摘要

对2009年11月5日西安高陵MS4.4地震的天体引潮力周期变化过程进行计算,并据该周期分析多源综合温度数据资料,提取地震过程的异常温度变化图像。结果表明:天体引潮力对地应力处于临界状态的活动断层具有诱发作用;震前温度发生明显异常,经历了起始增温-异常减温-温度恢复的演变过程。显示微震过程中天体引潮力作用明显,温度异常也有清晰反映,是地震热异常现象的有力证据,也是对利用热异常预测地震方法科学性的补充证实。
The cycle process of tidal force of celestial body for Gaoling MS4.4 earthquake near Xi'an city on Nov.5,2009 is calculated.According to this cycle the integrated multi-source temperature data are analyzed,and the abnormal temperature change images before the earthquake are gottern.The result indicates that the tidal force of celestial body has a triggering effect on fault activity.The temperature abnormal change can clearly reflect the procession of seismic fault activity: initial temperature rise→abnormally drop→return to baseline.It is shown that the effect of tidal force of celestial body on micro-earthquake activity is obvious and the temperature anomalies in micro-earthquakes are also clear.It is a good evidence for relationship between earthquake and thermal anomaly,and also for using geothermal anomaly to predict earthquake.
