The MBT was formed as a result of the collision of the Indian continent with Asia.
When the MBT initially formed around 10-25 million years ago,[1] it was a system of thrust faults which accommodated stresses from the compression of the continental collision which led to Himalayan uplift.
These faults accommodated stresses parallel to the MBT and helped the Himalayan mountains grow.
[4] The Main Boundary Thrust consists of multiple segments spanning 2,400 km (1,500 mi) in the Himalayas.
[8] At the western bank of the Bheri River, the fault slips at a rate of 0.75 mm (0.030 in)/yr.
