Urgent monitoring and analysis on Yushu Earthquake using remote sensing

At 7:49 am on April 14, 2010, an earthquake (Ms 7.1) originated (33.2°N, 96.6°E) near Jiegu Town, Yushu Tibetan Autonomous Prefecture, Qinghai Province, China. After the earthquake, we analyzed the geological structure of the disaster re- gion based on the "Beijing-1" images. Using the aerial images after earthquake with high resolution (0.4m) and SPOT or- tho-images, we monitored urgently the disaster situation, including the damage degree of the buildings, the damage degree of the lifelines, the field disasters and the secondary disasters. The result could provide the important basis for emergency management and rescue mission.
