Resumen:
In the Zona Metropolitana del Valle de Mexico (ZMVM), subsidence and its
associated phenomena represent a critical problem in the region.
Particularly, soil fracturing constantly threatens infrastructure and
water quality. Thus, monitoring its occurrence and propagation is
paramount. In this work a methodology of analysis that allows
identification of soil fractures and understanding of their dynamics is
applied to the Penon del Marques area, southern ZMVM, where notable
subsidence and associated fracturing take place. Ground Penetrating
Radar (GRP) and InSAR temporal deformation evolution profiles are
integrated to interpret the phenomena acting and interacting in this
area. The present investigation indicates that profiles based on InSAR
time series can be effectively exploited to identify soil fractures and
the sliding mechanism in the area.
