Abstract

Slip distribution model has been developed for 15th January 1934 Bihar-Nepal earthquake of Mw 8.1 has been developed through stochastic model. The spatial variability of slip on the rupture plane is simulated as a random field with correlation lengths depending on the magnitude of the earthquake. The source dimensions have been computed from the scaling laws of Wells and Coppersmith (1994) and Mai and Beroza (2000). The slip distribution has been obtained from spectral synthesis method of Iguzquiza and Olma (1993) for both the source dimension. The slip distribution of each of the 5 samples has been shown in form of contour plots. The average slip estimated using different source dimension from WC and MB are 8.15 m and 12.96 m respectively. The simulated slip models developed can be used to simulate the displacement time histories of the 1934 Bihar-Nepal earthquake which can be used in seismic hazard studies in future.
