Maipo

カルデラ · Chile-Argentina · 5323m

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.

地質学的概要

Maipo, a conical stratovolcano that straddles the Chile-Argentina border SE of Santiago, partially fills the 16 x 20 km Pleistocene Diamante caldera, which formed about 450,000 years ago during an eruption that produced an about 350 km3 of rhyolitic ignimbrite. The Pleistocene cones of Volcán Don Casimiro and Cerro Listado were formed on the SW rim and SW flank of the caldera, respectively. The post-caldera Maipo rises about 1,900 m above the caldera floor, and has several cones on the E flank along a series of en échelon NE-trending fractures. Lava flows from one of these cones blocked drainages in 1826 inside the caldera, forming Lake Diamante on the eastern caldera floor.

Wikipedia の要約

英語版の要約

Maipo is a stratovolcano in the Andes, lying on the border between Argentina and Chile. It is located 90 km (56 mi) south of Tupungato and about 100 km (62 mi) southeast of Santiago. It has a symmetrical, conical volcanic shape, and is among the southernmost 5,000 metre peaks in the Andes.
