摘要：
A gravity survey was conducted one month after the 2010 Yushu earthquake in the epicenter area.The cross-fault survey line was 500 km long,from Langqian county to Qingshuihe county,in a transition zone between Bayan Har block and Qiangtang block,in an area of high elevation,large undulating terrain,and complex geological features.An interpretation of the data was carried out together with other kinds of data,such as seismic exploration and magnetic exploration.The result shows that gravity is sensitive to fault boundary;the geologic structure of the region is complex at middle and upper depths,and the density profile reveals an eastward-pushing fault movement.
