摘要
对厦门台伸缩仪2004—2007年的观测资料作了质量评定,针对厦门地震台SS-Y型伸缩仪EW分量在2007年福建省内两次震前出现大幅度异常变化的情况进行分析,结果显示,虽然异常变化同两次地震对应较好,但不是前兆异常,而是由降雨引起的。
The data of SS-Y ensometer observed during 2004—2007 at Xiamen seismostation were assessed in quality and the analysis of the significant abnormal changes of SS-Y tensometer at Xiamen seismostation before two earthquakes occurred in Fujian province was made.The results show that these two anomalies were caused by rainfall,not be the earthquake precursory anomaly,although they were corresponding to the earthquake well.
