There are no Holocene eruptions known for Guazapa. 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.

Guazapa is a massive, eroded Pleistocene stratovolcano that rises 1000 m above the surrounding countryside NE of the capital city of San Salvador. The 1438-m-high basaltic volcano has no trace of its original summit crater, and deep canyons cut its flanks. Several young Holocene pyroclastic cones and lava flows of similar composition are found at the base of the volcano (Williams and Meyer-Abich, 1955). The Macanze scoria cone at the SE base of the volcano was considered to have probably been active only a few thousand years ago, however Weber and Wiesemann (1978) did not map Holocene vents in this area.
