Delineating the near-surface geometry of the fracture system affecting the valley of Queretaro, Mexico

We present a combined Ground Penetrating Radar (GPIR) and geotechnical investigation of a fault-fracture system that affects the Valley of Queretaro. The main fracture, named Falla Central (FC), is aligned with north-south striking regional faults suggesting that the buried fault scarps influences the geometry and propagation of fractures. Although the origin of fracl uring is closely related to geological factors, in the urbanized area of Queretaro the mechanical and hydraulic equilibrium in the
