对地观测技术用于汶川和玉树地震灾害的研究
Study of Earth Observation for Disaster Reduction in Wenchuan and Yushu Earthquakes
摘要
Abstract
Wenchuan and Yushu earthquakes caused heavy casualties and property losses. Right after the events, earth observation techniques were applied to disaster monitoring and assessment. This paper introduces three typical results of these two earthquakes. done by the Center for Earth Observation and Digital Earth (CEODE), Chinese Academy of Sciences (CAS).Firstly, optical earth observation techniques were used in deriving locations, spatial distribution and intensities of three important secondary geological disasters including barrier lakes, damaged transportation and collapses/landslides/debris flows. Secondly,Multi-mode Synthetic Aperture Radar (SAR) techniques were used to analyze the regional geological structures and lithologic distribution characteristics, and then obtain sizes and spatial distributionof coseismic deformation fields in heavily hit areas during the Yushu earthquake. Finally, 3D software system for disaster simulation and assessment was developed which provided accurate and effective ways for decision-making of emergency rescues and disaster relief.关键词
