摘要
根据中国地壳运动观测网络工程获得的重力变化及强震活动性,介绍2008年新藏交界地区(36.0°N,80.0°E为中心,半径200km)Ms7.3地震中期预报的基本依据及重力场动态演化图像。
Based on the gravity variation data repeatedly measured in the Project of China Crust Movement Measuring Network and related stong seismicity, the authors had predicted in December, 2006 that an event of Ms 6 -7 would break out in the area with 36.0°N and 80.0°E as its center and 200 km as its radius during 2007 - 2008. This paper destribes the scientific basis and dynamic image of the gravity field on which the medium-term prediction was made.
