Earthquake prediction is an observation-based science. It is necessary to make further explorations of new observation principles and means while improving and perfecting the existing ones. One of these new explorations is study on the application of advanced remote sensing technology to earthquake prediction. In order to achieve this, we have conducted simulation experiments on rocks with different properties in the laboratory (in an isothermal loading condition). The experiments have revealed an obvious change of rock's microwave radiant energy wit h the rock's stress, which is totally caused by stress and irrelevant to temperature. This result directly associates the medium's stress with the change of the medium's microwave radiant energy physically, lays a physical foundation and provides experimental criteria for applying passive microwave remote sensing (PMRS) technology to the stress field distribution observation of the Earth's surface and the earthquake prediction. Presented in this paper are two physical mechanisms for applying PMRS technology to earthquake prediction, namely heat-energy excitation and mechanical-energy excitation as well as detection results by adopting the technology and inversion methods for medium's stress and temperature. |
