Nevado del Ruiz volcano news & activity updates

Nevado del Ruiz volcano: activity summary 24 to 30 September 2012

Wednesday Oct 03, 2012 10:05 AM | BY: T

Current seismogram from Nevado del Ruiz (OLL station, INGEOMINAS)
Current seismogram from Nevado del Ruiz (OLL station, INGEOMINAS)
The volcano continues to produce strong steaming and has occasional small explosions. Seismic activity has been at generally low to intermediate levels.
Nevado del Ruiz volcano continued to have seismic activity associated mainly with rock fracturing within the volcanic edifice, which was located north, northeast, south and southeast of Arenas crater, at depths ranging from 1 to 6 km.
The highest magnitude recorded during the last week was 1.0 (Local Magnitude ML), corresponding to an earthquake that occurred on September 27 at 04:53 (local time).
Also, there was low-energy seismic activity related to fluid dynamics in volcanic conduits, located both in the Arenas crater, and to the east and southeast of it. There were further signs associated with small explosions and / or gas and ash emissions.
There is significant steaming and sulfur dioxide (SO2) emission. The gas and steam column reached a maximum height of 1800 m, and mostly drifts towards N, NW and W.
