Eruptive History

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

Photo Gallery

Guazapa is an eroded Pleistocene volcano NE of the capital city of San Salvador, and is seen here from the SW. There are several relatively young cones and lava flows of similar composition around the lower flanks.

Guazapa is seen here from the west, 3 km NE of the town of Guazapa. This eroded Pleistocene cone is one of the largest of the interior valley of El Salvador. Deep erosional valleys have formed down the flanks, and younger cones and lava flows are found around its base.

The massive Pleistocene Guazapa stratovolcano (left-center) is seen here in an aerial view from the SW with the Río Lempa behind it. The youngest flank vent of Guazapa is Cerro Macanze, which lies on the SE flank of the volcano, behind the two small volcanoes in the right-center part of the photo. The dark-colored unvegetated lava flow in the foreground was erupted in 1917 from the flank of San Salvador volcano.

The western side of Lake Ilopango is seen from the southern rim of Ilopango caldera. The broad peak on the right-hand horizon is the Pleistocene Guazapa volcano. The northern wall of Ilopango caldera rises about 400-500 m above the lake. Much of the caldera rim contains thick caldera-forming eruption deposits, and some lava domes are exposed in the caldera wall.

Volcán de Guazapa (near the center) rises beyond the Cerrón Grande reservoir (lower right) in this view from the NE. The smaller cone to the left of Guazapa is Cerro Tecomatepe. San Salvador volcano is to the upper left, the Santa Ana complex is the broad massif at the upper right, and peaks of the Sierra Apaneca near the Guatemalan border form the irregular ridge to the far right.
