This study focuses on determining the orientation and constraining magnitude of present-day stresses in Dezful Embayment Iran’s Zagros Fold Thrust Belt. Two datasets are used: first includes petrophysical data from 25 wells (3 to 4 km deep), second contains 108 earthquake focal mechanisms, mostly occurring blind active basement faults (5 20 deep). Formal stress inversion analysis mechanisms dem...

The morphological boundary between the Himalayas and foreland plain is well expressed most often corresponds to frontal emergence of Main Himalayan Thrust (MHT). This affected by surface ruptures during very large earthquakes (Mw > 8) that regularly induce (with a recurrence order 500 1200 years) uplift foothills relative plain. However, thrust-fold system hidden beneath displayed seismic profi...

The Sulaiman Fold Thrust (SFT) in Central Pakistan formed during the India-Eurasia collision late Cenozoic. However, mechanics of shortening brittle crust at time scales seismic cycles is still poorly understood. Here, we use radar interferometry to analyze deformation associated with 2015 magnitude (Mw) 5.7 Dajal blind earthquake eastern boundary SFT. We kinematic inversions determine distribu...

The Apennines are a retreating collisional belt where the foreland basin system, across large domains, is floored by subaerial forebulge unconformity developed due to uplift and erosion. This overlain diachronous sequence of three lithostratigraphic units made (a) shallow-water carbonates, (b) hemipelagic marls shales (c) siliciclastic turbidites. Typically, latter two have been interpreted reg...
