Landslide inventory, teziutlán municipality, puebla, méxico (1942–2015)

Abstract

This article describes the spatial distribution of landslides in Teziutlán, Puebla, Mexico, which has been historically affected by mass movement processes. The most significant disaster associated with landslides in October 1999. Rainfall-triggered landslides and floods caused more than 100 deaths in Teziutlán and economic losses of US$233 million in Sierra Norte de Puebla. A multi-temporal landslide inventory map (1:25,000) for the period 1942–2015 was constructed by means of field observation and the analysis and interpretation of aerial photographs and satellite images. The inventory map includes 662 landslides and covers 163 km2. The total landslide area is in the order of 0.71 km2. Taking into account the scarp, channel and depositional area, the mean surface of the landslides is 1075 m2. The largest documented area was 17,512 m2. The smallest landslide area mapped was 24 m2. Most movements can be considered as having been small.
