摘要
本文讨论了當熟—太仓5.1级地震前,邻近地区曾多次出现小震震群,形成一个空区之后,在黄海“老震区”出现相对的波形异常。研究结果表明,这些空区和波形异常的出现,除了与地质条件有关外,还显示了出现主震前兆异常的可能性。
This article discusses some unusual phenomena: many small guake swarms had formed an earthquake gap in the region surrounding the Changshu-Taicang M=5.1 earthquake, and unusual waveforms appeared in the quakes of the Yellow Sea old earthquake region, which occurred before the M=5.1 earthquake. The results show that they are related to the local conditions of geology and seismology, and should be counted as precursors of the main earthquake.
