IDENTIFICATION OF THE DANGER ZONES ASSOCIATED WITH LAHARIC FLOWS GENERATED BY THE ERUPTION OF THE CALBUCO VOLCANO

Abstract

The present work is based on the use of different technical-geographical procedures in the ArcGIS 10.3 program with the purpose of reconstructing risks scenarios of volcanic origin generated by the Calbuco Volcano. For this purpose, different forms, magnitudes and intensities of the eruption were modeled, and above all, diverse effects in the urban areas that interact with the volcano, as well as in distant areas that are affected by other processes of transport and dispersion of ashes and flows. This is part of a project to plan and analyze the risk factors associated with the various processes that act and are related during volcanic eruption situations, in which are derived various dynamics associated with factors of the internal composition of the volcano and external factors that are convened around the geographical conditions of the territory. It is an experimental, laboratory work and with possible use in hazard prediction.
