SERNAGEOMIN reported that on 5 November the S bank of the Chaitén River (locally known as the Blanco) had overflowed and flooded local houses due to intense rains a few days before.
Based on observations of satellite imagery and web camera views, the Buenos Aires VAAC reported that during 9-11 November ash plumes from Chaitén rose to altitudes 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted ESE, E, and NE. A thermal anomaly was present on 10 November.
