Land subsidence is an anthropogenic hazard triggered by different causes, one of them is groundwater overexploitation over aquifer systems, becoming risk points for aquifer pollution The obtained results showed that the Schlumberger configuration appears to be more helpful to detect changes in the stratigraphy toward depth, while dipole-dipole and Wenner are more suitable to detect lateral variations such as the vertical wastewater leakage in the first 6 to 8 m depth.

This paper studies the appearance of low-magnitude earthquakes linked to rapid movements of subsidence-related faults in the Aguascalientes valley. A particular seismic event is studied and occurred in the normal ancient Oriente Fault whose rapid movement was captured with PSInSAR.

Aguascalientes valley, located in the central part of México, is affected for a land subsidence process triggered by groundwater withdrawal. The resulted P-wave velocity models show a low-velocity anomaly within the fracture trace with widths from 50 to 100 meters. This anomaly is interpreted as a mechanically disturbed zone due to the activity of the surface fault, this is, due to the presence of fracturing caused to the adjacent material by the differential subsidence.

The organization and working way of an interdisciplinary and intragovernmental committee to face the effects of the land subsidence related ground failures in Aguascalientes State, México is showed. The committee is composed by federal, state, and municipal governmental agencies, as well as privet and civil associations, and the state university, working split in four groups to manage the risk related to ground cracks and surface faults.

This research contributes to the understanding of surface deformation in the study area with new knowledge of the upper soil sequence. An established sequence distribution of the shallow layers was set and some of their geotechnical properties were determined. The analized samples are composed by compressible clayey silt and several lenses of volcanic sandy ash. Heterogeneities may be contributing to differential subsidence which is controlling the occurrence of surface faulting.
