Copahue volcano news & activity updates

Copahue volcano (Chile / Argentina border) - eruption likely phreatic according to press release

Сб, 22 дек 2012, 19:57
According to SERNAGEOMIN, the eruption is most likely a small phreatic event. This is a abbreviated translation of the latest press release:
- From 10:45 local time, the seismic signal recorded at stations installed around the volcano Copahue showed a rapid increase and was characterized by strong low frequency tremor.
- The tremor signal correlated with an increase in the gas column, which turned black as ashes were erupted. The plume reached a height of 1.5 km and drifted about 13 km to the SW.
- Given the nature of the suddenly rising seismic signal with no detected precursory seismic activity, the low height of the eruption column, which implies a low temperature, and the presence of an extensive hydrothermal system at the volcano, the still continuing eruption is a minor phreatic eruption. It is expected to primarily affect areas near the crater and ash fall confined to proximal surrounding areas.
However, it is possible that the current activity evolves into a major event.
