泉州四至井水氡异常及中国台湾东南部(包括附近海域)地震的对应关系
|
摘要
对泉州四至井2006年1月至2008年12月水氡观测数据进行分析与处理,依据2倍中误差、短期阶升突跳、短期和中长期趋势异常等多种判别法,对其水氡异常进行判别。结果表明:泉州四至井水氡氡值基本保持春夏高、秋冬低的弓形年变化动态图像,出现的水氡异常对中国台湾东南部及附近海域有较好的对应关系,并对2006年7月28日花莲6.0级、2006年12月26日恒春7.2级、2007年9月7日台东6.3级地震进行案例分析,有关研究结果对寻求泉州四至井水氡异常对中国台湾地区某些敏感对应点的映震能力具有一定的现实意义。
Water radon observation data at Sizhi wells,Quanzhou from January 2006 to December 2008 are processed and analyzed.Based on some identifying methods such as mean square deviation, short-order step jumps and the short-term and long-term trends,the water Radon anomalies are distinguished.The results showed that the water radon in Sizhi well, Quanzhou keep an dynamic arc pattern as remained high in spring and summer and low in autumn and winter.The water radon data exception has the good corresponding relationships to earthquake in southeast Taiwan and the nearby sea area.Some case studies are carried out about the Hualian M_s 6.0 earthquake on July 28 2006,the Hengchun M_s7.2 earthquake on December 26 2006,the Taidong M_s 6.3 earthquake on September 7 2007 and other earthquakes with above magnitude of 6.The results is of practical significant to seek the response capacity of the water Radon anomalies at Sizhi well,Quanzhou to the earthquakes at some sensitive points in southeast Taiwan area.
