Copahue volcano (Chile): seismic activity decreases, alert lowered to orange

Tuesday Jun 04, 2013 06:32 AM | BY: T

The alert level of the volcano was lowered from "red" to "orange" in response to a declining trend of seismic activity recorded under the volcano. However, seismic activity remains significant and monitoring efforts continue at maximum level.
The Civil Defence (ONEMI) allowed the 621 evacuees from the Chilean side to return to their homes, while another about 600 evacuees from the Argentina side still remain in evacuation centers.

The seismic crisis continues, but has decreased in intensity. An eruption in the near future still remains a likely scenario, SERNAGEOMIN scientists emphazise, as this decrease in energy could be temporary. It is impossible to predict whether this is a question of days or weeks, or even if an eruption actually will occur. ... [more]

The earthquake swarm has increased and continues today, but the volcano has not yet erupted. The earthquakes are occurring at very high frequency (130 per hour) and are mostly "hybrid", i.e. related to both rock-fracturing and fluid-movements within the volcanic edifice. ... [more]

An eruption of the volcano could be imminent. SERNAGEOMIN and Civil Protection have raised the alert level to "red", based on the increasing earthquake activity under the volcano. Although so far no volcanic tremor (often a sign of eruptive activity) nor ash plumes have been detected via satellite, citizens of Caviahue in Argentina across the border from Copahue have reported explosions and incandescence from the volcano. ...

Although degassing and ash emissions have decreased, seismic activity at the volcano has picked up, SERNAGEOMIN reported. An average of 356 earthquakes per hour, sometimes merging into what looks as volcanic tremor, has been recorded recently. This could be related to intruding magma from a new batch of magma rising at the moment and as a result, phreatomagmatic or magmatic activity could occur at the surface in the near future. ... [more]

A steam and ash plume is rising about 1-1.5 km from the crater where it is emitted by 3 vents. Two of these emit only gas and steam. The third one erupts some ash as well, Chilean scientists found out during an helicopter overflight. ... [more]
