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. [mehr]
