Ceboruco

Ceboruco is a dacitic stratovolcano located in Nayarit, Mexico, northwest of the Trans-Mexican Volcanic Belt.

[2] The mountain features one large caldera, created during the Jala eruption, with a smaller crater nested inside that formed when the Dos Equis lava dome collapsed during the Coapales eruption around 1100 AD.

[2] Cooled lava flows preserved around the volcano keep a record of the recent eruptions.

During the 500 years after the Jala eruption, the volcano was at its most active, leaving record of six major lava flows: the Copales, El Cajón, Coapan I, Coapan II, El Norte, and Ceboruco flows, all before the Spanish arrived in 1521.

The volcano remained active until the next major eruption in 1870, however volcanism was, for the most part, constrained within the calderas.
