Abstract: In this paper, based on the cross-fault deformation survey and the result of comprehensive investigation of observation sites in the Capital area, we evaluate the comprehensive efficiency of whole baseline and level item, analyze and extract the integer movement information of faults, and study the efficiency of reflection for strong earthquakes in the Capital area of China. Using the observed results of the regional coverage of mobile gravity, we also analyze the dynamic variation characteristics of gravity field for the forecasting of the earthquake trend in the near future.

Key words: Fault deformation, Gravity field, Earthquake reflection efficiency, Capital area of China
