摘要
通过对辽宁省18项水化观测项目现状及映震效能的分析,发现盘锦水氡、岫岩水氡和汤池水氡对辽宁及周边地区应力场的变化反应较敏感,不仅在1999年岫岩5.4级地震前有较好的异常显示,对营海岫和唐山老震区的ML5级左右地震也有一定的指示意义。
By analyzing the earthquake reflecting performance with 18 hydration observation situation in Liaoning Province, it is concluded that Panjin radon, Xiuyan water radon and Tangchi radon are more sensitive to the changes of the stress field in the surrounding areas in Liaoning. There are not only better abnormalities before the Xiuyan M5.4 earthquake in 1999, but also some certain significance for ML5.0 earthquakes in Yingkou-Haicheng-Xiuyan area and the old Tangshan earthquake zone.
