The NW rim of Diamante caldera in the center of the image rises above the caldera floor in the foreground. The caldera was formed during voluminous rhyolitic explosive eruptions about 450,000 years ago that produced ashflows that extended radially more than 100 km from the caldera, covering much of the Central Valley of Chile and extending into Argentina. The conical snow-capped peak on the center horizon beyond rugged intervening peaks of the Andes is San José volcano.

Maipo volcano, seen here from the west, partially fills the Pleistocene Diamante caldera. The floor of the large 15 x 20 km caldera, which formed about 0.45 million years ago during an eruption that produced a 450 cu km ignimbrite, is visible below Maipo. The 5264-m-high basaltic-andesite stratovolcano has a relatively simple structure, but has a flank rhyodacitic lava-dome complex and pyroclastic cones on its eastern flank. Lava flows from these cones extend into Laguna Diamante on the eastern side of the caldera.

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.
