Tres Vírgenes

Tres Vírgenes is a volcanic complex in Baja California Sur on the Baja California Peninsula, where a ridge in the Gulf of California rift zone connects the peninsula to active offshore tectonics. It consists of three northeast-to-southwest aligned stratovolcanoes—El Viejo, El Azufre, and El Vírgen—whose ages show volcanic activity migrating southwestward over time. Forming from about 300,000 years ago to at least 22,000 years ago, the complex includes lava domes, scoria cones, pyroclastic fans, and andesitic to dacitic flows. Its uncertain most recent eruption and its preserved sequence of volcanism make it important for understanding the tectonic and magmatic evolution of the Gulf of California region.
