Estimating Shear Wave Velocity for Shallow Underground Structures in the Central Himalaya Region of Nepal: a Geophysical Study

EasyChair Preprint 14755

Abstract

Estimating shear wave velocity (Vs) is crucial for understanding the geotechnical properties of shallow underground structures, particularly in seismically active regions. This study focuses on the Central Himalaya region of Nepal, where complex geological conditions and seismic activity necessitate accurate Vs assessments for effective site characterization and earthquake risk mitigation. Utilizing a combination of surface-wave analysis and shear wave velocity profiling, we investigated various geophysical methods to estimate Vs in the study area. The research involved field surveys, including Multichannel Analysis of Surface Waves (MASW) and Refraction Microtremor (ReMi) techniques, to acquire empirical data on Vs profiles. Our results indicate significant variations in shear wave velocity across the region, reflecting the heterogeneous nature of the underlying geological formations. These findings contribute valuable insights into the subsurface conditions of the Central Himalaya, aiding in seismic design and construction practices. The study underscores the importance of region-specific geophysical investigations to enhance the reliability of structural assessments in seismically vulnerable areas.
