摘要
对岫岩5.4级地震前震序列进行了重新核定,将该序列分为两段,前段震群为前兆震群、响应地震、广义前震,后段才为前震。我国的一些大震及辽宁的一些地震前均出现过类似地震。科学认定前震、响应地震、广义前震对实现岫岩5.4级地震短、临预报起到了重要作用。
By reevaluating the foreshock sequence of Xiuyan M5.4 earthquake, it can be divided into two parts. The forepart contains the precursor swarm, response earthquake and generalized foreshock. The last part comes to the foreshocks. This kind of phenomenon has appeared both before some large earthquakes and some earthquakes in Liaoning province. It is important to identify the foreshock, response earthquake and generalized foreshock in the short-impending forecast of Xiuyan M5.4 earthquake.
