| Resumo: | A number of significant disasters associated to slope inestability occurred in the state of Puebla as a consequence of the extraordinary precipitations of October 1999. Specifically, the municipality of Teziutlán was severely affected by complex landslides characterized by sliding and flowing mechanisms. Several houses were buried, causing over 100 deaths, and considerable damage to the local infrastructure as a result of a single event A characterization of landslide génesis and dynamics in Teziutlán is presented in this paper. It includes the elaboration of a geomorphic map, where the mean morphogenetic units are identified to distinguish áreas with a high massmovement incidence. To this end, records of the events that took place in the Sierra Norte de Puebla in October 1999 were integrated, allowing to identify the most landslide-susceptible zones according of their morphology and materials' composition. The results indícate that around 90% of the October 99 landslides took place within the pyroclastic piedmont unit. |
