| The Characteristic of Current Stress Hot Field by Satellite Thermal Infrared Image in China |
| Prior to earthquake occurrence serving the current stress hot field by satellite thermal infrared scanner there are having horizontal and vertical stress hot field in the earth. There are the heat radiation more which depend upon the stress increasing. Take the earthquake surface fracture zones and the map of iso-intensity into the consideration, combine these data of GPS, focus moment solution and relax of stress, the current stress field is obtained correctly. Judge eastern and western part with its deep structure movement difference and a result of the crust-mantle left-lateral and right-lateral and up-flow on boundary of 99?～104?E. It was converging attack from both N and S sides. The N side is Sibire plate and S is India plate. The force from the N will be at an end of Tianshan mountain. The Sibire plate and Pacific Ocean plate are revolving each other. The difference of the crust-mantle uprush in the western part of China reflects on the left up flow in the deep crust. The Sibire plate and Pacific Ocean plate are revolving each other. There is extensional structure in the north part of eastern part of China. Along these fracture NE, NNE direction occur right lateral movement that means New Neocathaysian. The difference of the crust-mantle uprush in the eastern part of China reflects on the right up flow in the deep crust. |
