Dear RG members
I want to know from seismic or earthquake data about the relative activity of these faults either thrusts or strike slip faults.
With best regars

Ijaz,
I cannot provide you seismic data, but some is available in the literature. The major Himalyan-Karakoram faults (MCT, MBT, MFT, Salt R Th, Panjal Th, Indus-Zangbo sutute, Mkt) are considered as essentially thrust faults. Having said that, let us not forget the two major transform faults touching us--Chaman F and Karakoram F.
It depends on what you mean by "more" or "less" active. Rate (average) of motion? Something else? For me, a fault may be either active or not active. Other attributes describes properties of either active or inacitve fault, and by this they are of lower significance.
Hello,
We know that all three major types of faults exist in Himalayas, and all are active. Now, the question is which fault eats more food, time will tell, as more work comes out. With our current understanding about faults we know that faults survive because of deformation (stress is food for them). Just like we eat food. So generally, a big person will need more energy to survive, and thus bigger faults eat more food (via plate convergence etc). This is true of the frontal fault at the moment, which is the major active mega thrust.
Hope this helps.
Eat healthy to remain active!!!
