Eruptions at Chaitén volcano in Chile have decreased, but still remain continuous. Last Sunday the column of gas and ash reached about 3.5 km above sea level, with occasional eruptions reaching 5 km high. A lava dome continues to grow in the crater and exceeds the old dome in height. South of the dome a 200 m wide crater has formed, which continuously erupts ash and gases. Ash continues to fill rivers surrounding the volcano. Lahars are still entering Chaitén town. Seismic signals from explosions, gas emission, and pyroclastic flows have decreased in intensity and frequency. Future hazards at the volcano include dome collapse with pyroclastic flows, blockage of the vent followed by larger eruptions, and lateral eruptions.
