Finally, a chance to catch up a bit … ! Yasur erupting in May of 2010. Some news from the world of volcanoes: The BBC has a series of videos one the fallout from the Eyjafjallajökull eruption – including a look at the area around the volcano and how the economy has been affected by…

Mt. Hood in Oregon, taken August 2008. Image by Erik Klemetti. Click on the image to see a larger version. Quick news! I’m not going to go into too much depth right now about the recent study published in Nature Geoscience on Mt. Hood in Oregon – I plan to talk about it more in…

Climate, volcanism and the Andes

The northern Chilean and southern Peruvian Andes are full of volcanoes that look stunning – I mean, jaw-dropping details of volcanism litter the landscape. The reason for this is two fold: (1) there is an awful lot of volcanism in the northern Chilean/southern Peruvian Andes (as known as the Central Volcanic Zone) – and has…

Tourists hiking next to an active lava flow on Pacaya in Guatemala in 2006. I’m flying back to Ohio today after a successful few weeks of fieldwork/paper writing. Apparently I have a pile of tomatoes waiting in our garden in Granville … ! On to news: To go with the news that lava flows from…

This week went fast, didn’t it? The Baekdu caldera along the North Korean/Chinese border. The NASA Earth Observatory have been giving us a steady diet of volcanic plumes over the last week, including PNG’s Ulawun, Russia’s Sarychev Peak (a very faint plume), both an ASTER and Terra image of the summit region at Kliuchevskoi and…

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…

News, news, news! Ash from Eyjafjallajökull piling up on a roof at Seljavellir. Image courtesy of the IMO, by Ari Tryggvason. The latest from Eyjafjallajökull has the volcano continuing to puff away – producing intermittent airspace closures over Europe. The Icelandic Met Office reports a ~7 km (21,000 foot) ash plume, but they note that…

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…
