STRONG GROUND MOTION ESTIMATION AT ISTANBUL (TURKEY) BASED ON A EARTHQUAKE SCENARIO: PRELIMINARY RESULTS

| 抄録（英）： |
We performed a broadband frequency strong ground motion simulation in the Marmara Sea region (Turkey), based on a fault rupture scenario and a source asperity model. The simulation is performed by combining a deterministic and semi-stochastic procedures. We introduce a high frequency radiation model that makes a smooth transition between a non-spherical to a spherical source radiation as the frequency increases. The asperity seismic moment and rupture parameters were obtained from an empirical scaling to the seismic moment. Three fault rupture models were considered; the Northern Boundary fault (NB) and the Central Marmara (CM) fault segments rupturing individually, and together. The results show that the NB fault alone generates larger PGV values in Istanbul than the CM fault. The CM fault however produces a strong SmS Moho reflection that increases the amplitudes in the Istanbul region.
