Hello respected researchers,
I want to know that which one amongst Himalayan thrust faults (Himalayan Frontal Thrust (HFT), Main Boundary Thrust (MBT), Main Central Thrust (MCT), Martoli Thrust (MT) and Counter Thrust (MT)) shows highest strain rate at present.
What should be a probable reason?
The short answer to your question is - None of the Above. It is the Main Himalayan thrust (MHT) if you read Roger Bilham's ' paper suggested above. That too only the part of the MHT north of the Lesser Himalayan Duplex. In any case, geologically speaking MBT, Ramgarh Thrust (RT), MCT etc. are all old in-sequence faults which are dead now and cannot be slipping continuously at present. You could reactivate a part of these faults in out-of-sequence deformation during earthquakes though. MFT is believed to be the near surface equivalent of the MHT as is activated only during great earthquakes. GNSS studies reveal that it is not slipping at present.
@Malay_Mukul, Thank you very much sir for such an impactful answer.
If you consider the recent data, The MFT or Main Frontal Thrust is the most active fault. The areas where the thrust is lead by subsurface decollement e.g., in Pakistan. The salt occurs as a buffer zone.
Kindly refer to the following article for your further reference.
