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…

A large explosion occurred this morning that was accompanied by falling ash and rocks (ballistic bombs) from the event. It is unclear how far the volcanic products travelled from the vent, but Colombian officials…

However, even with the eruption, apparently there are very few people in the evacuation centers – never a good sign if…
