After the 3 powerful eruptive events on 12 July, seismic activity has decreased at Galeras volcano. The alert level was lowered to 2.

Galeras volcano had a strong explosive eruption on 12 July at 10h58 local time, producing an ash plume reaching 12 km altitude. The event was followed by two further explosions at 14h36 and 21h02 local time. 
Ash falls were reported in the localities of  La Florida, Ancuyá, Sandoná and Consacáes. Authorities started to evacuate about 10,000 people from the areas nearest to the volcano.
The eruption was preceded by a relatively calm period of lava dome growth interupted only by a weak explosion on 9 July accompanied by a minor swarm of earthquakes.
The events mark Galeras' typical trend of erupting and have been expected by scientists of the monitoring institute INGEOMINAS. A pdf report about the eruption can be downloaded from their website.

Seismic and thermal activity at Galeras has decreased, but the volcano remains on elevated alert.

Thu, 30 Mar 2006, 16:06

Galeras has been showing an increase in tremor since the morning of 28 March, as INGEOMINAS reports. The Alert Level was raised from 3 ("changes in the behavior of volcanic activity have been noted") to 2 ("likely eruption in days or weeks"). In addition to the tremor, seismic instruments detected very shallow low-energy hybrid signals, similar to ones recorded during 1991-1993 when dome emplacement occurred on the main crater's floor.

Increased seismicity continues at Galeras volcano, with an average of 200 small earthquakes occurring per day. In addition, slight deformation and an increase of sulphur dioxide emission (ca. 300 tons per day) are recorded at the volcano. Visible observation shows strong degassing at the active cone and around the lava dome. Galeras remained at Alert Level 3 ("changes in the behavior of volcanic activity have been noted").

Thu, 2 Feb 2006, 17:49

The lava dome in the main crater of Galeras volcano continues to grow. Strong degassing is occurring in several areas of the active cone and around the dome. Galeras remains at Alert Level 3 (the second highest).
