Nevado del Ruiz volcano - activity summary 29 Oct - 4 Nov
Wednesday Nov 07, 2012 08:31 AM | DOOR: T
Seismic recording on November 5 (OLL station)Earthquakes continued to reflect with rock fracturing within the volcanic edifice, mainly located north of Arenas crater and to a lesser extent in the northeast of the crater at depths ranged between 1.2 - 12 km. The maximum magnitude recorded during the last week was 0.8 ML (local magnitude) on 4 Nov at 05:10 (Local Time).
There was also low energy seismic activity related to fluid dynamics in volcanic conduits, located in the crater Arenas and east of it. Additionally there were signals associated with small explosions or gas and ash emissions.
INGEOMINAS continued to register significant flows of vapor and sulfur dioxide (SO2) into the atmosphere. The gas and steam column reached a maximum height of 2000 m above the volcano's summit.

In the last week the Nevado del Ruiz volcano continued to record seismic activity mainly associated with rock fracturing within the volcanic edifice, which was localized mainly to the north, northwest and east of Arenas crater at depths ranging between 1.5 and 10 km. The maximum magnitude recorded during the last week was 1.6 ML (local magnitude), corresponding to an earthquake that occurred on October 11 at 19:28 (local time). Was also recorded, low-energy seismic activity related to fluid dynamics in volcanic conduits, located in the crater Arenas and east of it. Additionally there were signals associated with small explosions or gas emissions and ash characteristics of the current state where the volcano is located. ... [meer...]
