Nevado del Ruiz volcano (Colombia) activity update
Wednesday Dec 18, 2013 13:08 PM | DOOR: TVolcanic activity at the surface (degassing) and inside (earthquakes) has remained comparably low.
During the last week, volcano-tectonic type earthquakes associated with rock fracturing within the volcanic structure occurred mainly in areas north, northeast and west of the Arenas crater at shallow depths between 2.8-4 km. The maximum magnitude recorded was a 2.8 ML (Local Magnitude) event at 13:27 (local time) on 14 December.

An earthquake swarm affected the volcano on 7 Oct, including a volcanic-tectonic quake of magnitude 2.7 at 3.2 km depth northeast of the Arenas crater. This could indicate that new magma has been rising into the shallow volcano's conduit, which might (or not) lead to new eruptive activity. ... Lees alle

Since the last update, the volcano has been relatively calm with only internal unrest in the form of fluctuating seismic activity. Manizales observatory reports a slight increase during the past week, with earthquakes clustered in the usual location (presumably an area of magma storage) about 3.5 km NE of the Arenas crater at depths between 4-7 km. ...
