Abstract

A near field strong ground motion simulation was carried out due to fault rupturing in the Kocaeli Earthquake (1999). The ground motions are simulated by the convolution scheme in time for source function and in space along rupture direction with the layered soil Green's function method based on the kinematic dislocation model. The effects of the asperities in the fault rupturing are focused considering inhomogeneous rupture mechanism in terms of a multiple asperities. The synthetic motions based on the inversion information from the observed data are compared well with the YPT (Yarimca Petrochemical Complex) record of the Kocaeli Earthquake. The response spectrum results also show good agreement between observed and simulated motions. The wavelet transform analysis is applied to observe the variation of frequency contents with the time for recorded and simulated motions.

Near Source Strong Ground Motion Simulation for Kocaeli Earthquake (1999)

San Diego, California

A near field strong ground motion simulation was carried out due to fault rupturing in the Kocaeli Earthquake (1999). The ground motions are simulated by the convolution scheme in time for source function and in space along rupture direction with the layered soil Green's function method based on the kinematic dislocation model. The effects of the asperities in the fault rupturing are focused considering inhomogeneous rupture mechanism in terms of a multiple asperities. The synthetic motions based on the inversion information from the observed data are compared well with the YPT (Yarimca Petrochemical Complex) record of the Kocaeli Earthquake. The response spectrum results also show good agreement between observed and simulated motions. The wavelet transform analysis is applied to observe the variation of frequency contents with the time for recorded and simulated motions.
