RODRIGUEZ VALDIVIA, Alan; TAPIA TOSETTI, Alejandro  y  ALBORNOZ ESPINOZA, Cristián. MASS MOVEMENT SUSCEPTIBILITYIN THE SOCOROMA VALLEY, ANDEAN PRECORDILLERA OF ARICA AND PARINACOTA. Diálogo Andino [online]. 2014, n.44, pp.25-39. ISSN 0719-2681.  http://dx.doi.org/10.4067/S0719-26812014000200004.

This article analyzes the susceptibity for mass movement in the Socoroma Valley, Arica and Parinacota region (Chile). Thispaper addreses the determinants of ground instability (lithology, slope, slope directions, structural lineaments, main drains distance, height, landslide inventory and Normalized Difference Vegetation Index). The result is the sectoring of susceptibility for landslides in the valley, according to the susceptibility index, obtained from the method Multi-criteria Evaluation with Analytical Hierarchy Process. Based on the results the mass movement, it was established that the Socoroma village is placed in an area of low susceptibility, while the south east sector of the considered area presents greater degrees of susceptibility; where the 11-CH international highway passes, the principal link between Bolivia and the coast of the Pacific Ocean, and the most important road connection between the Andean towns of the province of Parinacota with the lower valleys and the city of Arica.

Palabras clave : Susceptibility; mass movement; Socoroma valley.
