摘要
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 gotten. 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 a evidence for relationship between earthquake and thermal anomaly, and also for using geothermal anomaly to predict earthquake.
