The NASA Earth Observatory has been dazzling us with images from the Eyjafjallajökull eruption for months – but they have been dazzling us with volcanoes images for years! Here are two more images for those of you who love seeing volcanoes from above: Cleveland, Alaska As I mentioned earlier this week, Cleveland volcano likely had…

For all of you going into withdrawal now that Eyjafjallajökull seems to have quieted down, there are two eruptions of note that aren’t in the North Atlantic: Undated image of the Barujari cone at Mt. Rinjani in Indonesia. Arenal in Costa Rica – which is almost always sputtering away – had a more significant explosive…

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) –…

Webcam capture of Eyjafjallajökull erupting on May 2, 2010. You can see the steam plume on the middle flanks of the volcano – this is likely a lava flow coming from the summit vents. A brief update on activity at Eyjafjallajökull: Overnight, the lava flows from Eyjafjallajökull could be seen in the crater of the…

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…

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. Image courtesy of the NASA Earth Observatory. There…

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…

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…

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…
