Strong Ground Motion Simulation for the 16 September 1978 Tabas, Iran Earthquake
Abstract eng: Acceleration time history of horizontal earthquake ground motion has been generated to represent the motions experienced in eastern Iran from the 16 September 1978 Tabas earthquake by using of finite-fault simulation method. In this method, the finite source is represented by a rectangular plane, which is subdivided into a number of subfaults. The rupture begins from the hypocenter and spreads radially from it triggering the adjacent elements when it reaches its centre. The contribution from all the elements are lagged and summed at the receiver. The ground motion at an observation point is obtained by summing the contribution over several subfaults. Geometrical spreading, regional inelastic attenuation and site effects are included in the model. A good agreement is obtained between the simulated and the recorded data at frequencies of engineering interest which confirm the capability of this method in simulating of strong ground motions.
