- •
Seismic coda wave attenuation characteristic has studied in the NW Himalayan region.
- •
132 seismic observations from 82 local earthquakes (Ml: 1.2–4.9) were used.
- •
Qc values increases with respect to lapse time and frequency.
- •
Low attenuation at higher frequencies shows that region is heterogeneous and tectonically active.
