摘要: 基于美国内华达大学地震实验室的矩张量反演程序,采用JAVA和HTML语言,研发了一套近实时全波形矩张量快速反演系统,用于区域台网地震矩张量的快速产出.该系统由区域地震速报系统触发,能自动实现中等强度地震矩张量的快速反演,同时也包含人机交互模块,可进行人工校正,最终以网页形式对外服务.本文将系统运行以来成功反演的结果与USGS和中国地震局地球物理研究所的计算结果进行对比,验证了该系统的可靠性.Abstract: Seismic moment tensor is an important part of seismology study, which supplies indispensable information for earthquake research. Fast acquisition of seismic moment tensor solution could be the key of post-earthquake relief and tendency determination. Based on the moment tensor inversion package from Nevada Seismology Laboratory, using JAVA and HTML language, we developed a near real-time full waveform moment tensor inversion system, which could fast output seismic moment tensor. Triggered by the Earthquakes Instant Messenger (EQIM), the system could inverse seismic moment tensor of moderate earthquakes automatically, also could be corrected manually, and offer web services in the end. Comparison has been made between our results and published ones by USGS and Institute of Geophysics, China Earthquake Administration, verifying the reliability of this system.
