摘要
The Daguangbao gigantic rockslide is located on the Gaochuan village, Anxia county.It is the hugest landslide triggered by the Wenchuan 8.0 earthquake on May 12 of 2008. This paper uses four periods of remote sensing data with high resolution before/after the earthquake and ground surveying and mapping data to analyze the basic features of the Daguangbao rockslide. The result shows the whole Daguang-bao gigantic rockslide is 4 300 m long, 3 500 m wide and 550 m thick in the maximum. The debris volume is about 1.15 ～1.2 billion m3. It is the hugest landslide not only in China,but also in the world in recent hundred years.
