Chilean scientist think that new eruptions from the volcano could occur any time. SERNAGEOMIN's latest bulletin informs that the seismicity under Copahue has shown a significant change since 31 December. A number of quakes both related to fracturing of rocks and fluid movements appeared at shallow depths of 4 km and have been becoming shallower. Also, a change in the plume towards becoming denser and grayer, i.e. more ash-rich, has been noted in recent days. For this reason, the alert level was raised back to orange. [details]

dimanche, déc. 30, 2012
Visual and seismic activity have decreased at Copahue and no more ash emissions or incandescence have been observed since 29 Dec. It is thought that the small eruption that had started on 22 Dec has ended. It has emplaced a small body of lava (a lava dome) inside the crater which is now cooling, but still visible as a thermal anomaly on MODIS satellite data. ... [details]
