This week has been destroyed by workshops and my last death throes with a paper I am submitting on my research in New Zealand. And to think, I thought it might settle down a little after the students left. To news! Ash fall on a taxi cab near Guatemala’s Pacaya. Pacaya in Guatemala erupted yesterday…

The latest report from AVO on the volcano says a thermal…

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…

Time to play a little catch up … Eyjafjallajökull erupting in early May. Image by and courtesy of Martin Rietze. A brief update on our friend Eyjafjallajökull – the eruption plume from the volcano was considerably taller yesterday, reaching 6-9 km (20,000-30,000 feet), but prevailing winds meant the ash hazard was confined to areas in…

An aerial view of Eyjafjallajökull erupting on May 11, 2010, with the extent of the black ash from the eruption on Gígjökull clearly evident, along with the cracks in the glacier near the lava flow. Photo from the Icelandic Met Office, by Sigurlaug Hjaltadóttir. Since this past weekend’s disruptions due to Eyjafjallajökull, the air over…

Grading grading grading! A webcam capture of the eruptive plume from Eyjafjallajökull on the morning of May 6, 2010.

The latest news from the Eyjafjallajökull eruption has the volcano erupting more explosively again (see above), possibly due to an increased influx of water into the vent area – in any case,…

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…

The ash-and-steam plume from Eyjafjallajökull on April 19, 2010. Eyjafjallajökull in Iceland is slowly settling into a pattern of strombolian-to-surtseyan (depending on meltwater access to the crater) explosions that have been sending ash up to 2-5 km above the summit. We can see this new, more diffuse plume in the recent NASA EO image of…
