Eruptions

Archives for April, 2010

The Eyjafjallajökull-Fimmvörduháls eruption on April 7, 2010. Just as we were speculating that the Eyjafjallajökull-Fimmvörduháls eruption might be over, Icelandic officials may have ordered an evacuation for towns (icelandic) in the area (but information in english is scant). There have been a recent swarm of shallow earthquakes underneath the Eyjafjallajökull ice cap – and if…

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…

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…

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?

The steam plume from the new dome on Redoubt, taken in January 2010. Image courtesy of USGS/AVO, taken by Dennis Anderson. 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…

Quick 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…

Sunny and 80 here in Ohio today. That could mean only one thing that is likely on everyone’s mind. (I suppose there is also this other bit of news that we’ve been following, too.) The low, broad shield of Hawai`i’s Mauna Loa volcano. The USGS announced yesterday that inflation at Hawai`i’s Mauna Loa appears to…
