Abstract

Analysis of subsidence magnitude and its spatial variability through Differential Interferometric Synthetic Aperture Radar techniques in Mexico City has allowed us to generate a subsidence–related faulting hazard cartographic product. This study describes the generation of hazard maps through the derivation of the horizontal subsidence gradient and presents an example of this methodology on the northeastern area of the Mexico City Metropolitan Zone.

Keywords: DInSAR, subsidence, hazard, Mexico.
