Jocotitlán rises above the Toluca basin and is seen here from the NW. This side of the edifice has 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 km2 area to the NE.

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 partial collapse of the volcano. This catastrophic collapse was radiocarbon dated to about 9,690 years ago. The avalanche traveled a maximum distance of 12 km and covered an area of 80 km2. The 2.8 km3 avalanche deposit is overlain by pyroclastic surge and airfall pumice deposits that were erupted immediately following the collapse.

This conical hill is among many hummocks found at the NE base of Jocotitlán volcano and represents part of the edifice that collapsed in a massive volcanic debris avalanche about 9,700 years ago. The hummocks contain abundant large blocks (1-10 m in diameter) and larger mega-blocks (10-20 m in diameter). The largest 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. The 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 9,700 years ago. The debris avalanche deposit includes several conical hummocks (such as those to 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 km2.
