Mayon Update for 12/28/2009

Lava flows from Mayon, taken December 23, 2009. Volcano news over the holidays this year is still focused on Mayon in the Philippines. We’re reaching almost a month since the volcano starting showing signs of a major eruption, but no “big one” yet. Lava flows, ash and block-and-ash flows are continuing to be issued from…

Mayon eruption update for 12/16/2009

Lava on Mayon, December 2009, with Legazpi City in the foreground. The mainstream media has picked up on the activity at Mayon – I’ve seen it splashed across CNN, FoxNews, ABC, BBC and others.

Busy week at the Italian volcanoes

Here is a quick summary based on information from Dr. Behncke and Sonia Calvari of IGVN. Etna erupting in 1989. Image by Dr.…

All the news to start the week: Galeras with a grey ash-and-steam plume behind Pasto, Colombia. Well, after my article on Friday about Colombian volcanoes, Galeras must have decided it was left out. The volcano has been placed back at alert level Orange/II (eruption in days to weeks). An increase in seismicity and sulfur dioxide…

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

Living around (and in?) volcanoes

There are a couple article out today concerning volcanoes and the economy, one on the plus side, one on the minus side. Volcano Buono in Italy near Naples.
