Wang Haiyun,Xie Lili. A Review on Near-Fault Ground Motion Simulation[J]. Advances in Earth Science, 2008, 23(10): 1043-1049.

The ground motion is the outcome of a complicated system that consists of three physical processes (i.e., earthquake source rupture process, seismic wave propagation, and site response), and is simulated based on modeling the three physical processes. The ground motion simulation is a relative new discipline. New cases and problems discovered progressively in strong motion observation and lucubrated on them will further promote development of both theory and practice about near-fault seismology. The precision in ground motion simulation will be improved by both reducing uncertainties in models and substituting statistical characteristics based on observation physics for hypotheses based on some phenomena. The present situation of simulation methods of near-fault ground motion, methods of modeling three physical processes, and their trends are reviewed based on a lot of literatures and data on ground motion simulations.
