The main content of this data resource is the vector data of intensity at different time intervals from 0.5 hours to 1 day after the Jiuzhaigou earthquake. The data show the changes of the area affected by the earthquake on the surface and engineering buildings at different time nodes, which can roughly judge the change trend of the area affected by the earthquake on the surface and engineering buildings with time.

Statement of use: the intensity circle vector data 3 of the Jiuzhaigou earthquake disaster area in Sichuan Province in 2017 comes from the national key research and development plan project "Research on key technologies for rapid post earthquake disaster investigation of satellite aircraft ground coordination" (2017yfc1500900); Way of quotation: zhanglifu Institute of aerospace information innovation, Chinese Academy of Sciences Intensity circle vector data of Jiuzhaigou earthquake disaster area in Sichuan Province in 2017 3.2017
