Photo Gallery

Jocotitlán is an isolated composite dacitic volcano that rises 1300 m above the Toluca basin. It is seen here from the NW, facing a horseshoe-shaped escarpment that formed as a result of gravitational failure of the summit during the early Holocene. The conical hills of Cerro San Miguel (left) and Cerro la Cruz (center) are part of the resulting debris-avalanche deposit that covers an 80 sq km area NE of the volcano. The latest known eruption of Jocotitlán occurred about 700 years ago.

The tree-covered hills in the foreground of this view of Jocotitlán from the NE are the steep, lobate front of a massive debris-avalanche deposit produced by collapse of the volcano. This catastrophic collapse was radiocarbon dated at about 9690 years ago. The avalanche traveled a maximum distance of 12 km and covered an area of 80 sq km. The 2.8 cu km avalanche deposit is overlain by pyroclastic-surge and airfall-pumice deposits that were erupted immediately following collapse of the edifice.

This conical hill is among many found at the NE base of Jocotitlán volcano and represents part of the edifice that collapsed in a massive volcanic landslide about 9700 years ago. The conical hills contain abundant large blocks (1-10 m in diameter) and are apparently cored by larger megablocks (10-20 m in diameter). The largest hummocks are up to 200 m high and occur within 3-5 km of the volcano along with large parallel transverse ridges up to 2.7 km long. Hummock size and height decrease towards the margins of the deposit.

The tree-covered hills in the foreground and center of this view from the summit of Jocotitlán volcano were formed during a massive debris avalanche produced by collapse of the volcano about 9700 years ago. The debris-avalanche deposit includes several steep-sided conical hummocks (such as those at the lower left) and large transverse ridges up to 2.7 km long. The avalanche traveled a maximum distance of 12 km to the NE and covered an area of 80 sq km.
