The Talas Fergana Fault is a major geological feature that traverses nearly the entire Tien Shan mountain system. It is characterized by large-scale horizontal movements of the Earth's crust.1

Geographically, the fault runs along the northeastern slopes of the Fergana Kyrka Mountains and extends toward the northwest. It is one of several deep faults in the region associated with significant seismic activity, including catastrophic earthquakes that have historically impacted areas such as Chatkal and Khait.1
