UPDATE 2/15/2009 20:30 PM: Marta Calvache of INGEOMINAS says that seismicity has all but stopped at Galeras after the eruption Saturday night, however the area will be kept on alert for more potential activity. However, even with the eruption, apparently there are very few people in the evacuation centers – never a good sign if something really big were to happen at the restless Colombian volcano.
Last night, Galeras, near Pasto in Colombia, erupted, prompting an evacuation of nearly 7,000 people living near the volcano. The first CNN article linked above, for some reason, says that Galeras is not in a “heavily populated” area, however over 500,000 people live in or around Pasto, which is quite close to the volcano itself (see the CCTV video footage or the picture above for evidence). The current eruption has blanketed Pasto in “abundant ash” (according to the mayor of Pasto), where there have no been reported injuries or death, however, they did have to close down two water treatment plants. Beyond this, not too much is known about this eruption as it is cloudy and rainy near the volcano. That being said, with this much ash being deposited, there is likely a plinian component to the eruption, making it likely to have been a larger eruption than many of the recent events at Galeras, the last ending in January 2008 (VEI ~2).
