Abstract
Past destructive earthquakes have provided the evidences of influence of local site condition on ground motions. The amplification of ground motion on the surface is strongly affected by the geotechnical characteristics of the region through which the seismic waves travelled. The present study is an attempt to assess the local soil effects in modifying the earthquake ground motion using one-dimensional ground response analysis for the central Gujarat region. The input parameters namely shear wave velocity profile, dynamic soil characteristics and ground motions are required to analyse the ground response at 66 locations of the study region. The results have been presented in terms of various maps, i.e., peak ground acceleration, predominant frequency and spectral acceleration. Based on the site characterisation response, spectra have been developed for the central Gujarat region. The results are also compared with the Indian Standard code. Site response study shows that the large amplification are observed in the ground motion at surface level as compare to rock level acceleration.
