以强震前电离层TEC变化的观测事实为基础,以天地同震理论、TEC的地球化学输送途径为前提,遵循气体上升的物理化学动力过程,建立强震断层逸出气体卫星高光谱溯源模型,按垂直分层和水平多尺度及多时间分辨率进行任务分解,最终以9个步骤完成震前震中区的目标识别,定位精度在5 km×5 km以下。
Based on the observation of ionosphere TEC changes before strong earthquakes, on the premise of the theory of space-earth co-seismicity and the geochemical transport path of TEC, following the physical and chemical dynamic process of gas rising, this study has established a satellite hyper-spectral traceability model for strong earthquake fault gases emission, which decomposes tasks according to vertical layering and horizontal multi-scale and multi-time resolution. Finally, the target identification in the epicenter area before an earthquake is completed by nine steps with a positioning accuracy of smaller than 5 km×5 km.
