Risk assessment for earthquakes, debris flow and flooding in the ah 03 de octubre, in chosica, district of luringancho, Lima

Abstract

In the district of Lurigancho, in spite of being a district that presents many natural hazards, there are no risk evaluations in all its sectors of high and multiple exposure, which would lead to the impossibility of proposing control measures for such risks in these sectors, which would result in future damages and losses. The present study allows to deepen the knowledge of the risks associated with the AH 03 de Octubre (flood, debris flow and earthquake), so it will allow to generate semi-quantitative data on its vulnerability; and from the risk assessment to support the labor of decision makers at the local or regional government level. The methodology considered was based on the structure of the manual for the evaluation of risks originated by natural phenomena of the National Center for the Estimation, Prevention and Reduction of Disaster Risks (CENEPRED). The risk levels obtained for the hazards present were generally high, with some slight variations in the percentage of blocks, which shows that the AH 03 de Octubre has a highly vulnerable population.
