View of an eruption column from Chaitén Volcano, Chile, photographed on May 26, 2008. The caldera is about 3 km (1.9 miles) in diameter from rim to rim. The knobby feature between the eruption column and the left rim is part of a lava dome that formed after the 7,400 BC eruption. U.S. Geological Survey photograph by J.N. Marso.
