Zonificación de susceptibilidad de amenazas a escala 1:2000 por movimientos en masa e inundación a partir de las características geológicas, geomorfológicas y cobertura del suelo en el asentamiento 13 de Mayo en el municipio de San José de Cúcuta, Norte de Santander para su proceso de regularización y legalización.

Abstract

The municipality of San José de Cúcuta faces challenges in the management of hazards and its vulnerability due to the scarce information available, which in some cases is in the process of being updated in relation to detailed risk studies in its urban areas. The reserved statutes and the analysis of the land use plan reveal a structural behavior involving faults, anticlines, synclines and other structures, triggering natural phenomena such as floods and mass removal phenomena (MRF) on the land surface. In this context, an investigation focused on the human settlement 13 de Mayo, where a zoning by hazard susceptibility was carried out in order to facilitate the legalization and urbanization process through multitemporal analysis, geological and geomorphological mapping and detailed evaluation of surface geological units, as well as land use, land cover and hydrological parameters. These elements were used to characterize the surface units and served as the basis for the elaboration of an algebra of hazard zoning and risk assessment maps at a detailed scale of 1:2,000. This methodological approach follows the indications of Decree 1077 of 2015 for the scale of basic studies, in accordance with the soil classes established in Law 388 of 1997.; so that a general classification of phenomena by hazard susceptibility in a given range (high, medium and low) stipulated in the general charts for their zoning process is interpreted and analyzed
