Decade-Long InSAR Time-Series (2014–2024): Fault Kinematics and Seismic Hazards across the Minab–Zendan–Palami Fault System

The western structural boundary of the Makran Subduction Zone (MSZ) corresponds to the Minab–Zendan–Palami (MZP) dextral strike-slip fault system, a critical transitional zone that accommodates the velocity gradient between the Zagros and western Makran regions. This study investigates the kinematic behavior and mechanisms of the MZP fault system to enhance our understanding of fault dynamics and their implications for seismic hazards and subduction-zone processes. Continuous monitoring is essential to advance our knowledge of this complex fault system. However, the existing GPS network lacks the density \ necessary for effective fault monitoring. To address this knowledge gap, Synthetic Aperture Radar (SAR)-based analysis is well-suited for studying the MZP fault system. This study applies the Small Baseline Subset (SBAS) method to a decade of SAR data from the ascending path (57) of Sentinel-1A (2014–2024). The results detect and quantify subtle crustal deformations and fault kinematics with high precision. We classified the fault system motions based on their displacement characteristics. In conclusion, this research makes significant contributions to the fields of geodesy and geodynamics by refining our understanding of fault systems at tectonic boundaries and providing critical insights for seismic hazard assessments in this tectonically complex and seismically active region.
