库尔勒断层氡气观测及观测资料分析初探
|
摘要
简要介绍了库尔勒断层氡气测孔周围的地质构造条件及仪器设置，并对两年多的观测资料进行分析。认为Ａ道较好地记录到１９９５ 年３ 月１９ 日和硕ＭＳ５．１ 级地震及５ 月２ 日乌苏ＭＳ５．８ 级地震前的突跳异常；同时利用Ｂ道气氡资料与气温、气压作了多元回归分析，认为Ｂ道连续两年多出现的长时间、大幅度变化的异常现象主要是受气温、气压季节性变化的影响。
The geological structure around the observing bores of fault product gas Rn at Kuerle as well as the installation of radonscope are introduced briefly, and more than two years's bore log is analysed in this paper. It is though that A trace recorded the sudden jumps better before the earthquakes of Heshuo M S 5.1(May 19, 1995) and Wushi M S 5.8 (May 2,1995). In addition, after the multiple regression analysis of B trace data, temperature, and air pressure, it is believed that the long time, large amptitude anomaly at B trace is mainly caused by seasonal variation in temperature and air pressure.
