3. Remote Sensing Monitoring of Dammed Lake in Tangjiashan, Beichuan County, Sichuan ProvinceInstitute of Space and Earth Information Science, The Chinese University of Hong Kong collaborated with The Taiwan University in monitoring the change of dammed lake in Tangjiashan. They performed this by comparing the Taiwan FORMOSAT-II satellite image in 14th May, 2008 and 18th May, 2008. There was a magnitude 8 earthquake on Wenchuan County, Sichuan Province (latitude 31°, longitude 103.4°) at Beijing time 14:28, 12 May. It caused large area of landslides on the mountains in Beichuan County. Dammed lake is formed in Jianjiang, Tangjiashan and it posed serious threat to the downstream regions. As analyzed form the images, the largest width of Jianjiang was about 230m in 14th May. Until 18th May, that width of the dammed lake has already reached 540m. The water surface area at Xuanping Jiangzu Township was increased obviously. So far, the danger has not yet lifted. (as below) 
4. Monitor and Assess the Damages of Sichuan Earthquake using Satellite Images – Estimation of Building Damages in DujiangyanThe Institute of Space and Earth Information Science of the Chinese University of Hong Kong collaborated with the Beijing SPOT Image Co., Ltd. and carried out the building damages assessment in Dujiangyan. The Project Team compared two satellite images, a Germany TerraSAR X-band 1m resolution radar image (taken on 16th May 2008) and a Quickbird Optical Satellite Image (taken on 23rd August 2008), and assessed the degree of building damages in Dujianyan. The Project Team found that the Magnitude 8.0 earthquake at Sichuan Wenchuanxian (Latitude 31.0º N, Longitude 103.4º E) on Beijing time 12th May 2008 14:28 resulted in massive buildings collapsed, more than 90% of the total buildings are damaged and about 15% of them belong to settlements. The worst case is found in Northeast and Centre Dujiangyan with more than 20% of houses were collapsed, while the housing damages in Eastern Dujiangyan are less serious (as below). 
On the other hand, the Wenchuan earthquake did not bring serious damages to the Dujiangyan Irrigation Project. It is observed that the bridges, reservoirs and dams did not pose any immediate threats to the public as found from the TerraSAR radar image and aerial photo.
