Theoretical analysis to impending tectonic earthquake warning based on satellite infrared anomaly

This paper briefly introduces the general scientific facts from the reports on satellite thermal infrared (TIR) anomaly before earthquake and the presented mechanism and hypothesis for interpretation the TIR anomaly. The spatio-temporal features of infrared (IR) radiation from loaded rock, stick-sliding rock and simulated active fault motion based on experimental IR detection are also introduced. Especially, the experiments on simulated fault activity shows that the TIR anomaly is likely to develop along the primary fault and the both sides of wedge-shaped acute geo-block in condition of intersected fault system, and that the intersection location is usually the coming epicenter. The theoretical mechanism of TIR anomaly before tectonic earthquake is hence suggested to be stress-thermal effect accompanied and strengthened by hydro-geological effect, greenhouse effect, P-hole effect and so on. As a case, the spatio-temporal features of TIR before Zhangbei Ms6.2 1998 earthquake is theoretically analyzed based on the overlay of active fault system on NOAA-AVHHR satellite TIR images. It was discovered that TIR anomaly is controlled by a potential great deep active fault and that the epicenter is exactly the intersection point of the primary great fault and two secondary faults being tow sides of an acute wedge-shaped active geo-block. It is concluded that although the earthquake is a complex and uncertain process of crust motion, the predication of earthquake is not impossible. Referring to the developing GEOSS and generalized remote sensing (GRS), a preliminary procedure for comprehensive multiple parameters analysis on fault activities and earthquake early warning is presented, which is based on massive data fusion.
