Eruptive History

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

Cerro Quemado scoria cone near of the outlet of Lake Güija has been extensively quarried, and only a remnant remains. The San Diego volcanic field is along the El Salvador/Guatemala border and contains numerous scoria cones and associated lava flows on both sides of Lake Güija.

An extensive volcanic field of scoria cones and lava flows near Lake Güija is named after its largest feature, Volcán de San Diego (upper right). A large lava flow from the San Diego scoria cone dammed the drainage and was responsible for the formation of 12-km-long Lake Güija, which lies mostly in El Salvador and extends across the border into Guatemala. Cerro el Tule scoria cone in the center of the photo is near the eastern shore of the lake.

Volcán de San Diego (upper right) is seen here from the south at the outlet of Lake Güija. The lake formed after lava flows from San Diego blocked the channel of the Desagüe river. Cerro el Tule (left) lies across a narrow channel from the lower flanks of San Diego. Cerro el Tule contains a summit crater and is one of the many cones of the San Diego volcanic field.

A panoramic view from the NE shows from left to right Volcán de San Diego, Cerro Masatepeque, and Loma Iguana. Laguna de Metapán is to the right. San Diego is the largest cone of a volcanic field surrounding Lake Güija on the El Salvador/Guatemala border. Lava flows from smaller vents of the San Diego volcanic field were responsible for blocking drainages and forming Laguna de Metapán, and the larger Lago de Güija was formed as a result of flows from Volcán de San Diego.

Young lava flows from Volcán de San Diego (left center) extend into Lake Güija (lower left). The prominent cinder cone on the lake shore directly south of Volcán de San Diego is Cerro el Tule. Young basaltic lava flows from other vents of the San Diego volcanic field in western El Salvador, such as Cerro la Vega de la Cana and Loma Iguana (upper left), extend into both Lake Güija and Laguna de Metapán at the top of the photo. The cinder cone north of Volcán de San Diego (surrounded by older lava flows) is Cerro Masatepeque.
