Based on landslide scaling relationship, we observed that a transition zone exists in the NW Himalaya that differentiates the landslide volume capacity of the hillslopes and possibly landslide frequency.
The most probable reason could be spatial variability of the Indian Summer Monsoon that depletes in the Indian Himalaya in a ESE-NW direction. The other potential reason could be seismic activity. My question seeks the explanation in seismic context.

Thank you Tadeusz Tumalski .
I read this interesting article. However, i am still looking for more detailed explanation of spatial variability, if any, in NW Himalaya. As i understand, the possible mechanism in this region could be structural variation in the Main Himalayan Thrust (MHT) ramp.
Thank you R. Arun Prasath .
I will read these articles and will let you know for further, if any, query.
Thank You.
I would recommend this chapter by Professor Bilham on Himalayan earthquakes. https://sp.lyellcollection.org/content/early/2019/01/31/SP483.16
