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.

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.

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.

This work presents the experimental and numerical results about a study regarding the performance of a full-scale thin-walled cold-formed steel building affected by ground differential settlements.

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.
