Abstract:
This report contains the estimation of the ground motion in terms of peak ground acceleration for the Kangra earthquake of 1905. The estimation of PGA is done by two methods for the same earthquake primarily by D.S.H.A. (Deterministic seismic hazard analysis) using ground motion prediction(GMPE) equations by ArcGIS move toward to obtained the PGA values to attain seismic hazard assessment and secondly using intensity empirical relation to obtain seismic hazard assessment by estimating the PGA value and then at last using NGA method to obtain the PGA values and the compare the methods to drawn the best performing approach for ground motion observation. There are some attenuation relationships used to get floor action like Jain et al.(2000), Fukushima & Tanaka(1993) and Akkar and Boomer(2007). Intensity based relation is being taken. In this file GMPE relationship used is Jain et al. (2000). This relationship is pretty appropriate for Himalayan earthquakes and north west Indian earthquakes. In this work a rectangular vicinity of 2°24’*1°36’ is viewed to be taken of Kangra area and shaped a framework of several grids .A series of factors had been given at everynode of that grid. The formation of grid is carried out with the ArcGIS 10 software. The statistics for PGA is accumulated at each points like distance Rjb from fault line to each node or point ,latitudes longitude and soil type etc. The figure are generated the use of this facts which are displaying ground motions of that area. The calculated ground action then Compared to recorded most peak floor acclearation this Earthquake. The most important objectives of this thesis to learn about to estimate high ground acceleration using GIS approach in kangra region and perfect scenario of ground motion in soil type and rock type of site.
