嘉峪关断层气氡对祁连山西段中强地震的异常特征分析
|
摘要
主要利用嘉峪关断层气氡对1992年以来发生在祁连山中西段的一些中强地震进行分析探讨,说明嘉峪关断层气氡对发生在距嘉峪关地震台300km范围内的地震反映较灵敏。利用气氡主样五日均值与标准年动态对比图、日测值曲线,给甘肃省地震局提交了几次较成功的短临预报。
In this paper,we mainly analyze the strong earthquake in middle and western segment of Qilian Mountain with the anomalies of gas Radon of Jiayuguan Fault.The results shows that the gas Radon in Jiayuguan Fault is sensitive to the earthquakes occurred in no more far away 300 km from the seismic station.Using contrasted figure of 5 days mean of gas Radon and the standard annual dynamics,and day measure value curve,we have successfully submitted several times of shot-term to face forecasts to province department.
