Chile’s Puyehue volcano spews lava
Lava has begun spilling from Chile’s Puyehue volcano, 18 days after it first erupted, but there’s no danger to nearby residents, according to the National Service of Geology and Mining.
But the ash cloud created by the eruption continues to wreak havoc on airlines around the world.
The Chilean airline LAN cancelled flights to Temuco and Valdivia in the south of the country, and a number of flights were suspended in Australia and New Zealand.
“Viscous lava has flowed slowly westward in a channel roughly 50 metres wide and 100 metres long,” the national geology service known as SERNAGEOMIN said in its latest report.
Last week, SERNAGEOMIN chief Enrique Valdivieso said the appearance of lava would signal Read more…
Argentine towns suffer under falling volcanic ash
Divers of the Prefectura Naval Argentina inspect the Rio Limay covered with ash from Chile's Puyehue-Cordon Caulle volcano chain at the mountain resort of San Carlos de Bariloche in Argentina's Patagonia June 16, 2011. Some towns in Argentina's Patagonia remain blanketed in volcanic ash. Airline activity is getting back to normal after days of chaos caused by a towering ash cloud, but Andean towns are covered in a thick, ashed blanket that is disrupting water and power supplies and raising fears over the key winter ski season that starts next month.
BUENOS AIRES, Argentina (AP) — The government of one province in Argentina declared an economic emergency on Thursday to aid towns where falling ash from Chile’s erupting volcano is endangering livestock and keeping tourists away.
The emergency in Neuquen province follows a similar measure by the national government in other parts of Patagonia where agriculture has been hit by accumulating volcanic ash.
The decree by Gov. Jorge Sapag will mean that those affected can receive tax benefits, among other measures.
Chile’s Cordon Caulle volcano began erupting June 4, spewing ash that has disrupted flights in countries ranging from Uruguay to Australia.
The ash has also blanketed towns across the border in Argentina. In the area of Villa La Angostura, located 24 miles (38 kilometers) from the volcano, up to one foot (30 centimeters) of ash has accumulated on the ground.
The ash has made it difficult to drive safely on roads, and the eruption came Read more…
Shiveluch volcano erupts in northern Russia
A volcano in northern Russia has erupted, and is churning out ash to a height of 10,000 metres, scientists said on Friday. The 3,283-metre Shiveluch volcano increased activity in May 2009 and has been periodically spewing ash from three to eight kilometres. “Low clouds prevent us from getting a clear visual of the event, but our seismic data indicates that Shiveluch has churned out ash plumes to a height of up to 10,000 metres,” said an official at the Far Eastern Institute of Volcanology and Seismology.
Scientists said that the volcanic activity over the past two-three years has altered the contour of the volcano, with the crater increasing in size by nearly 50% and the slopes becoming far steeper than before.
The current eruption poses no immediate threat to nearby settlements. But the ash fallouts could be hazardous to health and the environment.
Ash Cloud Spreads From Erupting Nabro Volcano In Eritrea
The Anabro (Nabro) volcano in the Northern Red Sea Region of Eritrea has erupted sending an ash plume more than 13.5 kilometres into the sky and disrupting air traffic across eastern Africa.
Part of the Afar Triangle, the stratovolcano is one of many volcanic caldera complexes in the north easternmost part of the East African Rift valley region. Nabro is located in the Danakil Depression, close to Eritrea’s border with Ethiopia and north of Djibouti, and has not erupted in at least 150 years. It is the most prominent of 3 large volcanoes (Nabro, Dubbi, Mallahle) in the region, each containing a large summit caldera.
The volcano erupted at 2103 GMT Sunday evening. The Volcanic Ash Advisory Center (VAAC) said Monday that the 5,331 ft volcano has resulted in a large ash plume of up to 13.5 kilometres (8 miles) high. The scale of the eruption, compared to the ongoing eruption in Chile and 2010′s eruption at Eyjafjallajökull in Read more…
Hawaii Volcano May Overflow As Lava Levels Rise
Rising lava levels at the Kilauea volcano in Hawaii are being monitored closely by scientists.
Video released by the US Geological Survey showed a stream of orange molten rock gathering at the volcano’s Halema’uma’u vent.
It represents a natural phenomena scientists call a pyroclastic flow, with lava surging into a lake where temperatures can rise as high as 700C.
The lake, which is believed to have formed in the later part of 2009, has been reported to resemble an above-ground swimming pool.
But there are concerns the lava level could overflow the rim – while there was also new activity at the Puu Oo crater, which appeared to be draining lava until recently.
Something Strange With Volcano Eruption in Chile
What appears to be an enormous ash cloud rising from the eruption of a long dormant volcano named Puyehue in southern Chile on June 4, 2011, isn’t quite matching up with the location of the recorded earthquakes today in the immediate area.
“The Cordon Caulle (volcanic range) has entered an eruptive process, with an explosion resulting in a 10-kilometer-high gas column,” Chilean state emergency office said.
The thing is, for some unknown reason, as of this writing, eight earthquakes near magnitude 5 have shook the earth near the Puyehue volcano. The problem is, the earthquakes are located 20 to 40 miles away from the eruption! Very Strange Indeed. (Strange because one would think that Read more…
Volcano expert fears we’ll see a super eruption
Volcanologist Clive Oppenheimer yesterday warned there was a one-in-500 chance of the world being hit by a super- volcano this century.
The reader in vulcanology at Cambridge University told a Hay audience: “That might not sound like much, but it is a lot more likely than an asteroid impact.
“The events in Japan remind us that you can have a tsunami and earthquake and a nuclear plant there as well and you can have these chain reaction events that are actually quite calamitous and they are not unimaginable.”
Examining geological, historical and archeological records, the expert took the audience on a journey back to three volcanic eruptions that have shaken the world – the 1815 Tambora volcano in Indonesia that Read more…
Kilauea crater lava lake grows
A raised lava lake, described by volcano scientists as looking “somewhat like an above-ground swimming pool,” has been building since lava returned to Pu‘u ‘O‘o crater in March, scientists from the Hawaiian Volcano Observatory reported.
The rim of the raised lava lake was about Read more…
115 quakes recorded at Taal volcano in 24 hours
MANILA, Philippines— (UPDATE) Taal Volcano was rocked by 115 earthquakes in the past 24 hours, the highest number of tremors recorded in the area since the Philippine Institute of Volcanology and Seismology placed the restive volcano under Alert Level 2 last April.
It was the highest number in a day, a jump from the average of 10 mild quakes daily since alert level 2 (increasing restiveness) was hoisted over Taal on April 9, said Jaime Sincioco, officer-in-charge of the Volcano Monitoring and Eruption Prediction Division of Phivolcs, in a phone interview.
He said that in the series of the 115 volcanic quakes recorded up to 3 a.m. Monday, 12 were of intensity 1 to 4 and “were felt by the residents” on the volcano island.
The strongest quake, also since April 9, was felt at intensity 4 at around 1:05 a.m.
Phivolcs said residents around the volcano in Taal, Batangas heard rumbling Read more…
