Collect a landslide dataset for the China Pakistan Economic Corridor through literature review, and use the latest Google Earth remote sensing images to identify surface evidence of landslides (such as sudden destruction of continuous landforms, obvious landslide walls, features of landslide tongues extending downward from the landslide body, abnormal changes in topography, vegetation, water systems, and landscape ecology caused by landslides) to verify the authenticity of landslide data and prepare historical landslide events for the China Pakistan Economic Corridor.

1. Collection of historical disaster data: Collect historical landslide events in the China Pakistan Economic Corridor from various channels.
2. Verification of historical disaster events: Based on Google Earth imagery, the authenticity of landslide data is verified through features such as sudden destruction of continuous landforms, obvious landslide walls, and the downward extension of landslide tongues from the landslide body, and historical debris flow data for the China Pakistan Economic Corridor is prepared.
3. Improve attribute information: Utilize remote sensing technology to extract attribute parameters of landslides, including landslide area, height difference between front and rear edges, landslide location, and front and rear horizontal distance, and establish a comprehensive landslide database.
4. Interaction inspection and quality control: Further verify the reliability of events through interaction inspection.
The landslide event has undergone strict quality control, and each event has corresponding remote sensing images and evidence. Considering some factors such as construction excavation and remote sensing interpretation errors, the overall reliability is better than 90%.
