Geodinámica del movimiento de ladera en el sector Cruz del Calvario de la ciudad de Zaruma provincia de El Oro, mediante la aplicación de métodos Geofísicos y Geodésicos.

Abstract

For the analysis of dynamic and geometric evolution of the slope movements it is necessary to know the development of the activity, location of scarpments, speed, volume and accumulation zones or reduction of the displaced mass. The present investigation aims the application of geophysical, geodesic and geotechnical methods; to determine the deformations variations and data analysis recorded in a period of time. The "Cruz del Calvario" slope movement is a traslational slide, characterized for presenting a slope morphology of 45°, constituted by tufas and thin particles of clays and highly weathered slimes. Two zones have been detected, the inactive one and the activate one with descending displacement from 0.47 to 0.8 m, with a maximum gradient of 0.774 m/year. The volume of mass displaced is 1.08 m3, affecting a surface of almost 46.2 m2. The analysis of the information determines that the displacement has direct relation with precipitation in rainy season due to the acceleration of weathering process and erosion of superficial deposits are and and anthropic actions of uncontrolled mining activities.
