Eruptions reader Boris Behncke pointed out that things are afoot in the Halema`uma`u Crater at Kilauea.

Somehow I haven’t posted a bunch of interesting items collected over the last few weeks, so I need to catch up. A pre-emptive hat tip to everyone who has sent me links or notes that might seem familiar in this post. Tungurahua in Ecuador erupting in 2000. First off, those of you looking for information…

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…

Looks like last night was busy, volcanically speaking. Eruptions readers noted that VAAC warning of ash from both Mayon (to 10,000 feet / 3.0 km) and Bezymianny (to 32,000 feet / 10 km) were issued {hat tip to Chance Metz for the updates}. Here is some more news on these ongoing events: Mayon erupting in…

It’s the last week of classes and it’s also AGU (which I will be missing for the first time in 5 years). If you happen to be at the big meeting in SF and hear something you think we’d like to hear, feel free to drop me a line or leave a comment so we…

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…

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 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…
