After “5•12” strong earthquake happened in Wenchuan, Sichuan Province, research workers from China Aero Geophysical Survey and Remote Sensing Center for Land and Resources went into action with the help of such units as the Air Force and the Headquarters of General Staff. They rapidly got access to the serious quake-hit areas such as Beichuan and Wenchuan and obtained aerial remote sensing data. Based on aerial remote sensing data in combination with data from Beijing 1st small satellites and CBERS-02B satellite, this paper describes in brief the results acquired from the investigation of barrier lakes caused by the earthquake.
