The Chaman Fault is a major, active geological fault that runs over 850 km through Pakistan and Afghanistan. It is a primarily transform, left-lateral strike-slip fault that separates the Eurasian and Indo-Australian tectonic plates. As the Indo-Australian plate moves northward relative to Eurasia at a rate of 10 mm per year or more, the Chaman Fault accommodates this motion through lateral displacement. In addition to transform movement, the fault also has a compressional component due to the collision between the Indian and Eurasian plates. Major earthquakes have been produced along the Chaman Fault system, including a 7.7 magnitude quake in 2013.
