Melimoyu is an active stratovolcano in southern Chile, 40 km NW of the town of Puyuhuapi and 135 km south of Chaiten volcano.
The volcano has an 8 km wide ice-filled caldera, which is largely filled by a younger edifice and is drained by a glacier flowing through a gap in the NE caldera rim. The basaltic-andesite volcano is elongated 10 km in an E-W direction and has several cinder cones and a 1 km wide summit crater.
Two large explosive eruptions have been identified at Melimoyu volcano from tephra layers (MEL-1 and MEL-2) and been dated to ca. 1800 and 2800 years ago.
