The broad Cosigüina stratovolcano (also spelled Cosegüina), is seen here from the SE across the Gulf of Fonseca. Cosigüina is the NW-most of a chain of active volcanoes stretching across Nicaragua. The 872-m-high volcano is truncated by a 2 x 2.4 km wide caldera that is filled by a lake. In 1835 Cosigüina was the source of Nicaragua's largest historical eruption, which produced detonations heard as far away as Guatemala. Pyroclastic flows and surges reached the Gulf of Fonseca and produced ephemeral islands.
