Nyamulagira
eklemetti | August 31, 2010Busy ... so busy! I'll try to have more later today but the next 24 hours for me are super duper busy.
However, I did want to pass along some news that was noticed by the Volcanism Blog that a volcano at Virunga National Park in the Congo erupted overnight. Now, I haven't been able to find much information beyond the single report in the Irish Independent - and that report doesn't even specify what volcano is doing the erupting - Nyamuragira or Nyiragongo. However, we've seen eruptions at the park earlier this year so the volcanoes are almost constantly degassing, so this should be a surprise…
eklemetti | February 4, 2010News!
Pakistan is home to the world's tallest mud volcano in the region of Balochistan - and its somewhat near the reports of an "eruption" earlier this week.
Guess what? Since Wednesday evening, seismicity at Yellowstone has dropped precipitously. The last batch of earthquakes on February 3rd were also back to deeper levels - 8-9 km depth - compared to the potential shallowing earlier in the week. I'm sure the caldera will keep us on our toes, but as of now, it seems to have settled down a bit.
Over in Pakistan, there is mounting evidence that the recent "volcanic" eruption reported as, in…
eklemetti | January 20, 2010This week's USGS/Smithsonian GVP Volcano Update!
Highlights include:
A volcano I had never heard of in the Kuril islands is showing signs of life: Kharimkotan. Satellite images show a thermal anomaly at the summit of the volcano - its last known eruption was in 1933.
Ash, sulfur dioxide and steam continue to erupt from Nyamuragira in the Congo, although lava flows have abated.
Crater C at Arenal had sporadic strombolian activity - which is par for the course for the Costa Rican volcano.
I must have missed this, but since December 14, the ash erupted at Gaua in Vanuatu has become denser and…
eklemetti | January 14, 2010The weekly volcano report, brought to you by our friends at the Smithsonian Global Volcanism Program and the U.S. Geological Survey.
Highlights (not including Mayon, Nyamuragira and Turrialba):
Eruptions continue at Piton de la Fournaise on Reunion Island - heck, this would be the volcano news if it wasn't for all these other, more explosive systems getting in the way. Lava fountains, flows and pools were the order of the day in the SW Dolomieu crater until the 12th of January.
Chaiten in Chile continues to chug along - block-and-ash flows were seen and ash plumes continue to emanate from the…
eklemetti | January 13, 2010Somehow I haven't posted a bunch of interesting items collected over the last few weeks, so I need to catch up. A pre-emptive hat tip to everyone who has sent me links or notes that might seem familiar in this post.
Tungurahua in Ecuador erupting in 2000.
First off, those of you looking for information on the Haitian earthquake that devastated the capitol Port Au Prince, Highly Allochthonous has post on the tectonics of the quake. Right now, it is hard for me to come up with a worse location in terms of devastation for a quake to have hit in the Caribbean Basin.
Back in volcano news, a lot of…
eklemetti | January 6, 2010Two volcanoes down, two volcanoes up!
Fire fountain on Nyamuragira in the Congo, January 2010.
DownMayonActivity at Mayon has continues to drop - although PHIVOLCS warns that an eruption could happen at any moment and without much warning. About a quarter of the evacuated families have no returned home since PHIVOLCS gave the OK to return home on January 2 - but Philippine officials are still on alert in case evacuations have to be reinstated.
Redoubt
The resurgent Redoubt is no long ... er ... resurging? AVO lowered the alert status to Green - meaning normal/background levels of activity.…
eklemetti | January 3, 2010A pile of news for the new week!

MayonPHIVOLCS may lower the alert status at Mayon to Level 2 after almost a week of lower seismicity and no ash explosions since December 29th. Schools that were being used as evacuation centers were also returned to teachers and students for the start of classes after the Christmas holiday. However, the Albay provincial government is now considering a plan to permanently move everyone who lives within the 6-km danger zone around Mayon, even if…
