...Ping He; Yangmao Wen; Yulong Zhong; Jianfeng Cai Abstract The occurrence of the devastating 2023 Herat earthquake sequence shattered a 1200 yr period of seismic quiescence in western Afghanistan. In this study, we utilize Interferometric Synthetic Aperture Radar (InSAR) data to derive the surface...

... near Herat and Kabul could indicate that the fault is intermittently active, but these earthquakes could also have occurred on nearby faults. The historical record in Afghanistan over the past 1,200 years delineates a tectonic view of the country plowing southward into the Arabian and Indian...

... of Afghanistan is dominated by several major shear faults that define a mosaic of blocks ( Wellman, 1965 ). These faults, the Herat, Akhbaytal, Helmand, Hari Rud, Sarobi, and Chaman faults, reflect major lineaments ( Figures 1 and 2 ) frequently containing ophiolitic complexes. In terms of modern tectonics...

In the area south of Herat, up to 1,000 m (3,300 ft) of schists with quartzite layers ( Blümel, 1967 ) resemble the Ordovician beds of east Afghanistan and are present between Devonian and crystalline rocks...
