Susceptibilidad a procesos de remoción en masa: Aproximación metodológica para la construcción de un índice de amenaza en Álvaro Obregón-Ciudad de México

This article presents a methodological approach for the evaluation of the hazard, by means of an index that determines the landslides for susceptibility and its hazard levels in the rainy periods, based on mixed method (qualitative and quantitative), derived from a Doctoral research, on the configuration of risk in peri-urban spaces in Mexico City. A multifactorial summation was used that combines determining and triggering geomorphological and morphometric parameters in the occurrence of MRP, applied in the borough of Alvaro Obregon- to the west of Mexico City, given its high occurrence of disasters in Mexico. Diverse factors were evaluated such as: lithology, land use and vegetation, geomorphological categories, slope, hillside geometry, relief energy, and as a trigger, rain, by means of the maximum historical monthly rainfall of the rainy half of the year (may-october). The result determined that more than 50% of the territory is susceptible to MRP, particularly in the three months with the highest intensity of rainfall. This result serves for the theoretical and methodological discussion for the knowledge of the multi-criteria evaluation of hazards as a main contribution in the construction of risk scenarios and their management.
