Geological Summary

Conchagüita volcano occupies a small, 4-km-wide island in the Gulf of Fonseca across a narrow strait from Conchagua volcano. Late-stage eruptions formed a small, sharp-topped cone with a 100-m-wide summit crater at the southern end of the low 505-m-high island, and a youthful peninsula also extends from the island's eastern side. A crescent-shaped crater open to the west is located at the northern end of the island. Minor ash emissions in 1892 marked the only historical eruption from Conchagüita, the easternmost Holocene volcano in El Salvador.

The Global Volcanism Program is not aware of any Holocene eruptions from Conchaguita. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Conchaguita page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
