eklemetti | April 18, 2010Some very quick notes on Eyjafjallajökull:
Eyjafjallajökull erupting at night on April 17/18, 2010, with impressive incandescent explosions.
European airlines are taking "test flights" to see the effect of the ash on their aircraft in hopes to convince EU officials to reopen airspace. Now, officials from KLM say that everything went fine in their test flight, but I haven't seen any details about flightplans, altitude and all the sorts of info you'd want to see if you want to believe these test flights are representative. However, the president of KLM does have a bit of a point in saying…
eklemetti | April 8, 2010The eruption at Eyjafjallajökull-Fimmvörduháls continues on - the explosive spatter and bomb eruptions at the new central vent (on the second fissure) were impressive all night, making the hikers/cars/aircraft look like mites in comparison. This eruption has, so far, followed the pattern of Hawaiian-style volcanism quite well, so I thought it could be a good time to talk about what exactly Hawaiian-style volcanism is. There is a sequence of events that leads up to and follows the start of an Hawaiian-style eruption - although this sequence can stop at any point along the way - but it is…
eklemetti | April 5, 2010Quick hits for a Monday morning (however, the week did have a good start).
Lava fountaining on March 27, 2010 at the Eyjafjallajokull-Fimmvörduháls eruption in Iceland.
The Eyjafjallajokull-Fimmvörduháls eruption is still going strong with two active fissure - and a lot of tourists poking around as well. If you watch the webcams closely, you can even see the cars and hikers trekking up near the erupting basaltic fissure (except today, as there seems to be a blizzard). Not to say that people are getting a little, well, nonchalant, but there is a story of serving meals cooked on lava up by…
eklemetti | March 31, 2010Superfast entry as I run out the door but ...
The new vent that opened on March 31 at Fimmvörðuhálsi in Iceland. The old vent is to the right in the image and new to the left. Image captured at 5:45PM EDT.
A second fissure has opened at the Fimmvörðuhálsi eruption in Iceland. Check out the webcam and you can clearly see a new set of vents (Icelandic - try Google Translate) on the left hand side of the image - and that wasn't there earlier today. You can see an image of the new vents here.
Thank you to all the Eruptions readers who have been keeping us posted!
eklemetti | March 26, 2010Alright, I'm actually in Wisconsin right now for a wedding, but this was too cool to pass up ... the folks from the NASA Earth Observatory sent me this image (Natural-color, 10m/pixel) from the Advanced Land Imager aboard EO-1 of the Eyjafjallajokull-Fimmvörduháls eruption, both taken on March 24, 2010.

You can clearly see the flow heading down the drainage to the east, slowly snaking down the snow covered area. I think the steam plume on far…

It has been hard to keep up with the flood of news from the Eyjafjallajokull eruption in Iceland. Eruptions readers have done a good job with getting new images, videos and info up as they happen, so you might want to peruse the comments for those sorts of tidbits (along with discussion of what might be happening).
Here is the latest:
The eruption at Fimmvörduháls (considering the eruption is actually occurring between the ice caps) could last weeks to months, which isn't too…
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 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.…

Piton de la Fournaise erupting on December 14, 2009. Image courtesy of the Observatoire Volcanologique du Piton de la Fournaise.
A while back I reported on a brief eruption at Piton de la Fournaise on Reunion Island and now a number of Eruptions readers have pointed out to me that it has erupted again (french). Seems like a similar event to the previous, with fissure vent effusive flows on the southern and eastern slopes of the shield volcano.
Here is the report from Guillaume Levieux of the Observatoire Volcanologique du Piton de la Fournaise:
Piton de la Fournaise volcano erupted Monday,…
