1986年5月14日至10月18日,成都市邛崃县南西银杏乡一带发生了一系列地震,其中,2.5级以上的地震27次,3.0级以上的地震12次,最大地震为5月27日7时12分发生的4.2级地震。虽然这次地震强度不高,波及面不广,但经过我们认真地分析研究后,却发现存在一些令人感兴趣的现象和带有某些规律性的特征,这也许对认识一个地震序列在发生、发展的全过程中所存在的某些规律有一定的帮助。
From May 14 to October 18, 1986, a series of earthquakes occurred in the area of Ginkgo Township, Southwest of Xuyi County, Chengdu. Among them, 27 earthquakes above 2.5 magnitude and 12 earthquakes above magnitude 3.0 occurred on May 27 Earthquake took place at 7.12 on the 4.2 magnitude earthquake. Although the intensity of this earthquake is not high and its spread is not extensive, after careful analysis and research, we found some interesting phenomena and some regular features, which may be of great help in understanding a seismic sequence Occurrence and development of the whole process of the existence of certain laws have some help.
