Sorry about the lack of posts – I’ve been not only frantically prepping for class and my Eyja talk, but also I’m somewhat under the weather with an ill-timed sickness, so even though there is stuff to talk about, I haven’t really had time/wherewithal to deal with it. However, expect big things from Eruptions next…

I am back from our trip into the Mountain West – and it was great (see some of the pictures below). We hit Yellowstone, the Grand Tetons, the Tobacco Root Mountains, Glacier and Craters of the Moon – and the weather held out on us just fine. This week is the last week before classes…

Kilauea lavas on the move near Kalapana. Image taken July 17, courtesy of the Hawaiian Volcano Observatory. Some news over the last few days: The lava flows from Kilauea are moving with a vengeance right now, damaging roads and heading for some structures. The lava flows near Kalapana have moved almost 200 meters since Sunday,…

News! Toba caldera in Indonesia. We’re all still talking about the Chilean earthquake and the coverage of the event. If you happen to live in the Columbus area, you might have heard me on WTVN talking about the earthquake as well. The Toba (Indonesia) eruption 74,000 years ago has been used by some researchers to…

The Great Earthquake Swarm at Yellowstone that ushered in 2010 seems to be dying down, at least according to the USGS earthquake reports and analysis of the seismicity by the University of Utah and YVO. The daily updates on the earthquake swarms by Utah has ended. Looking at the earthquake over the last 7 days…

News! Pakistan is home to the world’s tallest mud volcano in the region of Balochistan – and its somewhat near the reports of an “eruption” earlier this week. Guess what? Since Wednesday evening, seismicity at Yellowstone has dropped precipitously. The last batch of earthquakes on February 3rd were also back to deeper levels – 8-9…

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…

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.…

There has been a … ahem … healthy discussion of Yellowstone’s current earthquake swarm on Eruptions as of late. We’ve now reached ~1,500 measurable earthquakes over the last 11 days. The latest reports of the continuation of the swarm isn’t going to make anyone happy, but still, there are no signs that (a) this is…
