A high dense gravity measurement composed of 323 sites was carried out in Amami-Oshima Island,Kagoshima,in order to reveal the detailed gravity anomaly distribution. The obtained distribution shows that Amami-Oshima Island has the positive anomalies ranging from +32～+66　mgal with a trend from NE to SW parallel to Ryukyu trench. The trend-reduced gravity anomaly distribution also indicates the northern and southern areas in the island with negative gravity anomalies.
