Conical Maipo volcano rises above the floor of Diamante caldera in this NASA International Space Station view (with north to the top). A series of flank vents on the eastern side of the volcano produced lava flows that give the western shoreline of Laguna Maipo and irregular outline; a lava flow in 1826 blocked drainages on the caldera floor, forming the lake. The 15 x 20 km Diamante caldera was formed during a major explosion eruption about 450,000 years ago.
