Abstract
This paper presents use of the semi-empirical technique given by Midorikawa (1993) for simulation of strong ground motion due to great earthquake. Modification in this technique has been made in the present work to incorporate the effect of radiation pattern and seismic moment. The rupture model of Sumatra earthquake of magnitude 9.0 (Mw) which occurred on 26th Dec, 2004, is used as a test model for simulations due to great earthquake. The comparison of the simulated and observed record has been made in terms of ground motion record. Comparison establishes the efficacy of the modified technique for effectively simulating strong ground motions due to a great earthquake. The developed technique is applied to simulate strong motion record due to great earthquake from several probable ruptures in the vicinity of Andaman Island. Several simulations show that the Andaman region can experience peak ground acceleration of the order of 1.6 g due to any probable great earthquake.
