Inventario debris-rockslides. Precordillera of San Juan, Argentina

Abstract

A total of 35 dry debris-rockslides were identified, which covered an area of 6.36 km2, accounting for 2.21% of the study area. The minimum, mean and the maximum slide areas are 0.001, 0.18, and 0.66 km2 respectively. Mean width of the rupture zone (Wr) is 301.30 m, and the mean length of the displaced mass (Ld) 373.22 m. The widths of the rupture zone (Wr) of individual debris-rockslides range from 28.21 to 1059.82 m and displaced mass (Ld) from 21.36 to 1197.95 m.
