description Cay fumaroles Overview
Cay fumaroles are gas vents associated with Cay, a stratovolcano in Chile's Southern Andes near Macá and northwest of Puerto Aisén. The Global Volcanism Program describes Cay as a basaltic to dacitic composite volcano with an east-facing explosion crater, several smaller explosion craters, and pyroclastic cones aligned along fissures, including one in the Liquiñe-Ofqui fault zone. No confirmed Holocene eruption is listed for Cay, so the fumaroles indicate a volcanic heat system without proving a documented recent eruption.
