By collecting post-earthquake remote sensing images of typical cities, towns and villages in different seismic intensity zones, we will analyze buildings (structures), lifeline engineering, infrastructures, earthquake damage degree and contributing factors of post-earthquake area on the image, investigate on-site and verify secondary geological hazards. Inadequacy of ground-based seismic surveys will slow down the research progress such as identification of seismic hazards, quantitative assessment, seismic intensity assessment and damage assessment. To solve this, we can use the low altitude UAV data to obtain fine-grained 3D ground data and complete the remote sensing images of earthquake-induced disaster contribution to further research.
