Lots of little pieces of news I’ve run across … time to play a little catch up. Stromboli: A volcano after Don Ho’s heart. Every once in a while, my RSS feeds will dredge up some articles from years gone by … and this week there were two New York Times pieces that are a…

Eruptions Word of the Day: Tuya

The latest Eruptions Word of the Day is “Tuya“. So, what is a tuya? This is a tuya: A tuya! Click on the image to see a larger version. Image by Erik Klemetti. Alright, well, that doesn’t entirely help, does it? Lets look at the feature the arrow indicates. Some observations: (1) It is low…

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. 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) –…

A shot of the strombolian activity at the vent of Eyjafjallajökull, taken on May 4, 2010. Image courtesy of the Iceland Met Office. 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 steam and ash plume from the Eyjafjallajökull subglacial eruption that started early morning, April 14, 2010. Well, after the brief respite when there was speculation Eyjafjallajökull-Fimmvörduháls eruption might be over, we now know what was going on. After the original fissures ceased activity, the magma found a new route to the surface, this time…

Eyjafjallajökull, an ice-capped volcano in Iceland that last erupted in 1823. We talked a few weeks ago of signs that there were increasing signs that an eruption could occur on Iceland – increased seismicity on the Reykjanes Ridge suggested that magma might be on the move. Now, we have two pieces of evidence that we…

Catching up with some news: Anatahan erupting in the northern Mariana Islands in 2003. I ran across this article right before I got sick, but its been popping up around the interwebs (and is pretty interesting). It details a study in Molecular Ecology that suggests that populations of caribou in Canada’s Yukon Territory were strongly…
