Using the empirical Green’s function method we simulated the January 13, 2001 earthquake using strong ground motion data (accelerograms) and an aftershock with magnitude Mw= 5.7. We used source spectral fitting method in order to find an estimation of parameters to be used in EGF method.
Two fault plane models determined by previous studies were considered for the simulation in this study. One has strike/ dip/ rake angles 306.°/ 48.°/ -107.° and another 297.°/ 58.°/ -93.°, respectively. For the former we tested two possibilities with the same asperity area (30 km x 30 km) but different number of subfaults.
We performed the ground motion simulation for three stations with large PGA and PGV values and a clear directivity pulse. From the result we determined that the former fault model provided us with the best results obtained in this study. This fault model is composed by a grid of 36 subfaults with individual area of 5 km x 5 km.
