Abstract

Jammu is a fast-growing and major city in northern India, in UT Jammu & Kashmir. Jammu, the winter capital, is a city of temples, a symbol of ancient values, and has a distinct image due to its legacy, geography, and connections. The present study focuses on Site Characterization through geophysical testing i.e., (Active) Multi-channel Analysis of Surface Waves. Multi-channel analysis of surface wave (MASW) is used for measuring the shear wave velocity (V_S) at twenty-one (21) locations within Jammu city using TROMINO. Shear Wave velocity profiles over 30 m depth have been generated at each location using Grilla Software. Using the V_S30values seismic site characterization of the locations has been carried according to National Earthquake Hazard Reduction Program (NEHRP) guidelines. V_S30 is a significant input for evaluating the seismic response of a soil deposit to earthquakes because it is a dynamic property of soils. The value of V_S30for the sites is varying from 271 m/s to 475 m/s. Site characterization revealed that most of the sites fall under C and D categories. From the V_S30values further a map was generated using a GIS platform that can be used for hazard estimation.
