Abstract

Abstract

In order to resolve the long-time forward modeling instability and realize the long-time numerical simulation of natural seismic wave field, based on staggered-grid high-order difference method, the 2-D model partitioning way of M-PML is provided, the value of the M-PML absorbing boundary conversion coefficient P and its influence on the absorption capacity and the influence on effective signal made by truncation error are discussed, the 2D elastic wave long time numerical simulation using higher-order finite difference is realized. In addition, combining the data of the 5.5 magnitude earthquake which occurred in Hubei Badong on December 16, 2013 and its aftershock recorded by Wuhan and Zigui Seismograph Stations, the practical significance of the forward modeling method is verified. The results can provide a basis for the research of the propagation law, imaging, phase identification and hypocentral location of natural seismic wave field.
