Melimoyu

成層火山 · Chile · 2400m

Glacier-clad Melimoyu volcano is seen from the NW from the town of Quellon on the island of Chiloe. The volcano lies across the Gulf of Corcovado beyond the small island cutting across the image in the foreground. Two prominent horns at the summit of the volcano rise above the rim of the summit crater. The large stratovolcano has an 8-km-wide, largely buried ice-filled caldera that is drained by a glacier through a notch in the NE caldera rim. Two late-Holocene tephra layers have been documented from Melimoyu.

地質学的概要

Melimoyu is a stratovolcano with an 8-km-wide, largely buried caldera located ~40 km NW of the town of Puyuhuapi. The ice-filled caldera is drained by a glacier through a notch in the NE caldera rim. The basaltic andesite volcano is elongated 10 km in an E-W direction and has several cinder cones. A 1-km-wide crater is located at its summit, and two late-Holocene tephra layers have been documented.
