James Bond volcano erupts

A Japanese volcano featured in the James Bond film You Only Live Twice has erupted covering surrounding villages with ash.

The Mount Shinomoedake volcano, in southern Japan erupted into life on Wednesday throwing ash almost 5,000ft into the air.

Roads have become unpassable and trains and flights to the area have been cancelled as officials assess the situation.

No injuries have been reported but a 1.2 mile safety exclusion zone has been created around the site.

The volcano has been active before, erupting in 1959, 1979 and most recently in 2008.

28th October 1966: The extensive film set at Pinewood studios, London, representing the interior of a volcano owned by the criminal syndicate SPECTRE built for the James Bond film 'You Only Live Twice' designed by Ken Adam, directed by Lewis Gilbert and produced by United Artists.

The film set of Bond villain Blofeld's volcanic lair at Pinewood studios, 1966

The volcano and surrounding area in southern Japan was used as the centrepiece for You Only Live Twice starring Sean Connery.

In the 1967 film, the then dormant volcano, had an artificial lake hiding the secret base of Bond nemesis Ernst Blofeld.

The volano interior was created by the iconic 1960s film set designer Sir Ken Adam and built at Pinewood Studios in England.

Residents temporarily evacuated their homes and transportation services were disrupted as smoke continued to billow from the erupting volcano Shinmoedake in the Kirishima range between Kagoshima and Miyazaki prefectures on Jan. 27. Plumes of smoke rose 2,000 meters following an eruption on Jan. 26, figures from the Kagoshima Local Meteorological Observatory showed. By 9 a.m. the following morning the smoke had fallen to an altitude of 400 meters, but officials said a series of small eruptions were continuing, and called for caution. "The volcanic activity has just started, so we can expect more periods of rest and activity. There's also a chance of a major eruption," an observatory representative said. The eruptions prompted some residents in Miyazaki Prefecture to temporarily evacuate their homes, while three junior and elementary schools in Miyakonojo, Miyazaki Prefecture, delayed the start of classes by one to two hours. In the Ojibaru district of Takaharu, a town in Miyazaki Prefecture located about 7 kilometers from the crater, 14 people voluntarily took shelter at a local health and welfare center in the predawn hours of Jan. 27. They returned to their homes later in the day. The eruptions forced the cancellation of services on the JR Nippo Main Line between Tano and Kokubu stations, on the Nichinan Line between Aoshima and Shibushi stations, and on the whole Kitto Line. A section of the Miyazaki Expressway also remained closed off due to poor visibility. On the evening of Jan. 26, after the volcano's eruption warning level was upgraded, the Kirishima Municipal Government in Kagoshima Prefecture closed mountain trail entrances within a 2 kilometer radius. It has asked residents to voluntarily avoid using other trail entrances.

Galeras volcano eruption expected

Colombian authorities have raised the risk level of the Galeras volcano to orange alert, meaning an eruption is likely within days or weeks.

The Colombian Institute of Geology and Mining (Ingeominas) declared the alert on the Galeras volcano in south-west Colombia Wednesday because of "fluctuating levels in the occurrence of seismicity," according to a statement issued by Ingeominas.

In particular, "the occurrence of earthquakes with screw-type characteristics, which are relevant because in Galeras they have been recorded in periods prior to eruptions," has caused the government agency to warn of an impending eruption.

The Civil Defense and Red Cross volunteers have prepared nine shelters with basic elements necessary for survival to accommodate the some 8,000 residents from the nearby municipalities of Pasto, Nari�o, and La Florida, the Director of the local Red Cross relief organization Javier Guerrero told RCN Radio. No residents have been evacuated yet.

Galeras is the country's most active volcano. It erupted in January 2010, forcing the evacuation of the area's inhabitants. In 2009 the volcano erupted five times.

Japanners ge�vacueerd om vulkaanuitbarsting

TOKIO - Honderden Japanners hebben maandag hun huizen moeten verlaten vanwege een vulkaanuitbarsting. De Shinmoedake spuwt as en rook duizenden meters de lucht in.

De mensen zijn opgevangen in scholen en gemeentehuizen, meldden de lokale autoriteiten.

In totaal moeten ruim 1150 mensen de gevarenzone verlaten. Een gebied van 3 kilometer rondom de vulkaan is ontruimd.

Reizen per trein of vliegtuig kan er niet meer. De straten in de buurt van de vulkaan zijn al bedekt met een laag grijze as.

De ruim 1400 meter hoge vulkaan ligt in het zuidwesten van Japan en is sinds woensdag actief. Het is 52 jaar geleden dat de vulkaan voor het laatst uitbarstte.

Taal volcano remains active, new quakes

Taal Volcano in Batangas showed heightened activity anew after at least 10 volcanic quakes around it were recorded in the last 24 hours.

In its 8 a.m. Wednesday bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) said the alert level at Taal remains at "1."

"Taal Volcano's status at Alert Level 1 means that a hazardous eruption is not imminent. However, the public is reminded that the Main Crater should be strictly off-limits due to sudden occurrence of steam explosions and accumulation of toxic gases," it said.

Phivolcs said the northern rim of the Volcano’s main crater – in the vicinity of Daang Kastila trail – may also be dangerous when increased steam emission is reactivated along existing fissures.

Phivolcs reminded the public that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended.

Mount Taal in de provincie Batangas van de Filipijnen is een van de gevaarlijkste vulkanen van Zuidoost-Azi�. Van deze vulkaan zijn meer dan 30 uitbarstingen bekend, waarbij veel slachtoffers gevallen zijn.
De vulkaan ligt op Vulcano Island in het Taalmeer. De vulkaan is een zogenaamde tufsteen-kegelvulkaan. Dit zijn steile kegelvormige vulkanen met een diepe wijde krater. De kegel is samengesteld uit dunne fijne stof. Het kratermeer van de vulkaan is 1,9 km in doorsnee, blauwgroen van kleur en maximaal 76 meter diep.
Sinds 1977 is de vulkaan niet meer uitgebarsten, maar sinds 1991 is hij wel diverse malen onrustig geweest.
Mount Taal is een van de 16 Decade Volcanoes die zijn aangewezen door de IAVCEI in verband met haar geschiedenis van grote uitbarstingen en de nabijgelegen bewoonde gebieden.

Mogelijke evacuatie na uitbarsting Shinmoedake

Shinmoedake, een vulkaan op zuidelijke eiland van Japan Kyushu is wederom uitgebarsten. De regering heeft nu ambtenaren naar het gebied gestuurd om een evacuatieplan op te zetten. De 1421 meter hoge vulkaan brak uit omstreeks 09.24 uur lokale tijd. Gisteren waren er ook al drie uitbarstingen. De uitbarsting zorgde ervoor dat er een aspluim gemeten werd van drie kilometer hoog. De aspluim trekt oost-noordoost richting Miyazaki.



Het Japanse meteorologisch instituut (JMA) heeft het niveau verhoogd naar level 3. Het meteorologisch instituut meldde er ook bij, dat een eventuele grote uitbarsting aanstaande is, wat ernstige gevolgen zou kunnen hebben voor de omringende woonwijken. Evacuaties worden uitgevoerd wanneer het alarmniveau een level 5 bereikt. Mocht er een grote uitbarsting gaan komen, dan is de overheid alvast voorbereid en zal het evacueren sneller verlopen.

De Shinmoedake vulkaan barstte voor het eerst sinds 52 jaar uit, op 27 januari, sindsdien is de vulkaan al meer dan 10 keer uitgebarsten. Autoriteiten hebben een "no go" zone van 4 kilometer ingesteld rond de vulkaan. Niet alleen de vulkaan Shinmoedake is actief in Japan, de 1117 meter hoge stratovulkaan Sakurajima, heeft ook een level 3 gekregen van het Japanse meteorologisch instituut. De vulkaan is ��n van de meeste actieve vulkanen van Japan. In 2010 kwamen er 1026 vulkanische incidenten voor, zoveel waren er sinds 1982 niet meer waargenomen.

Another Japanese Volcano Erupts

And another volcano has erupted in Japan.

Minami-dake crater at Sakurajima, a volcano on Japan's southern island of Kyushu, erupted Tuesday, following volcanic explosions at Mt. Kirishima in the same region.

The volcano spewed plumes of smoke and ash up to 2,000 meters into the air.
Local authorities temporarily banned citizens from driving near the area due to the sheer amount of ash raining down from the volcano.

Japan's Meteorological Agency says it will maintain a level 3 alert for Sakurajima that bans access to the mountain.

The agency notes, however, that it cannot confirm that this eruption was linked to a series of recent eruptions on the island.

New volcano images bij USGS - ongoing quakes a concern
A new spattering vent has formed on the south side of the Thanksgiving Eve Breakout shield, and the Hawaiian Volcano Observatory caught a glimpse of the activity just before daybreak on February 4.

The active Pu’u O’o crater floor is slowly filling the east side of the vent with lava.

Meanwhile, at Kilauea’s summit, the circulating lava lake in the collapse pit deep within the floor of Halema`uma`u Crater has been visible via Webcam throughout the past week. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

After this video was put together, the USGS gave this report on recent temblors in the region surrounding Kilauea. This statement was a part of Wednesday’s Kilauea Status Report, issued at 8:30 a.m. The report serves as a summary of the activity at the volcano over the last 24 hours.

“Nineteen earthquakes were strong enough to be located within Kilauea volcano” stated the update, prepared by HVO scientists, “sixteen within the upper east rift zone (starting beneath Puhimau Crater and migrating both uprift to Keanakako`i Crater and downrift to Hi`iaka Crater) and three scattered beneath a broad area extending both north and south of the upper east rift zone nearer Makaopuhi and Napau Craters; the ongoing seismicity within the upper east rift zone continues to be a concern.”

A small earthquake shook the town of Volcano on the Big Island this morning.

The magnitude 3.6 quake struck at about 8:30 a.m. and was centered about 4 miles south of Volcano at a depth of about 2.6 miles, according to the U.S. Geological Survey.

A magnitude 3.2 quake shook the same area yesterday at about 1:08 p.m., according to the USGS. Yesterday's quake was centered about 5 miles south-southwest of Volcano at a depth of 1.9 miles.

Earthquake swarm near Kilauea Volcano
HAWAII VOLCANOES NATIONAL PARK (HawaiiNewsNow) - Scientists at the Hawaiian Volcano Observatory on the Big Island of Hawaii are looking at a swarm of small earthquakes that shook Kilauea Volcano last week.

There were at least 42 earthquakes in the area within a 24 hour period that started Thursday. Geophysicists said while the temblors have diminished, they are another clue in what may come next at the world's most active volcano.

"Kilauea's summit has been extending, meaning that more magma is coming up to the summit than is going out to the east rift zone," said Jim Kauahikaua, the observatory's scientist in charge. That means there's move lava underground that's headed toward the actual Kilauea caldera, rather than the zone where most of the activity has been in the volcano's 28 year long eruption.

According to Kauahikaua, the extension of the crater has been going on for a few months.

"This extension of the summit is also reflected in the rise in lava in the Halemaumau vent," he said.

"All of them are indications that pressure is increasing in the magma chamber below the summit."

Besides spewing smoke and giving visitors a good show, the Halemaumau vent has served as a window to what's going on beneath the summit since it opened up about three years ago. Lava has been rising in the vent, and is now just 260 feet below the crater's surface.

While that's been going on, the east rift has remained active.

"There's also been increased activity within the Pu'u 'O'o crater," said Kauahikaua. "There are three different holes that emit lava at different times."

And that lava has been continuing through tubes toward Kalapana and the Kalapana Gardens Subdivision, slowly devouring homes there in the pats few months as the lava continues its slow crawl to the sea.

The eruption itself is showing no signs of stopping.

But the big question remains: Will there be even more lava at the summit vent?

"We're all wondering what it's going to do," Kauahikaua said. "It could rise high enough to the floor of Halemaumau and be visible to more people. It could drop out and all go to the east rift zone.

"We're all waiting to see what happens."

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

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."

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.

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

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.

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.

Real of ook een hoax?

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)

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.

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.
