Volcán Cay is a probably still active stratovolcano in southern Chile, 15 km NE of Maca volcano and NW of the town of Puerto Aisén. Like Maca and Hudson volcanoes, Cay is one of the large composite central volcanoes in the South Andean Volcanic Zone.
Cay volcano is basaltic and dacitic in composition. It contains an explosion crater open to the east, and about a half dozen explosion craters and pyroclastic cones along a fissure trending SW of the summit.
Another 10 basaltic cinder cones are located along a second parallel fissure 5 km to the SE, which is part of the major regional Liquiñe-Ofqui fault zone.
