Overview of Chaitén Volcano, Chile, and its 2008-2009 eruption

Chaitén Volcano erupted unexpectedly in May 2008 in one of the largest eruptions globally since the 1990s. It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of its aspects monitored. The eruption consisted o...

It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of its aspects monitored. The eruption consisted of an approximately 2-week-long explosive phase that generated as much as 1 km³ bulk volume tephra (~0.3 km³ dense rock equivalent) followed by an approximately 20-month-long effusive phase that erupted about 0.8 km³ of high-silica rhyolite lava that formed a new dome within the volcano's caldera.

This edition of Andean Geology contains a selection of papers that discuss new insights on the eruptive history of Chaitén Volcano, and the broad impacts of and new insights obtained from analyses of the 2008-2009 eruption.
