Eruption at Gaua

A 1995 photo of Gaua volcano in Vanuatu. A few weeks ago I mentioned that there were signs that Mt. Garet, part of the larger Gaua volcano in Vanuatu was potentially showing signs of a eruption – the first since 1982. It turns out that the rumbling and sulfur odors reported by local residents were…

Before we get to the latest SI/USGS Weekly Volcanic Activity Report (WVAR), I wanted to draw your attention to some nifty NASA Earth Observatory images from the current activity at Soufriere Hills in Montserrat. After a few puffs last week, the volcano is now releasing a relatively constant stream of ash and steam, this after…

Happy Earth Science Week! Mt. Baker in Washington, USA. The Mount Baker Volcano Research Center (MBVCC) run out of Western Washington University has posted a series of new pictures and movies of the summit region of Mt. Baker (taken from 2006 to 2009).

I mentioned this at the end of the post on recent Nature paper by Castro and Dindwell on the speed of rhyolite magma ascent at Chaiten, but I’ll break it out to get your attention: >Do you have a burning question about the Chaiten magma you’d love to be able to ask Dr. Castro? He…

Chaiten has made it back into the news in the past couple days, both with new events at the caldera and with findings from the initial blast in May 2008. Here goes: Chaiten erupting in 2008. Third Dome Spotted The latest USGS/SI Weekly Volcanic Activity Report mentions that over the last week, Chaiten experienced what…

A pile of new volcano images

Sometimes it is hard to keep up with the mountain of remote sensing (or not so remote) images that get released on the internet. Over the last few days, the NASA Earth Observatory has released a bunch of images/videos of current eruptions, so I thought I’d round them all up here for you to peruse.…
