Volcano Profile: Mt. Hood

Back in the days when Eruptions was on WordPress, I held a vote about what volcano should be the next to be profiled on this blog. The winner was Mt. Hood in Oregon, and after much waiting, the profile is here. I will actually be out of town until Monday doing some house shopping in…

Mt. Baker in Washington. Image taken by John Scurlock. Eruptions reader Robert Somerville brought to my attention the Mount Baker Volcano Research Center, a “clearinghouse for research on Mt. Baker” in Washington state. The center is a non-profit organization that is affiliated with the Geology Department at Western Washington University – and from the looks…

Mount Saint Helens in review

Image courtesy of USGS/CVO, taken March 8, 2005 from the Cascades Volcano Observatory, Vancouver, WA For those of you looking for something to relax with and read this weekend, you could wander over to the USGS website and download yourself a copy (for free and legally) of “A Volcano Rekindled: the Renewed Eruption of Mount…

Volcano monitoring in the news

So, there has been a lot of talk about “volcano monitoring” over the last 24 hours, now hasn’t there? Now, I’m not going to revisit this discussion, but as an example of why it might be important, there is an article today about the location of the Bataan Nuclear Power Plant in the Philippines (near…

More signs of melting at Redoubt

The “eruption watch” continues at Redoubt … Saturday revealed that things are getting hotter at the summit near the 1989/1990 dome (see picture above that made Redoubt famous in 1989). The overflight of the volcano revealed new holes in the summit glacial and a multitude of muddy streams formed from the meltwater. This area of…

The volcano-earthquake connection?

The BBC is reporting today on a study published in Earth and Planetary Science Letters that attempts to establish a connection between large earthquakes and subsequent volcanic eruptions. The study is focussed on large Chilean earthquakes over the last 200 years (Chile has had some of the biggest, hitting M9 on the Richter Scale) and…

All quiet on the Cascade front

The only volcanic arc in the lower 48 states continues to be pretty darn quiet according to the USGS. The Cascade range that spans from Lassen Peak in the south to Mt. Baker in the north (and maybe Mt. Garibaldi in Canada) has been remarkably quiet in terms of eruptions for the last century. In fact,…

Back from the field

I am back from my trek through the Oregon and California Cascades – including stops at Lassen Peak/Chaos Crags, Hood, Three Sisters and Crater Lake (an added bonus). I’ll try to catch up on the volcano news I’ve missed and post on anything exciting that happened soon, but otherwise I’ll be posting new news as…

Eruptions out of the office

I will be away from Eruptions for the next 2 weeks or so. I won’t be on vacation, I will actually be out on volcanoes themselves doing some much-needed fieldwork. It is a three volcano tour, starting with a trip to Lassen Peak to get a guided view with Michael Clynne of the USGS (the world…

I am beginning to feel like a broken record, but the latest reports from Chile indicate that the ongoing eruption at Chaiten is ramping back up again, almost 3 months after the initial eruption began. As usual, the nitty-gritty details are limited, but reports of increased ash emissions and seismic activity are heralding this increase…
