| Abstract: | We analyzed the thermal infrared images features and the annual variation features of brightness temperature using NOAA Satellite thermal infrared remote sense data of 1999,2003-2008.The results show: ①Different geological tectonic units,especially linear active faults display as clear linear high temperature anomaly belts on the thermal infrared images.Through comparative analysis of the thermal infrared images taken from many periods of time,we can obtain the active faults’ spatial distribution and patter and study the active tectonic.②The surface thermal infrared brightness temperature has the characteristics of spatial correlation,temporal continuity and annual variation period although it is influenced by many factors,such as terrain,weather and geological tectonics.Based on the statistical analysis and difference process of much data accumulated in many years.We can effectively acquire the thermal infrared brightness temperature anomaly and analyze the correlation between the anomaly and certain earthquake.(3) The brightness temperature along Taihang mountain fault is clearly higher than that in Huabei plain,where altitude is only about 20 m,which indicates that the Taihang mountain fault is a high temperature anomaly belt.The preliminary analysis concludes that the thermal anomaly belt is likely relative to geophysical anomaly existing beneath the Taihang mountain fault.We infer that thermal infrared anomaly phenomenon may appear in some geophysical anomaly belt. |
