红河断裂带南段现今的实际活动强度和地震危险性状况存在两种观点，一种无震蠕运动，另种是目前处于强震闭锁，具有大震危险。本项目拟通过高精度、高密度的GPS 、InSAR观测，获取断裂带南段高时-空分辨率的地壳形变场图像，特别是断裂沿线“紧邻断裂两侧”地壳差异运动的时-空变化特征。在此基础上，结合多学科成果资料，研究解答“现今红河断裂带南段是无震蠕滑还是目前一直处于闭锁状态” 这一科学问题。

There are two viewpoints about the recent strength of actual activities and seismic seismic hazard situation on the southern section of the Red River fault. One is aseismic creep on strike-slip fault, and the other is a strong block state that has high seismic risk. In this project, we are planning to obtain a regional crustal deformation field with high spatial and temporal resolution, especially the near-fault crustal deformation characteristics along the fault zone, based on the observations of a dense GPS and InSAR. And then, based on the GPS and InSAR results, as well as the results from other other disciplines, to study and manage to answer scientific issue about “Aseismic creep or always in a strong lock state on southern section of RRF”.
