Small ash emission observed from the Pasto Volcano Observatory on 17 December 2012 (INGEOMINAS)
Two moderate earthquakes occurred near Galeras, Colombia's most active volcano, at a depth of ca 30 km. According to the Colombian Geological Service, the first quake occurred at 4:35 a.m. local time (about 0935 GMT) and registered 4.5 on the Richter scale. A minute later, a second quake measuring magnitude-4.3 hit, several mild aftershocks have followed. Two people died when their house was crushed by falling rocks and officials suspended classes in local schools as a precaution. The earthquakes have placed local authorities in the nearby city of Pasto, capital of Narino Province, on high alert as they fear that the currently dormant volcano might enter a new eruptive phase. ... alles lesen

Beschreibung:

Galeras is one of Colombia's most frequently active volcanoes. The dominantly andesitic volcano has been active for more than 1 million years, and two major caldera collapse eruptions took place during the past 100,000 years. Several collapse events have produced debris avalanches that swept to the west and left a large horseshoe-shaped caldera inside which the modern cone has been constructed.
Major explosive eruptions in the past thousands of years have produced widespread tephra deposits and pyroclastic flows that swept all but the southern flanks. A central cone slightly lower than the caldera rim has been the site of numerous small-to-moderate historical eruptions since the time of the Spanish conquistadors.

The fatal eruption in 1993
Galeras became active again in 1988 after 10 years of dormancy. It became infamous when it erupted on 14 January 1993, killing six volcanologists and three tourists who were inside the crater when it exploded. The group was part of an scientific conference excursion and their final decision to enter the crater, pushed forth by team leader Stanley Williams (who miracoulously survived), was and still is highly debated: the fatal decision was made despite the observation of a significantly increased number of particular earthquakes (tornillos), which had preceded previous eruptions and also started to occur in the days before the eruption.
