Susceptibility to mass movements in the Cajamarca region, northern Perú and landslide Rodeopampa on February 22, 2010. On February 22, 2010, an old slide on the slopes the hill Rodeopampa was reactivated, causing damming Sócota Valley, a tributary of the Marañón River affect agricultural land and some houses of Rodeopampa in the body and head of the slip and St. Luis de Lucma in the Run up and reservoir, both located in the provinces of Chota and Cutervo, Cajamarca region, northern Peru. He formed a reservoir of 1640 m long and 400 m wide with a shut height of 70 to 90 m, which remained for months before being opened up naturally by the river. As this slide, different gravitational processes occurred during the anomalous rainfall in 2008, 1998 and 1983 in the northern region, being affected major routes into the mountains and forests of the region Cajamarca. These areas previously evaluated in the study of geological risk in the region, particularly Rodeopampa sector were compared with the susceptibility map produced. These areas are located in areas of high and very high susceptibility to landslides, helped to validate the map and its usefulness for disaster prevention and development planning.
