Análisis del nivel de riesgo-exposición a amenazas por movimientos en masa en el Barrio Comité Pro-Mejoras Santa Teresita de Conocoto, zona Valle de Los Chillos, Distrito Metropolitano de Quito.

Abstract

Santa Teresita de Conocoto neighborhood is located to the south east of the Metropolitan District of Quito, this area is part of the Eastern Slope of the Loma de Puengasí, where it is located in the deposit of old landslide, this neighborhood corresponds to an informal settlement and It is made up of 133 lots. The pseudo-static safety factors obtained at the level of each lot by the application of seismic load, in this case a PGA in Slide 6.0 allow to obtain a level of threat that was mapped. On the other hand, the Slide 8.0 version allows obtaining Newmark displacements with the integration of the Loma Prieta earthquake accelerogram of 1989, which allowed determining the degree of danger in the area. he physical vulnerability analysis was carried out by means of the construction of a building appraisal form provided by the Metropolitan Management of Risk Management, with which a qualification was generated for the buildings exposed to a mass movement, with which a level of physical vulnerability that was represented cartographically. In order to integrate the values obtained from the level of the threat and the level of physical vulnerability, a normalization of the factors that allowed to obtain the risk-exposure values in a range of 0-1 was made, with which the risk levels were generated exhibition that were represented cartographically on a 1: 1000 scale map, as a tool for decision making by the corresponding authorities.
