Eruptive History

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

Deformation History

There is no Deformation History data available for Tequila.

Emission History

There is no Emissions History data available for Tequila.

The dramatic spine in the summit crater of Tequila volcano rises 300 m above the crater floor. The dacitic spine, similar to the one at Sangangüey volcano, has been dated at 210,000 years and occupies a summit depression that is breached to the NE. The spine appears to represent the latest activity from the central vent of Tequila.

Volcán Tequila is an eroded andesitic-dacitic volcano of Pleistocene age that rises about 1800 m above the surrounding plains. Tequila is the SE-most of a chain of calc-alkaline stratovolcanoes NW of Guadalajara. A prominent 300-m-high summit spine, similar to that at Sangangüey volcano, can be seen here in the center of the summit crater, which was been breached to the NE, in the direction of the photo. The volcano is surrounded by a series of older flank rhyolitic lava domes, obsidian flows, and basaltic cinder cones.

The summit depression of Tequila volcano is breached narrowly to the NE and originated from erosional excavation. A prominent 300-m-high dacitic spine, left after erosional removal of softer rocks surrounding the vent, forms the dramatic steep-sided peak at the left. The spine was dated at about 210,000 years and probably represents the latest activity from the central vent.

The south flank of the erosionally modified Tequila volcano is seen in an aerial view. The oldest lava flows from the Pleistocene stratovolcano overlie a south-flank rhyolitic lava dome dated at about 460,000 years. Summit crater activity ceased about 210,000 years ago, but flank eruptions producing andesitic lava flows and basaltic cinder cones continued until the late Pleistocene.
