Abstract
Areas with low deformation rates, such as continental interiors or mature orogens, may represent significant seismic hazard zones, albeit still insufficiently recognized. Relatively low-magnitude earthquakes occurring in such regions pose challenges for paleoseismology, despite occasional documented surface fault ruptures. This study focuses on a scarp located in the Podhale Basin (Central Western Carpathians) that deviates from empirical displacement-length scaling relationships. Despite its relatively short length of only 3 km, the scarp, measuring 4 m in height, presents several indications of its tectonic origin, yet to some extent scarp height could have been exaggerated by creep of weathered clays. Geophysical GPR and ERT surveys revealed a vertical discontinuity directly beneath the scarp. Moreover, we identified distinct features interpreted as a fault zone in a trench across the scarp. Lacking material suitable for dating, we estimated the age of the fault scarp at 10–50 ka using simple linear diffusion modeling. However, this result requires caution due to assumptions like scarp formation from a single event. Yet, the consistency of the estimated age with the superposition of the scarp relative to the morphology and weathered covers from the last glaciation is noteworthy. Furthermore, morphological and geological mapping suggests dextral oblique kinematics of the studied fault. The prevailing trend of NE (NNE) compression across the Podhale and Orava basins and the Tatra Mountains aligns the dextral Brzegi fault with the broader Alpine-Carpathian geodynamic framework. The Brzegi fault, as part of the broader Białka fault zone, provides evidence of far-field effects, serving as an NNW-striking dextral antithetic fault to major sinistral NE-SW striking faults. The recognized pattern indicates the continued post-Miocene Alpine extrusion towards the Carpathians.
