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…

There have been a number of articles floating around the popular press for the last week that I thought I would touch on briefly … always fun to decipher the real news from the hype. Active fumaroles on Datun Mountain in Taipei. An article out of the Taipei Times suggests that the city of Taipei…

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…

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…

Eruption at Gaua

A 1995 photo of Gaua volcano in Vanuatu. A few weeks ago I mentioned that there were signs that Mt. Garet, part of the larger Gaua volcano in Vanuatu was potentially showing signs of a eruption – the first since 1982. It turns out that the rumbling and sulfur odors reported by local residents were…

Happy Earth Science Week! Mt. Baker in Washington, USA. The Mount Baker Volcano Research Center (MBVCC) run out of Western Washington University has posted a series of new pictures and movies of the summit region of Mt. Baker (taken from 2006 to 2009). They also sent out links to some great images of the recently-exposed…

Rumblings at Gaua in Vanuatu

Gaua volcano in Vanuatu. Gaua volcano in Vanuatu is showing signs that it could be headed towards an eruption. News reports from the island nation in the south Pacific Ocean mention “increased seismic activity, generating sulphurous gas and ash into the atmosphere and affecting water supplies.” However, officials in Vanuatu have only raised Gaua’s alert…
