ECUADOR - Tungurahua volcano

July 8th, 2010
As of the 25th of June, the Instituto Geofísico-Escuela Politécnica Nacional (IG) has reported that Reventador volcano continues presenting/displaying moderate levels of eruptive activity characterized by the occurrence of a small small volcanic dispersion volume and of earthquakes of volcanic origin. A total of 10 seismic movements of long period (LP) were entered, 9 explosions, 2 episodes of spasmodic tremor.
........
Following the explosions one noticed episodes of tremor to which noises and roars were associated type exhalation of median to strong. Sometimes, between clouds it was possible to be observed volcanic gas and aqueous vapour emissions with low loads moderate of ash that went to the West and the Southwest of the volcano. It was received reports of fine ash falls of white colour along with drizzles in Chonglotus, during this behind schedule. Light rains in all the western flank of the volcano without generating lahars or flows of mud were registered. On 2 June a pyroclastic flow traveled 1.5 km down the NW flank. Tungurahua is a steep-sided stratovolcano or a conical volcano composed of many layers of hardened lava, tephra, and volcanic ash and is located near Ecuador's fourth largest city of Ambato, some 140 km south of the capital Quito.

Is er al meer bekend over Yellowstone?

En de vulkaan in Napoli begint ook al te borellen ?

Zullen wij dan de Generatie zijn die een Vei 7 of Vei 8 uitbarsting mee gaan maken?

yes we gaan weer dood Je zal maar net aan het rukken zijn als een pyroclastische wolk over je heen rolt.. Echt lullig als men je dan 2000 jaar later met je lul in je hand opgraaft..

Lake Taupo... a giant timebomb...
Beneath the waters of Lake Taupo lies one of the world's biggest volcanoes and scientists say an eruption would be one of the most life threatening events New Zealand has ever faced.

They say an eruption involving New Zealand's largest lake would dwarf the trouble caused by the 1995 Ruapehu eruption and lahar flows since then.

"Taupo on a global scale is a very large volcano. ]b\The crater is somewhere in the order of 15 and 20 kilometres in diameter[/b], so it's right up there in the top ten globally for size," said volcanologist Brad Scott.

Other experts think it could even eclipse the worldwide disruption caused by the Icelandic volcano three months ago.

"We know that the North Island would be pretty heavily damaged and everything would be affected, basically starting with the airplanes," said volcanologist Nico Fournier.

But scientists say that there will be plenty of warning signs before the big bang including more frequent earthquakes, hot springs around Taupo drying up and the lake could start bubbling.

Fournier says scientists are always on alert, monitoring the lake 24 hours a day, seven days a week.

"We know the volcano is still doing things, but it's not yet fully understood. It's something we're actually doing research on at the moment to see if it really is the volcano acting up a bit," Fournier said.

The Taupo volcanic zone is one of the most active in the world. There are 12 active volcnoes and at least 30 geothermal hot spots that stretch from Mount Ruapehu to White Island.

"We have people living on or playing on those volcanoes almost every day, like the skifields at Ruapehu and the tourism at White Island, so we definitely pay a lot of attention to those in the short term. But we treat the Taupos equally the same," says Scott.

Peter Lechner from the Civil Aviation Authority says in the event of Taupo erupting, shutting airports is dependent on the degree of the volcanic fallout.

"The eruptions we've seen so far not a big problem, if we had a massive eruption out of Taupo, I don't think aviation would be operating much at all," he said.

Phil Parker from the Civil defence says New Zealand is not well prepared to deal with an eruption.

"People may need to self evacuate because we don't have the personnel to evacuate everybody. We rely heavily on people doing it themselves," he says.

Taupo erupts every 900 years on average, and the last big bang was 1700 years ago. Scientists say it's not a matter of if, but when.

Lava from Kilauea Volcano threatens home
Lava oozing from Kilauea Volcano forced the evacuation of a Kalapana couple and their dogs yesterday and closed within 100 yards of their house — one day after the flow crossed the Big Island's Kalapana access road and enveloped the intersection of Highways 130 and 137, sending up a plume of thick, black smoke.

The couple's two-story home is now landlocked by cooling lava as hotter, more destructive lava inches closer, Big Island Civil Defense Director Quince Mento said yesterday.

He declined to speculate on whether the home would be lost. "When you're dealing with Madame Pele, you don't want to take anything for granted," Mento said. "Things change. They can turn on a dime."

At least four other homes are in the area, but none is immediately threatened, said Mento, who has been driving to Kalapana every day to survey the lava's path.

For people who live in Kalapana, volcanic activity is part of daily life. "If you live there," Mento said, "you're aware of the risks."

The owner of the house in immediate danger had been surveying his property every day until county officials urged the couple to evacuate, Mento said.

The homeowners remain upbeat, even though they realize their house could go up in flames.

"It's unfortunate -- you feel very bad for them," Mento said. "But there's always hope that it could stop."

On May 21, Kilauea Volcano saw its 10,000th straight day of activity, making it the world's longest continuously erupting volcano.

Puu Oo -- or Kilauea's east rift zone vent -- started gurgling on Jan. 3, 1983, and a summit vent on Halemaumau Crater has been erupting since March 19, 2008.

Lava began marching onto the Kalapana access road around midnight Saturday, then took out the intersection of Highways 130 and 137 around 7 a.m. Saturday.

A crowd of "well over 1,000" people continues to stand watch 24 hours a day, even though the previous viewing area was destroyed on Saturday.

"It's now under a couple of feet of lava," Mento said.

The U.S. Geological Survey's Hawaiian Volcano Observatory posted photos that show lava burning through thick vegetation and covering about 300 yards of highway asphalt.

Earlier in the week, Jim Kauahikaua, scientist-in-charge at the U.S. Geological Survey's Hawaiian Volcano Observatory, wrote that "a circulating lava pond deep in the collapse pit within the floor of Halemaumau Crater" was visible via webcam, and three earthquakes with magnitudes of 2.9 and 3.0 were recorded below the Big Island.
