Volcán Cay, located east of Macá volcano and NW of the town of Puerto Aisén, is a basaltic to dacitic stratovolcano. An explosion crater is open to the east, 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 second parallel fissure 5 km to the SE that is part of the major regional Liquiñe-Ofqui fault zone. These cones were considered to be of Holocene age by González-Ferrán (1995), but Naranjo and Stern (2004) found no evidence for Holocene tephra deposits.
The Global Volcanism Program is not aware of any Holocene eruptions from Cay. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Cay page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Cay.

Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
