Sunny and 80 here in Ohio today. That could mean only one thing that is likely on everyone’s mind. (I suppose there is also this other bit of news that we’ve been following, too.) The low, broad shield of Hawai`i’s Mauna Loa volcano. The USGS announced yesterday that inflation at Hawai`i’s Mauna Loa appears to…

I’m still playing catch-up after my week in the desert, so I’ve seen a lot of articles I’ve wanted to mention … but a certain other volcano has taken up a lot of my time. However, I will attempt to make amends for that now. By the way, would you believe Ubehebe Crater was closed?…

Mt. Baker in the northern Cascades of Washington. One of the best websites dedicated to any volcano is the Mt. Baker Volcano Research Center – hosted by Western Washington University. I’ve talked about it before, but David Tucker and his associates have put together an excellent resource on this (at least in my opinion) woefully…

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…

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.…

Some news for the last Friday in January: Volcanic lightning captured over Redoubt in March 2009. Tungurahua in Ecuador continues to erupt. Yesterday, the volcano spread ash over much of central Ecuador. Apparently people in Ecuador aren’t taking the hazard of ash too seriously, with many ignoring recommendations to wear masks when the ash is…
