The distance range upto 5 km and the magnitudes ranging between 0 and 3 have been used for the development of the attenuation relationship. Two steps multiple regressions have been made by analyzing the decay of individual magnitude classes with distance using it with the whole data set. The model used in the present study is log (A) = c1 + c2M – c4 blog (X +ec3M) Where y is the peak ground horizontal acceleration, X is hypocentral distance and m is local magnitude ML, and ci’s and ai’s are regression coefficients. The discussions of the attenuation characteristics of the ground motion at shorter distances and low magnitudes have been discussed. The comparison of strong ground motion at similar distances using relationships developed from higher magnitudes reveals the difference in the observed peak ground horizontal accelerations with respect to the strain levels involved in the generation of the respective earthquakes.
