Application of passive microwave remote sensing technology to the seismic prediction and its physical mechanism

A simulation experiment research of the application of passive microwave re mote sensing technology to the seismic prediction was carried out for rocks of different lithologic characters. The experiment was carried out under l oading condition during the isothermal process. The experiment results that the microwave radiation energy of the rock changes obviously with the chan ge of its stress state, These changes are caused completely by stress and h as nothing to do with temperature. So the stress state of the medium and th e microwave radiation energy changes of the medium are linked up directly i n physics. The discovery establishes the physical foundation and provides t he experimental basis for the observation of the stress field distribution on the earth surface layer and seismic prediction with passive microwave re mote sensing technology. Two physical mechanisms of predicting earthquake w ith passive microwave remote sensing technology are put forward in the arti cle, i. e. heat energy excitation mechanism and mechanical energy excitatio n mechanism. A method used to infer medium stress state and temperature sta te from passive microwave remote sensing detection is given in the article.
