Submarine eruption near Japan

The plume from submarine volcano Fukutoku-Okanoba, erupting in February 2010. Almost a year after the Hunga Tonga Hunga Ha’apai eruption, where an undersea volcano sprang forth from the deep – quite spectacularly, we have new footage of another undersea eruption. Fukutoku-Okanoba, off the coast of Minami Iwo, started to erupt yesterday (or, at least, erupt…

With all the talk of the current Yellowstone earthquake swarm, I thought it would worth it to write a post on the the structure and caldera – and why we get earthquake swarms that are structurally rather than magmatically-related. First off, lets think about why calderas formed. This is relatively simple – at least superficially.…

Steaming, gurgling mudpots in the active hydrothermal system of Yellowstone. For those of you following Yellowstone (I think there might be a few of you), I’ve plotted up the earthquakes since 1/27 (see below) – and sure enough, although there is a lot of scatter, they are getting shallower – however what this exactly means…

Tungurahua erupting in an undated AP photo (although I think it is the current 2010 activity.) It hasn’t really made it to much of the English-speaking news, but the current eruptive activity at Tungurahua appears to be on the up-tick. Hugo Yepes of the Geophysical Institute of Ecuador suggests that a larger eruption is not…

First off, I wanted to thank all of the Eruptions readers for making January the most popular month ever on this blog. I suppose I should give an assist to Yellowstone, but really, thanks for coming to the blog, reading the posts and engaging in all the great discussions that go on within its (cyber)walls.…
