Galeras Erupts Again


2009 has been a busy year for Volcan Galeras in Colombia. The volcano has erupted at least twice this year already vigorously enough to prompt evacuations of the area. Galeras does tend to see cycles of eruptive activity, the last one started in 2000 after seven years of quiet. Many times, the eruptions are more visually impressive than hazardous (see the picture above from January 2008 from INGEOMINAS).

Luckily, Galeras is also once of the most watched volcanoes in South America. The INGEOMINAS (Colombian Geological Survey) staffs the Pasto Volcano Observatory (OVSP) to monitor the volcano as Pasto - population ~450,000 - sits in its shadow. The current eruption prompted the evacuation of 3,000 people living on the slopes of Galeras. The article only mentions minor ash fall but no injuries or damage.

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…
Sally Sennert from the Smithsonian Institution sent me an email to say that this week's USGS/Smithsonian Institute Weekly Volcanic Report will be delayed due to the inclement weather in the Washington DC area. She can't connect with the server, so the report can't be updated on the Smithsonian…
Today was a doubleheader for volcanic eruptions in the news: Today's explosive eruption from Mt. Etna. Image courtesy of the INGV. As I briefly mentioned earlier, Galeras in Colombia had an "atypical" eruption - apparently meaning it was non-explosive - that has prompted evacuations and a change…
