We analyzed the gravity anomalies, by making use of gravity values of Korea and neighboring areas, in order to determine the flattening and gravity formula of the earth The conclusion, drawn from the result of the analysis, is as follows; 1. The gravity formula applicable to free air anomaly of Korea is γΦ =978033.67(1+0.005283574sin^4Φ )mgal and that to Bouguer anomaly is γΦ =978047.05(1+0.00543353sin^2Φ-0.000161749sin^4Φ )mgal 2. The flattening, calculated by the use of gravity values of Korea is 1/298.659. 3. It is thought that we can improve the regional property and accuracy of the contents of earth science by apply our results in the reorganization of earth science curriculum and instruction.
