Eruptions

Idunn Mons on Venus with recent emissivity data from the Venus Express overlaid on the topography, suggesting recent lava flows. NASA released images today that suggest that the surface of Venus has experienced some relatively recent volcanic events (geologically speaking). By examining the surface in infrared, the Venus Express, launched by the European Space Agency…

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…

The 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…

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 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…

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,…

Cleaning up some news … busy week leading up to a field trip I am helping co-lead to Death Valley next week. Ubehebe Crater in Death Valley, California First off, I want to say how amazed I am at the great discussion that went on all weekend about the signs of potential activity in Iceland.…

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…

Some news for a busy Tuesday: The crater at Poas volcano in Costa Rica, taken February 25, 2010. Image courtesy of OVSICORI by Federico Chavarria. After the MSNBC debacle, it is nice to see some good articles on why the Chilean earthquake was overall less disastrous than the Haitian earthquake, why the tsunami wasn’t as…
