Main Frontal Thrust

The Main Frontal Thrust (MFT), also known as the Himalayan Frontal Thrust (HFT) is a geological fault in the Himalayas 
that defines the boundary between the Indian and Eurasian Plates. The fault is well expressed on the surface thus could be seen via satellite imagery. It is the youngest and southernmost thrust structure in the Himalaya deformation front. It is a splay branch of the Main Himalayan Thrust (MHT) as the root décollement.
It runs parallel to other major splays of the MHT; Main Boundary Thrust (MBT) and Main Central Thrust (MCT). The Sunda Megathrust, which extends from the Banda Islands to Myanmar is jointed with the MFT. The fault strikes in a NW-SE direction and dips at an angle of 20° to 30° in the north. 
Main Boundary Thrust.
The Main Boundary Thrust (MBT) is another major thrust fault in the Himalaya orogenic wedge that was active in the Cenozoic. It runs parallel to the MFT with a spacing distance of about 20 km.
Shortening rate.
Shortening rate varies across the MFT, these figures provide the speed in various locations.
Seismic activity.
The MFT accommodates almost the entire rate of subduction of the Indian Plate therefore, it is no surprise that numerous earthquakes have occurred along this fault, and is expected to produce very big earthquakes in the future. Many earthquakes associated with the MFT has resulted in visible ground ruptures, as seen in the Bihar earthquake of 1934 and 1505 magnitude 8.9 earthquake.
