Abstract
In order to study the geomorphological features of the wave cut platforms which are formed on the basalt, authors conducted a research on the four representative coasts of the Cheju Island, a southern most volcanic island of Korea. The study areas are as follows: Seogwipo coast in the south, Bugcheonri coast in the north, Seonsan coast in the east and Sinchangri coast in the west. All the coast are composed of basaltic ground rock. The Seongsan and Seogwiop coasts are composed of tertiary and quaternary formations as well as basalts. The wave cut platforms on all the coasts except the one in the north are composed of 5 terraces while the northern one 3 terraces. The highest terrace which may be called the 5 th terrace is covered with vegetations or sites of present human settlements. This terrace is not directly affected by the present wave planation and is usually severely weathered by the subaerial erosion and might be a paleo terrace. The height of this terrace near Seogwipo reaches 15 meters above mean sea level while it reaches 10 meters in the east and west coast and 5 meters in the north. This fact indicates that the Cheju Island was subject to the strong crusta] movement in the late tertiary and the early quaternary, during which time the middle part of the southern coast has uplifted ca. 10 meters in comparison to the northern one.
