The Himalayan Frontal Thrust (HFT) has experienced ruptures in the past due to multiple earthquakes, rendering it highly vulnerable to future seismic events. To accurately assess the risks associated with potential earthquakes, a comprehensive investigation of the regional subsurface structure becomes imperative. This study mainly employs ambient noise tomography along with controlled source seismology to estimate velocity distribution and the geometric characteristics of the HFT system in the Kumaon Himalayas near Pawalgarh, Uttarakhand. Upon analyzing the ambient noise data, we estimated that the Rayleigh wave group velocity ranging from 320 m/s to 1334 m/s. We also inverted the Rayleigh wave velocity to obtain shear wave velocity, a parameter of critical importance from a geotechnical perspective. Furthermore, we have performed travel time tomography studies using seismic data generated by thumpers and recorded with remotely acquired units (RAUs) and 5 Hz geophones. These studies reveal a low-velocity layer with P-wave velocities ranging from 1200–1800 m/s, measuring approximately 100 meters in thickness, and overlaying the Siwalik formation at an elevation ranges from 350-450 m. Seismic imaging has unveiled the HFT and the Kaladungi Fault (KF).
