Análisis de riesgo por eventos de remoción en masa, propuesta de Plan de Mitigación. Ruta Nacional 40 sur, Lago Guillelmo, Departamento

Abstract

Addressing the issue of risk identification and management is of great interest to the State, planners, institutions and the population, since natural phenomena generate irreversible millionaire and environmental economic losses. To take prevention actions and develop protocols it is essential to have tools that contribute to the quantification of the same and its effects. Of all natural phenomena, mass movements, are in third place in the world with regard to the involvement of victims, compared to other natural disasters such as floods or earthquakes. The natural movements modify the relief and the original conditions of the slopes affecting the environment and the inhabited areas. In the area of Lake Guillelmo, active gravitational processes are observed, due to the intense weathering and fracturing of the outcropping rocks, added to the high slopes. The slopes have been eroded by ice during the ancient glaciations, a large number of debris generated by cryoclasticism, the presence of favorable collapse lithologies and structural weaknesses caused by the Andean orogeny
