The Chaitén is an about 3 km wide volcanic caldera. It is situated about 10 kilometres in the northeast of the city Chaitén, near the Gulf of Corcovado on the western flank of the Michinmahuida volcano.
Before the May 2008 eruption began, the caldera contained a lava dome and several small lakes.
The Chaitén Volcano erupted on May 2, 2008 and was producing a plume of volcanic ash and steam that rose nearly 17 kilometers high and was visible on satellite images for hundreds of kilometers over the Atlantic Ocean. More than 4'000 people were evacuated from the town of Chaitén and some other villages.
