Nevado del Ruiz volcano news & activity updates

Nevado del Ruiz volcano (Colombia), activity update: increase in shallow earthquakes under Arenas crater

Sunday Feb 26, 2012 06:56 AM | BY: T

From 12:30 hours local time on February 23, a new increase in seismic activity of the Nevado del Ruiz volcano began, characterized by the occurrence of shallow earthquakes associated with fluid movements and fracturing of rock. INGEOMINAS also measured increased SO2 emissions and some changes in strain measurements.
So far, the energy level of this increase is low compared with previous episodes of unrest, but small eruptions in the near future are possible.
The seismicity is located under the active Arenas crater at depths ranging between 0.5 and 3 km, and reached a maximum recorded magnitude of 1.4 on the Richter scale.

The Nevado del Ruiz volcano (infamous for the tragic accident of the Armero mud flow disaster on 13 Nov 1985, killing more than 20,000 people) is becoming restless, as Erik Klemetti points out on his Eruptions Blog. Seismic activity beneath the volcano has increased dramatically during the past months, and it is likely that this is related to new magma rising within the volcano. [more]
