摘要
通过研究银川台小口子泉水氡多年观测资料在周边地区地震前的异常形态,发现资料的低值异常对应泉点西北方位的地震。通过研究震前异常形态的共性,结合观测规范,提出异常判定公式,并将以往的震例进行异常判定检验。在日常观测资料分析处理中,运用低值异常判定公式分析银川台小口子泉水氡观测资料出现的短临低值异常,比较成功的取得了两次会商、一次填卡短临异常预报。
This paper found anomaly data of water radon in Xiaokouzi spring which located at Yinchuan station before earthquake were valuable for earthquake prediction. They gave anomaly judgment formula before earthquake based on earthquake cases. They also made correct short term predictions through anomaly judgment formula for water radon.
