Abstract
A satellite thermal infrared technique for short-term and impending prediction of strong earthquakes, by use of polar orbit satellites, geosynchronous satellite and meteorological satellites, combined with other satellites carrying scanners with infrared waveband, satellite receiving equipment and image processing equipment, in which the color density in a meteorological satellite thermal infrared map are divided into grades, which are adaptable to different seasons and latitudes. The brightness temperature data collected from infrared scanners are used to obtain the absolute temperature through atmospheric model corrections. The phenomena of temperature decreasing ring may appear over the cloud layers within the earthquake-pregnant region. Odd shaped clouds may appear in the sky over the earthquake-pregnant before quaking. When the earthquake occurs on a plateau region in the inland, certain thermal stress lines can be observed, the converging points of these thermal stress lines indicating the future epicenter.
