The east rim of the 1982 crater at El Chichón is seen here from the rim of the larger somma crater. Erosional gulleys dissect pyroclastic-flow and -surge deposits that swept radially away from the 1982 crater. The rim here rises about 50 m above the moat between the two craters. Prior to the 1982 eruption a lava dome rose several hundred meters above the crater floor.
