Cerro Macá

Maca

Stratovolcano · Chile · 2960m

Snow-mantled Volcán Maca, the highest volcano between Lanín and Lautaro, rises to 2960 m NW of Puerto Aisén. This glacier-covered, basaltic-to-andesitic stratovolcano lies within a caldera and contains a summit lava dome. Five flank cinder cones and lava domes lie along a NE-trending fissure that extends 15 km from the summit. The volcano lies along the regional Liquiñe-Ofqui fault zone. Volcan Cay (far right) lies to the NE of Maca.

Geological summary

The glacier-covered, basaltic-to-dacitic Volcán Macá stratovolcano lies within a caldera and contains a summit lava dome. Five flank cinder cones and lava domes lie along a NE-trending fissure that extends 15 km from the summit SW to Bahía Pérez. The volcano lies along the regional Liquiñe-Ofqui fault zone, and a lava flow from a cinder cone at Bahía Pérez erupted as recently as between 1450 and 1670 CE.
