Seismicity associated with the eruption of Chaitén volcano in Chile has decreased over the past week. Viscous lava is still being erupted into the dome, but this is occurring at a reduced rate. Dome collapse is still a danger, with pyroclastic flows potentially traveling down flanks of the volcano and valleys. On 19th of January there was a collapse of spines of the dome, with block and ash moving down the eastern and southeastern flank. During an overflight on 21st January the prominent spines were no longer present on the lava dome. Several steep landslides were visible on the eastern side of the dome. Thermal imaging shows many hotspots on the dome. The volcano is still at alert level RED due to the ongoing eruptions.
