Scenarios of Losses and Real Time Maps of Damage by Building Level for Mexico City

Abstract eng:
In this work we present a procedure to obtain scenarios of losses and real time maps and damage results building by building for Mexico City. This is possible due to the availability of seismic hazard modeling including site effects for the lakebed zone, given the source and the magnitude of the earthquake or the strong ground motion at a reference site, and the structural information of all buildings in the city. This building information comes from the city tax database and it includes geocoded polygons of each structure, number of stories, year of construction and quality of maintenance. This allows us to compute scenarios of losses to first identify those buildings at the highest risk and then to propose to the authorities emergency planning options and mitigating measures. We also take advantage of the already working shake maps technology to add real time building by building estimation of losses. We present an example with maps of the central part of the city for a postulated earthquake similar to the 1985 Michoacan earthquake.
