Eruptions

Archives for October, 2009

There has been news over the last few days of a number of volcanoes in Colombia, so I thought I’d try to gather it up here: The steaming summit of Nevado del Huila in Colombia Nevado del Huila has been ramping up its ash emissions, potentially pointing towards new eruptions from the crater dome. The…

The first Q&A with Dr. Jonathan Castro was such a success, I’m going to try to make this a regular feature. On that note, Eruptions reader Dr. Boris Behncke has volunteered to be the second geologist to take the plunge. Here is a little about Boris and his work: I’ve studied geology first in Bochum,…

The SI/USGS GVP site is back up and running – and they’ve posted a new weekly volcano activity report. Enjoy! Highlights include: Nevado del Huila in Colombia has been showing signs that a new eruption might be starting. Seismicity has increased and minor ash fall has been reported, leading to an increase in the alert…

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 ……

GSA 2009 Wrap Up – Part 1

I did an excellent job of forgetting my notes from GSA 2009, so no wrap up on the meeting until tomorrow, but we do have some new volcano news to digest: The crater of El Reventador in Ecuador in an undated photo. Ecuadorian officials have called for evacuations around El Reventador. The Ecuadorian Geophysics Institute…

GSA 2009 pre-update

However, there was quite a bit of interesting info I heard which I’ll likely post tomorrow including:…
