This study concerns the geomorphological and geological aspects of Sip-i-dong-pa-do which is consist of 10 separated islands located 38km west of Kunsan, Jeonbuk, Korea. Since these islands are mostly composed of various volcanic rocks, displaying in a circular structure, Sip-i-dong-pa-do may be formed by a cauldron subsidence. They exhibit a beautiful scenery including columnar joint, sea cliff and the other coastal features. Sip-i-dong-pa-do is, therefore, designated as quasi-preservation areas, considering their natural environment.
