The Gígjökull outlet glacier on Eyjafjallajökull, showing the steaming lava flow carving its way through the glacier. Image taken May 5, 2010 by Dr. Joseph Licciardi. A quick update on the ongoing activity at Eyjafjallajökull: The activity at the volcano continues to be more explosive during the last few days than it was in the…

Grading grading grading! A webcam capture of the eruptive plume from Eyjafjallajökull on the morning of May 6, 2010. News: A quick update on the Eyjafjallajökull eruption: The volcano has been producing an impressive ash plume over the last day (see image above). The current ash plume is reaching 5.8-6 km height (19-20,000 ft) –…

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…

Volcano Profile: Erta Ale

The latest in my Volcano Profiles series, this one on Erta Ale in Ethiopia. The summit crater at Erta Ale in 1994 Location: The Afar region of Ethiopia.

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,…

Holiday snaps from space: Sakurajima

Eruptions reader Tim Stone sent me a link to the TwitPic feed for Soichi Noguchi, the Japanese astronaut currently on board of the International Space Station. The space traveller got a shot of Sakurajima from space, showing a beautiful…

This week’s USGS/Smithsonian GVP Volcano Update! Highlights include: A volcano I had never heard of in the Kuril islands is showing signs of life: Kharimkotan. Satellite images show a thermal anomaly at the summit of the volcano – its last known eruption was in 1933. Ash, sulfur dioxide and steam continue to erupt from Nyamuragira…

Somehow I haven’t posted a bunch of interesting items collected over the last few weeks, so I need to catch up. A pre-emptive hat tip to everyone who has sent me links or notes that might seem familiar in this post. Tungurahua in Ecuador erupting in 2000. First off, those of you looking for information…
