Pacific-wide tsunami.

Het Volcanic Ash Advisory Center in Tokyo meldt wel een mogelijke uitbarsting van de vulkaan Sakurajima op 11 maart 2011 om 12:32 UTC. Met daarbij de melding dat ze de satelietbeelden gaan bekijken, en dat als daar as op is te zien ze wel weer een melding geven. Die nieuwe melding is er nog steeds niet, dus ik denk dat er geen uitbarsting is. Andere optie is dat het sinds die mogelijke uitbarsting nog te donker was om iets te zien en dat ze moesten wachten op daglicht. In dat geval zal het niet zo lang meer duren voor er meer duidelijkheid komt. (Japan zit op UTC+09:00)quote:Op vrijdag 11 maart 2011 22:42 schreef kahaarin het volgende:

Real of ook een hoax?quote:Japan Earthquake Triggered Volcano Eruption In Russia?
March 11, 2011 in Earthquakes, Volcanoes.
The major earthquake that hit Japan today may have just triggered some volcanoes in Russia as well. While reports are still vague on the incident, there is a strong correlation between the two occurrences. In Russia, there are reports that earthquakes where felt during the eruption.
According to dziennik pl world (translated):
In the Russian Far East, there has been a strong volcanic eruption. The air got a great cloud of volcanic dust, which can pose a threat to air traffic in the region.
Local experts warn that, dust can rise up to a height of seven kilometers.
Explosions were accompanied by minor earthquakes. Russian service monitoring the activity of cones, however, ensure that the implemented measures guarantee the safety of residents of neighboring towns.
According to Russian media reports, the first cloud of dust covered the city of Ust-Kamczatsk. Over five thousand people are forced to stay at home. The authorities have recommended the strict ban on opening windows.
The population, however, was not evacuated, and experts say that the dust does not constitute a great danger. Despite this, from Thursday, all offices of state institutions and organizations have suspended work – except in cases of emergency. For some time, also closed roads in the region.
While this eruption does not seem to be a significant threat to the people in Russia, the fact that an earthquake in Japan could have triggered a volcano eruption in Russia does have some significance.

quote:Vulkaan in zuiden van Japan wordt aktief
Na een zware aardbeving, een verwoestende tsunami en problemen bij een kerncentrale, staat Japan nu nog een probleem te wachten. In het zuidwesten van het land is een vulkaan actief geworden.
De vulkaan hield zich de afgelopen twee weken rustig maar begon vandaag weer met het spuwen van as en stenen. Die vlogen tot wel vier kilometer hoog de lucht in.
De activiteit van de vuurspuwende berg hoeft niet in verband te staan met de zware aardbeving van vrijdag. De ruim 1.400 meter hoge Shinmoedake is de afgelopen 52 jaar al bij vlagen actief. De berg is voorlopig ontruimd, omwonenden hoeven hun boeltje nog niet te pakken. (anp/gb)
Was net rustig daarquote:Japanese volcano re-awakens after few weeks
TOKYO -- The weather agency says a volcano in southern Japan is spewing ash and rock again as the country struggles with the aftermath of a catastrophic earthquake and tsunami in the north.
The Meteorological Agency issued a warning Sunday saying that Shinmoedake volcano resumed activity after a couple of quiet weeks.
The mountain is on Kyushu island, 950 miles (1,500 kilometers) from the epicenter of Friday's magnitude 8.9 earthquake and resulting tsunami, which devastated much of the country's northeastern coast.
It was unclear if the eruptions were linked to quake. Japan lies on the "Ring of Fire" - an arc of seismically active zones where earthquake and volcanic eruptions are common.

Baku, Fineko/abc.az. The Ministry for Emergency Situations of Azerbaijan informs that mud volcano Shihzeyirli located in Gobustan region erupted yesterday.
The Ministry reports that the eruption was accompanied by emissions of mud and fire that rose to a height of over 50 m. Currently, the eruption continues with less intensity. The height of emissions does not exceed 1-2 m. Deep cracks formed around the crater.
Ministry’s rescue services are operating in the area of eruption. At that, the eruption is reportedly not to pose any threat to the population or agriculture.

quote:Karangetang volcano spews again
Jakarta: At least 600 people have been evacuated to temporary shelters a day after Indonesian authorities issued a red alert for the Mount Karangetang volcano, a volcanologist said Saturday.
The volcano, located on Siau island off the coast of Sulawesi island, began spewing jets of hot clouds and lava Friday, prompting authorities to order the evacuations of three villages on its slopes.
Indonesia's chief volcanologist, Surono, said eruptions were continuing Saturday but there were no reports of casualties.
Surono's office Friday raised the alert level for the volcano two notches to the highest level after a series of eruptions.
'We have no choice but to order an evacuation because people were at risk of being affected by the hot clouds,' said Surono, who like many Indonesians uses one name.
He said 582 people had been moved to temporary shelters provided by the government.
Karangetang is one of Indonesia's most active volcanoes. Four people were killed during the volcano's eruptions in August last year.
Indonesia sits on the so-called Ring of Fire, an area known for frequent earthquakes and volcanic eruptions.
More than 300 people were killed in a series of eruptions at the Merapi volcano on Java island between October and November last year.
