Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Chaiten
The dome-filled caldera of Chaitén volcano is seen in an aerial view from the south taken prior to an eruption in 2008. The volcano is located 10 km NE of the town of Chaitén on the Gulf of Corcovado. The elliptical 2.5 x 4 km wide summit caldera was formed during an eruption dated at about 9400 years ago. A rhyolitic, 962-m-high obsidian lava dome occupies much of the caldera floor. Photo by Eric Manríquez T. (Instituto Geográfico Militar).

Chaitén is a small caldera (~3 km in diameter) located 10 km NE of the town of Chaitén on the Gulf of Corcovado. Multiple explosive eruptions throughout the Holocene have been identified. A rhyolitic obsidian lava dome occupies much of the caldera floor. Obsidian cobbles from this dome found in the Blanco River are the source of artifacts from archaeological sites along the Pacific coast as far as 400 km from the volcano to the N and S. The caldera is breached on the SW side by a river that drains to the bay of Chaitén. The first recorded eruption, beginning in 2008, produced major rhyolitic explosive activity and building a new dome and tephra cone on the older rhyolite dome.
