2009 is over! If you missed the Volcanic Year in Review, check out my summary of the volcanic events that captivated many of us over the past year. However, only one event will get the coveted 2009 Pliny for Volcanic Event of the Year. A lot of you wrote in with votes and comments –…

2009: The Volcanic Year in Review

Here 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. Waimangu Geothermal Valley in New…

We get a new update from the Smithsonian/USGS Global Volcanism Program … Highlights (not counting Soufriere Hills or Gaua) include: The Weekly Report mentions the mystery eruption/noneruption of Karkar in PNG. Specifically, they report: The report also stated that ash had merged with a thunderstorm cloud and had become unidentifiable. Two ash plumes (11/25, 26)…

I’ll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning. Undated image of Mayon in the Philippines. The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that

A few weeks ago I asked you to submit questions on the 2008-present Chaiten eruption in Chile to pose to Dr. Jonathan Castro. Dr. Castro recently had a paper on the ascent rates of Chaiten rhyolite published in Nature and he kindly volunteered to answer your questions. Here are the answers to selected questions ……

A pile of new volcano images

Sometimes it is hard to keep up with the mountain of remote sensing (or not so remote) images that get released on the internet. Over the last few days, the NASA Earth Observatory has released a bunch of images/videos of current eruptions, so I thought I’d round them all up here for you to peruse.…

Chaiten eruption still going strong

As fall descends on the northern hemisphere, spring starts in the southern. Luckily for us, it means that we get better views of the southern Andes in Chile … which means the NASA EO could train one of the many “eyes in the sky” (specifically the EO-1) on Chaiten. The volcano is still erupting, going…

The slow summer for volcanic eruptions continue. Only 11 updates in this week’s USGS/SI report. Thanks again to SI’s Sally Kuhn Sennert for compiling the news! Highlights this week include (not including Kilauea) include: Tungurahua in Ecuador produced some minor lahars on August 21 to go with steam-and-gas emissions. Popocatépetl in Mexico produced an ash…
