The Chaman Fault is a major, active geological fault in Pakistan and Afghanistan that runs for over 850 km. It is a system of related geologic faults that separates the Eurasian Plate from the Indo-Australian Plate. Tectonically, it is a terrestrial, primarily transform, left-lateral strike- slip fault, and it has a compressional component as the Indian Plate is colliding with the Eurasian Plate. The fault is slipping at a rate of at least 10 mm/yr, and it is one of the most prominent continental strike-slip plate boundary zones in the world
. The Chaman Fault system is located close to megacities in Pakistan and Afghanistan, and collision-related seismicity across this region has caused significant casualties
. The individual slip rates and locking depths of faults within the Chaman fault system are not fully known, and the fault is characterized by left- lateral strike-slip motion
