Mentolat

Stratovolcano · Chile · 1603m

Volcán Mentolat is an ice-filled 6-km-wide caldera in the central part of Magdalena Island, across the Puyuhuapi strait from the town of Puerto Cisnes. A young-looking andesitic lava flow on the west side of the volcano may be its most recent product. Historical reports describe an eruption at the beginning of the 18th century that could refer to this lava flow.

Geological summary

Volcán Mentolat is an ice-filled 6-km-wide caldera in the central part of Magdalena Island across the Puyuhuapi strait from Puerto Cisnes. An eruption about 7,000 years ago produced a pumice and scoria layer that extends to the SE. A young-looking andesitic lava flow on the SW flank may be its most recent product. Reports by Serrano describe an eruption at the beginning of the 18th century that could refer to this lava flow.
