Here is Part 2 of the Q&A with Dr. Boris Behncke. You can also check out Part 1. Undated image of Stromboli in eruption. (Shirakawa Akira) 1. Would a large scale eruption (VEI 5 or greater) of Mt. Etna like the ones occurred in 122 BC and 1500 BC (disputed) be possible again in the…

First off, I want to thank Dr. Behncke for taking the time to answer your questions – and also, thank you to all who sent him some thought-provoking questions. In fact, the questions and answers take up about 12 pages of text, so the Q&A will be divided into two parts. If you want to…

We’ve arrived at Friday. The local time is 8:45 A.M. Set your watches accordingly. Batur, Indonesia Some news!

The rifting of Africa

Lava flows from the 2005 Mando Hararo eruption in Ethiopia. Alright, I had been attempting to ignore this story because it was, well, a little uninteresting at first, but it apparently has legs so I will tackle it. Slashdot has a post proclaiming: ‘Volcanic activity may split the African continent in two, creating a new…

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

GSA 2009 Wrap Up – Part 1

I finally remembered to bring my GSA notes with me to the office, so I can finally post a wrap up of what I saw/heard at the big 2009 meeting in Portland. I’ll have a specific post on Kasatochi – too much to say here. However, a great time was had by all! The crater…
