Mechanics of the Kalabagh Fault, northwest Himalayan fold and thrust belt (convergence zone of India and Eurasia), using SAR interferometry and CFS

The Kalabagh strike–slip fault, which is characterized by right-lateral movement, part of the northwestern Himalayan foreland fold and thrust belt in Pakistan. This structure marks western eastern terminations Salt Range Surghar Ranges, respectively. No significant (>M6) earthquakes have been reported along Fault recent decades. Here, we take advantage space-borne Sentinel-1A SAR interferometry to gain insight into mechanics faulting, aseismic creeping, stress loading seismic cycle on spanning over approximately 7 years. In this study, also removed tropospheric effects using Generic Atmospheric Correction Online Service data from rate map. We further resolved LOS deformation both horizontal vertical deformations. Our Bayesian inversion indicates that fault experiences displacements. fault’s southern northern segments exhibit a creeping ∼4.2 ± 1.3 4.8 1.6 mm/year, respectively, while central section does not display any creeping. found confined between 0 ∼2.7 1.1 km depth at ∼3.9 faults. Nevertheless, ∼10 mm/year 0.5 6 segment fault. Moreover, our model resolve interseismic slip Fault. results affirm internal due presence thick salt layer decollement facilitates addition, Coulomb modeling depicts increases changes KBF.
