Chaitén is a volcanic caldera in diameter, 17km west of the elongated, ice-capped Michinmahuida volcano, and northeast of Chaitén town in the Gulf of Corcovado, in southern Chile. The most recent eruptive phase of the volcano began on May 2 2008, and is ongoing. According to the Global Volcanism Program, radiocarbon dating of the last lava flow from the volcano suggests that its last previous eruption was in 7420 BC plus or minus 75 years. The translucent grey obsidian which had erupted from the volcano was used by pre-Columbian cultures as a raw material for artifacts.

| - Chaitén is a volcanic caldera in diameter, 17km west of the elongated, ice-capped Michinmahuida volcano, and northeast of Chaitén town in the Gulf of Corcovado, in southern Chile. The most recent eruptive phase of the volcano began on May 2 2008, and is ongoing. According to the Global Volcanism Program, radiocarbon dating of the last lava flow from the volcano suggests that its last previous eruption was in 7420 BC plus or minus 75 years. The caldera rim reaches 1,122m above sea level. Prior to the current eruption, it was mostly filled by a rhyolite obsidian lava dome that reached a height of , partly devoid of vegetation. Two small lakes occupied the caldera floor on the west and north sides of the lava dome. The translucent grey obsidian which had erupted from the volcano was used by pre-Columbian cultures as a raw material for artifacts.
