Chaitén Volcano, Chile - John Seach

Between 27th May and 2nd June there was steady growth in the lava dome at Chaiten volcano in Chile. Block and ash flow continued inside the crater, and was sometimes visible from Chaiten town. The eruption of Chaiten volcano remained unchanged, with a column of gas and ash rising up to 1.5 km above the dome complex. The persistence of block and ash flow indicates that dome growth continues, especially toward the western caldera, which is almost completely filled with viscous lava. There is a continued danger of dome collapse and pyroclastic flows which may affect adjacent valleys. Seismic activity remains high. Chaiten volcano remains on alert level RED.
