SERNAGEOMIN reported that clouds obscured camera views of Chaitén’s eruption plume during most of 26-29 August. Glimpses utilizing the web camera revealed that continuous ash plumes rose to an altitude of 1.5 km (4,900 ft) a.s.l. and drifted SW. They also reported that seismicity had increased slightly during the previous few days.
Based on web camera views and analysis of satellite imagery, the Buenos Aires VAAC reported that during 27-29 August ash plumes rose to altitudes of 1.8-3 km (6,000-10,000 ft) a.s.l. and drifted SE.
