Seismic Hazard Assessment for the NTF by Slip Tendency Analysis based on the Regional Stress Extracted from the Focal Mechanism of Earthquakes and GPS Observables

The reactivation of slip on pre-existing planes of weakness is of key interest to many geological phenomena, being implicit for instance in tectonic inversion theory and in the concept of stick slip behavior. The analysis of reactivation is crucial in engineering geology where rock masses must be below the critical stress level needed to initiate sliding and in reservoir geology for selecting safe hydrocarbon traps. It also constitutes a valuable tool in seismic hazard assessment as it provides a means of quantifying the slip potential on mapped or suspected faults in a known or inferred stress field.
