Eruptions

Archives for March, 2010

Superfast 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…

Coulées!

As a volcanologist, I am partial to impressive lava flows, especially in volcanoes that erupt material that you’d think wouldn’t produce big flows. For example, there are quite a few volcanoes in the Chilean Andes that erupt dacite lavas, which are relatively viscous (sticky), so you might expect it to erupt explosively. However, you can…

Map showing the location of submarine volcano Marsili, near the Italian coast. Image from INGV. The subject of submarine volcanism near Italy has come up before here on Eruptions but now it has made the jump into the worldwide media after some claims made by Enzo Boschi, president of the National Institute of Geophysics and…

Busy busy today, so just a brief update on the ongoing Fimmvörðuháls/Eyjafjallajokull eruption in Iceland. The coalesced vent of the Fimmvörðuháls fissure eruption in late March 2010. The eruption is still going, albeit potentially with a little less vigor than before – and you can watch it on the Vodafone webcam, along with these other…

Icelandic eruption from space

Alright, 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. The Fimmvörduháls eruption in Iceland, taken…

Alan Boyle, Science Editor for MSNBC.com, was kind enough to answer questions about science in the mainstream media after the fallout of the coverage of the Chilean earthquake. Alan Boyle, science editor for MSNBC.com Alan has been with MSNBC.com since 1996, covering science and technology. He has his own blog on space called the Cosmic…

I’m still playing catch-up after my week in the desert, so I’ve seen a lot of articles I’ve wanted to mention … but a certain other volcano has taken up a lot of my time. However, I will attempt to make amends for that now. By the way, would you believe Ubehebe Crater was closed?…

The fissure vent eruption near Eyjafjallajokull in Iceland. Image by Þorsteinn Gunnarsson, March 22, 2010. 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…

The steam-and-ash plume from Eyjafjallajokull in Iceland, March 22, 2010. Overnight, the Eyjafjallajokull eruption in Iceland added to its oeuvre, producing what is being reported to be a 8-km plume. Images of the plume (above) suggest (to me) that it is very water-rich, so likely this is the expanding(?) fissure interacting with snow, ice or…

The fissure vent eruption on Eyjafjallajokull in Iceland on March 21, 2010. The big news this morning is the eruption that started last night at Eyjafjallajokull in Iceland, producing a 1-km fissure vent. The pictures and videos I’ve seen so far have been quite impressive, with the classic look of a “curtain of fire”, where…
