Collecting a dataset of debris flows in the China Pakistan Economic Corridor through literature review, using remote sensing images from 2022 to identify traces of debris flow erosion (such as river sediment, exposed rock surfaces, vegetation erosion, fan-shaped alluvial fans, and debris flow gullies) to verify the authenticity of debris flow data, and obtain historical debris flow events in the China Pakistan Economic Corridor. Based on the 2010 remote sensing images, compare the remote sensing images before and after the debris flow, observe the changes in surface features, identify debris flow events that occurred after 2010, and create a debris flow database for the China Pakistan Economic Corridor since 2010.

1. Collection of historical disaster data: Collect historical debris flow events in the China Pakistan Economic Corridor from various channels.
2. Verification of historical disaster events: Based on the latest Sentinel satellite remote sensing images, the authenticity of debris flow data is verified based on characteristics such as river sediment, exposed rock surfaces, vegetation erosion, fan-shaped alluvial fans, and debris flow gullies, and historical debris flow data of the China Pakistan Economic Corridor is prepared.
3. Verification of debris flow events since 2010: Combining remote sensing images from 2010, comparing the remote sensing images before and after the debris flow, observing changes in surface features, identifying debris flow events that occurred after 2010, and creating a debris flow database for the China Pakistan Economic Corridor since 2010
4. Improve attribute information: Utilize remote sensing technology to extract debris flow attribute information, including remote sensing images before and after debris flow occurrence, debris flow location, elevation, and slope, and establish a comprehensive debris flow database.
5. Interaction inspection and quality control: Further verify the reliability of events through interaction inspection.
The debris flow event has undergone strict quality control, and each event has corresponding remote sensing images and evidence, with a reliability of 100%.
