摘要
对新30号泉1990年1月1日至2009年5月31日水氡观测资料进行了统计分析。结果表明,新30号泉水氡观测点对温泉地区发生的5级以上中等地震映震效果较好,震前观测到一些异常信息,异常以高、低值脉冲型异常为主,破年变的异常比较可靠,而且均为短期异常。
The observation datum of water radon in new No.30 spring from Jan.1,1990 to May.31,2009 were analyzed.The result shows,the earthquake reflecting of water radon in new No.30 spring is good for MS≥5.0 earthquakes near Wenquan region,the abnormal characteristics is high and low value impulses,the abnormality which broken the annual change is credibility,and it is short term abnormality.
