Abstract In order to set up the absolute gravity datum of China Earthquake Gravity Network, we have surveyed 12 fiducial stations in China mainland from March to June,2007 using FG5/232 absolute gravimeter, and obtained high accurate absolute gravity data. The comparison and analysis show that the standard deviation of result is less than ±2×10 -8 ms -2 except Urumchi station.
Key words ：
earthquake gravity network
gravity datum
absolute gravimeter
gravity measurement
repeatability
