Galeras Volcano (Colombia)
1.22 N, 77.37 W, summit elevation 4276 m, complex volcano
Saturday 8th April 2006
Increased seismicity at Galeras volcano has led the Colombian Institute of Geology and Mining (INGEOMINAS) to increase the alert status to Level II. Aerial observations have confirmed the main crater is capped with solidified lava, and that gas and ash emissions are taking place in small quantity. Steam emissions are visible 500 m above the volcano. This type of activity has historically preceded volcanic eruptions. The National Director of INGEOMINAS has declared that the situation as "extremely critical". Several communities around the volcano are at high risk in Pasto, Nariño and La Florida. The Government has activated its National Operations Committee and reactivated the order to evacuate high-risk areas. Civil Defense has declared an Orange Alert for Pasto, a town of 5300 people. During the week of 20-27 March 710 earthquakes were registered at the volcano, compared to 527 this week.
