Abstract：By reviewing survey network changes and the summary of earthquake cases, we objectively expound the development process of Sichuan mobile gravity observation and its application efficiency in earthquake trend determination. The results show that the time-varying abnormal signals of gravity field such as high gradient zone, four quadrant distribution and zero line turning are observed by using mobile gravity data, and the Wenchuan, Lushan, Jiuzhaigou and Luding earthquakes in Sichuan-Yunnan prismatic block and boundary zone are accurately predicted in the medium term, especially in the determination of strong earthquake location, with an accuracy rate of 60%.
