Cay
About Cay
Volcán Cay, located E of Macá volcano and NW of the town of Puerto Aisén, is a basaltic to dacitic stratovolcano. An explosion crater is open to the E, and about a half dozen explosion craters and pyroclastic cones lie along a fissure trending SW of the summit. Another 10 basaltic pyroclastic cones are located along a second parallel fissure 5 km SE that is part of the major regional Liquiñe-Ofqui fault zone. These cones were considered to be Holocene by González-Ferrán (1995), but Naranjo and Stern (2004) found no evidence for Holocene tephra deposits.
