摘要
介绍下关34井气氡测点及资料对应地震情况,针对2007—2010年气氡观测资料几乎每年相同时段出现的高值异常现象,结合该井水温、降雨、湿度、水位及可能出现的影响因素分析,认为异常可能是由于湿度和集气容积随水位变化与地震前兆异常叠加的结果,为判别气氡异常提供参考和借鉴,以利于提高气氡观测质量及在地震分析预报中的应用。
In this paper, we introduce the basic observing condition and anomaly features of gas radon derived from No. 34 well in Xiaguan. The relationships between high Rn values and earthquakes, rainfall, waterlevel, water-temperature and other factors are analyzed. We found that the high Rn value are mainly related to rainfall, waterlevel and possibly to precursory anomalies before earthquakes which occurred near by this well. This result may helpful for promoting digital observing quality of gas Rn and predicting earthquake with this kind of data in future.
