Volcano Hazards Program
eklemetti | December 31, 2009Here it is, my attempt to recap a year's worth of volcanic events. By no means is this supposed to capture every event, but rather the highlight/lowlights and what most captivated me during 2009. I'll be announcing the winner of the 2009 Pliny for Volcanic Event of the Year tomorrow.

January
The year started out with a trip to New Zealand (well, for me at least) and vistas of the Waimangu Valley, formed in the 1886 eruption of Tarawera on the North Island. We were also still thinking about the late 2008…

Thanks to all the readers who have been avidly discussing a number of fascinating topics over the weekend.
I have seen/read a little bit about the tectonic-forcing mechanism idea for some caldera-style eruptions. The biggest thing to keep in mind is that the caldera-forming event - that is to say the collapse of the roof into the chamber - isn't usually the "trigger" as much as a result of a large…

It has been busy busy week for me, capped off today with a talk about my field work in New Zealand (see above), so I don't have much to say. Not much new news today about the Saudi Arabian earthquake swarms, but again, I'll keep my eyes pealed (incidentally, I still haven't been able to figure out why no western news sources have even mentioned the swarm).
Anyway, here's are some volcanic tidbits to enjoy over the long weekend:

Last night I had the opportunity to see a talk given by YVO Scientist-in-Charge Dr. Jake Lowenstern as part of the Volcanological Society of Sacramento meeting and he gave a great talk on the state of volcano monitoring today in the U.S. He laid out a lot of details concerning the Volcano Hazards Program of the USGS and I thought I'd share some of them so we can all have an idea of the ups and downs of the VHP these days.
First off, nothing says fun like the U.S. Volcano Status Map! Apparently the dreaded watch "eye" was not meant to be a…
