Active faults in the west of the Lut Block (Central Iran)

Abstract

The western margin of the Lut Block, in southeastern Iran, has experienced many historical and instrumental destructive earthquakes where 13 earthquakes, from 1977 to 2020, totally had surface rupture with a length of roughly 207 km. In this study, we indicated active tectonic evidence of the fundamental faults based on the DEM terrain interpretation, and satellite data analysis with field data. We investigated surface evidence related to the activity of the faults and their depth characteristics. Our results of the geometric-kinematic characteristic of the faults have general applications in describing strike-slip faults, development of releasing, and restraining bends in positive flower structures.
