Renewed activity has occurred at Chaiten Volcano in Chile. Report from police in Chaiten town indicated that at 3pm on 29th October 2008 explosions were heard at the volcano, and were accompanied by an ash column 2 km above the crater. Seismometers continue to measure earthquakes at the volcano. Lava extrusion continues to build the dome in the summit crater. Dome building has increased since 20th September. Continued growth of the lava dome creates an explosion hazard, which can produce ash emissions, rockfalls, or pyroclastic flows.
