The steam and ash plume from the Eyjafjallajökull subglacial eruption that started early morning, April 14, 2010. Well, after the brief respite when there was speculation Eyjafjallajökull-Fimmvörduháls eruption might be over, we now know what was going on. After the original fissures ceased activity, the magma found a new route to the surface, this time…

The Eyjafjallajökull-Fimmvörduháls eruption at night on April 10, 2010. I mentioned this earlier in the Monday Musings column, but the Eyjafjallajökull-Fimmvörduháls eruption in Iceland that started last month seems to be at a nadir of activity since its inception. This is being interpreted by the Icelandic Met Office as a sign that the eruption itself…

Lots to do! Tourists flock to the Eyjafjallajökull-Fimmvörduháls in Iceland. The media does love the term “supervolcano”, and a number of Eruptions readers sent me a link to the article on the dreaded submarine “supervolcanoes”. I would delve into this article from Live Science, but it sadly again does a dreadful job with a lot…

A view of the steaming Mt. Etna, taken on April 8, 2010 by Dr. Boris Behncke. Eruptions reader and member at Italian National Institute of Geophysics and Volcanology in Catania, Dr. Boris Behncke, has been keeping many of us appraised on the goings-on at Mt. Etna. A series of earthquakes occurred on April 2-3 along…

Volcanoes from space!

Actually, no the volcanoes aren’t from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit: A recent image of Chaiten taken by EO-1.

Reawakening Redoubt?

News comes out of Alaska that a small earthquake swarm has begun under Redoubt. This is the second such swarm since the volcano’s 2009 activity ceased. Most of the seismicity appears to be near…

A shot from the Hekla webcam showing the glow from the eruption of Eyjafjallajökull that started March 20, 2010. Quick note, but for those of you who have been following the seismicity at Eyjafjallajökull in Iceland, there is news from Iceland that an eruption has started. I will post more details as I can find…

Leaving for Death Valley tomorrow – I’ll be sure to take some pictures of Ubehebe Crater and the volcano at the Mirage. This will likely be the last new post until about a week from now, but look for the Erta’Ale Volcano Profile, maybe a new Mystery Volcano Photo and I’ll leave a thread open…

Did I mention its a busy week? The lava lake at Erta’Ale in 2008. Image courtesy of Stromboli Online. Our Icelandic saga continues, with more earthquakes and more speculation/information on the parts of Eruptions readers. Keep up the discussion – I’ll be fascinated to see who turns out to get closest to what actually happens,…

Eyjafjallajökull, an ice-capped volcano in Iceland that last erupted in 1823. We talked a few weeks ago of signs that there were increasing signs that an eruption could occur on Iceland – increased seismicity on the Reykjanes Ridge suggested that magma might be on the move. Now, we have two pieces of evidence that we…
