There are no Holocene eruptions known for San Diego. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

An extensive volcanic field of fresh-looking basaltic cinder cones and barren lava flows near Lake Güija, which straddles the border between El Salvador and Guatemala, is named after its largest feature, 781-m-high Volcán de San Diego. A large basaltic lava flow from the San Diego cinder cone dammed the drainage and was responsible for the formation of Lake Güija. Volcanism is concentrated in two areas near Lake Güija--an area of volcanic cones including San Diego east of the lake, and an area of small cones north of the lake near the Guatemalan border, north of the Río Ostua. None of the eruptions in the San Diego volcanic field have been dated, but Williams and McBirney (1955) estimated that the latest eruption occurred within the past few thousand years. Quaternary volcanic rocks are also located across Lake Güija in Guatemala.
