Between 1-15 December 2009 eruptions continued at Chaiten volcano in Chile. On 7th December emissions occurred on the north and south side of the lava dome. On that day there was a block and ash flow which indicates the dome continues to grow. There were a large number of small magnitude earthquakes. The seismicity decreased, [...]
The Mayor of Chaiten has said that some residents wish to return to the town which was destroyed by the eruptions in 2008-09. Residents are still displaced from the town 18 months after the eruption. There are many people still living in the surrounding area of Chaiten, and some assistance is being given to people [...]
A flyover of Chaiten volcano on 29th September 2009 showed the volcano continues to erupt. There has been a change in morphology which reflects changing conditions at the summit dome complex. A third dome is forming in the centre west of the crater. During the observation period of 16-30 September 2009 ash emissions reached a [...]

Seismicity has remained high at Chaiten volcano, Chile, during the period 16-22 July. The eruption continues unchanged with a column of ash and steam rising 1.5 km above the summit. Block and ash flows still persist, indicating the dome complex has continued to grow, particularly towards the western sector of the caldera. Some strong emissions [...]
Eruptive activity continues at Chaiten volcano in Chile. Over the past week there has been a decrease in earthquake number and magnitude, with 17 earthquakes recorded per day. Ash emissions rise 1.5 km above the summit. A lava dome continues to grow in the summit crater, which may collapse generating ash and block flows in [...]
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 [...]
Since 28th May there have been weak explosions at Llaima volcano in Chile. The main crater remains obstructed, and there is an opening of a fissure on the eastern flank of the volcano. Activity remains variable at Llaima volcano with the possibility of ash emissions, lava flows, and pyroclastic flows. The volcano remains at alert [...]
Dome growth continues in the summit crater at Chaiten volcano, Chile. The surface morphology of the dome is complex and uneven. The central pinnacle of the dome has broken into three main blocks. The tallest spine is 100 m high. Continuing rapid growth of the dome creates a collapse risk with the subsequent hazard of [...]
