摘要

相似地震(similar earthquake)是指两次独立的地震所激发出来的地震波形具有非常高的相关性,其也称为波形地震对(earthquake waveform doublet)。目前使用相似地震主要用于相似地震震群的地震定位以及对地核的研究,其中地核的研究成果分别由宋晓东和温联星所获得,研究成果发表在Nature和Science上。
Similar earthquakes are the two independent seismic sources which generate the waveforms with high correlation,it also can be called as earthquake waveform doublet.The applications of similar earthquakes mainly concentrate on earthquake source location,as well as the study of the Earth's inner core,the important results in the study of earth core have been done by Xiaodong Song and Lianxing Wen respectively,which were published on Nature and Science.
