Strong ground motion simulation of the 1970 MS 7.7 Tonghai earthquake, Yunnan, China

doi:10.7523/j.issn.2095-6134.2012.4.007

Abstract

Abstract: Using a composite source model, we simulate the strong ground motion from the 1970 Tonghai earthquake (M_S 7.7). Due to the lack of strong ground motion recordings and for verifying the reliability of simulated results,a finite fault model, developed based on the stochastic theory with the same input source parameters including fault slip distribution pattern and size, is additionally used to generate synthetic strong motion seismograms for comparison purpose. The acceleration time histories at four selected sites or cities, simulated by the two models, show good agreements in the amplitude, waveform, frequency content, and time duration within the 0.5-10 Hz frequency domain.

Key words: Tonghai earthquake, strong ground motion, composite source model, stochastic finite-fault modeling
