Volcán Ceboruco is the only historically active volcano in the NW part of the Mexican Volcanic Belt. It is located near the triple junction between the North American, Cocos and Pacific tectonic plates.
Ceboruco is a complex stratovolcano that rises 1100 m above the flat floor of the NW-SE trending Tepic graben. It is composed primarily of trachydacite to trachyandesite lava flows alternating with tephra deposits, reflecting a complex history of constructive (effusive) and destructive (explosive) phases. It contains about 15 basaltic and andesitic cinder cones and lava flows that erupted along a NW-SE-trending line.
Ceboruco has 2 concentric summit calderas, the outer of which is 4 km in diameter and formed during the major rhyodacitic Jala Pumice eruption about 1000 years ago, which was the largest explosive eruption in Mexico during the past 10,000 years.
The last eruption of Ceboruco took place during 1870-75. Explosive eruptions occurred from a vent on the upper west flank and were followed by the extrusion of a 1.1 cu km dacitic lava flow that covers a large area on the lower western flank.
