résumé

High-level geological disasters are characterized by strong concealment, strong destructiveness, and difficulty in investigation. These disasters have frequently occurred in the mountainous areas of Southwest China in recent years, thereby causing serious casualties and property losses to mountain residents. Remote sensing technology has the advantages of short response time, intuitive image, high resolution, and extensive monitoring range. An image is highly achievable, easy to obtain, low cost and reliable, and can be “acquired.” On the basis of the Gaofen-2 and TRIPLESAT (Beijing-2) images as the data source, this study conducted an emergency monitoring of the “10·11” Jinsha River high-level landslide and analyzed the landslide disaster situation, disaster evolution, and pre-disaster creep characteristics. The second investigation was performed after the disaster in the vicinity of a barrier lake. A total of 2 suspected cracks in the entire area of the barrier lake, 16 hidden dangers in the landslide, and 5 inundation areas were found. Results showed that domestic remote sensing satellites demonstrate considerable application prospects for the emergency monitoring of severe geological disasters.
