Abstract

This investigation illustrates the landslides and geomorphologic changes of debris flow deposits in the town of Santa Cruz Pueblo Nuevo, State of Mexico, by using a multicriteria analysis in Geographic Information Systems to obtain a potential hazard map. Unstable areas are mainly along first-order tributary streams and meander bends developed on lahars, pyroclastic flows, and pumice fall deposits whose stability has decreased in the basin. On June 24, 1940, a large debris flow partially destroyed the town of Santa Cruz Pueblo Nuevo. Today, the town is settled in the alluvial fan of the old debris flows deposit. It is highly probable that the town will be affected again by landslides and debris flows. In an attempt to prevent future debris flows, walls of containment (gabions) have been constructed along the principal channel of the river La Ciénaga; nevertheless, in every rainy season the gabions are saturated and frequently destroyed
