吉林省汪清两次深源地震的研究

本文在给出了发生在吉林省汪清的两次深源地震的基本参数、CMT解及有感范围等基本情况的基础上，总结了对2002年6月29日汪清7．2级深源地震的预测情况。对汪清两次深震前出现的水位、水化学异常进行了分析，初步认为异常可能与深源地震孕育过程中引起的大区域应力场调整有关。对6月29日汪清7．2级深源地震前长春净月地震台体应变仪记录到的前驱波机理进行了分析，认为对前驱波机理的研究，可能成为地震预测的一个突破点。

RESEACH ON THE TWO DEEP EARTHQUKES IN JILIN PROVINCE

Based on the earthquake parameter,CMT solution and sensible range of Wangqing two deep earthquakes in Jilin province were given,Wangqing deep earthquake of Ms7.2 on June 29,2002 was summed up in this paper.Analysing the change of the water level,water chemistry befor the two deep eearthquakes,it was considered that the anomalies contect with the big range stress field adjustment befor the two deep earthquakes.Analysing the mechanism of the procursor wave which was recorded by the Jingyue earthquake station before Wangqing deep eartheuake of Ms7.2 on June 29,2002,it was considered that the research on the pecursor wave will be a key of earthquake prediction.
