Nevado del Ruiz volcano news & activity updates

Nevado del Ruiz volcano (Colombia) activity update: Activity Volcano Nevado del Ruiz from 8 to 14 October 2012

Wednesday Oct 17, 2012 10:05 AM | BY: T

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.
Continue to register significant flows of water vapor and sulfur dioxide (SO2) into the atmosphere, evidenced both in recording equipment installed in the volcano as satellite imagery. The gas and steam column reached a maximum height of 1630 m, and introduced preferential scattering direction north and west of the volcano, following the dominant wind regime in the area.
