Finite Source Simulation of Near-Fault Strong Motion Records from the 1999 Chi-Chi, Taiwan Earthquake

The stochastic method for finite fault is applied to simulate near-source ground motions from the 21 September 1999, Mw 7.6 Chi-Chi, Taiwan dip-slip earthquake. We simulated accelerograms, peak ground motions, and response spectra from 35 strong motion stations within a distance of about 10 km from the ruptured fault plane. The simulations are in good agreement with the examined records. However, the stochastic predictions are better constrained at distances >1.5 km. This primarily is attributed to the significant near-fault effects at the close vicinity of the ruptured plane related to this earthquake.
