摘要
1987年8月2日,江西省寻邬发生M_s5.5地震。本文研究了这次地震和震前的各种异常现象,研究发现,震前该区地壳形变和地震活动出现了中、长期同步变化,短临阶段,出现了异常地震活动和宏观现象。根据岩石破裂实验结果和地震前兆理论,对这次地震的孕育过程作了阶段性的划分。
On August 2, 1987, an earthquake with M = 5.5 occured in Xunwu, Jiangxi Province. The authors studied the earthquake and various anomalous phenomena before the event and found that both the crustal deformation and seismicity in Xunwu region exhibted the long- and middle-term synchronous varation; the short-term and imminent anomalous seismicity and macroscopic phenomena appeared then. Based on the results of rock fracture experiments and the theory of seismic precursors, the preparation process of the earthquake is divided into several stages.
