ULLUNG ISLAND

volcanic island, Kyongsang-puk do (province), South Korea. It lies in the Sea of Japan (East Sea), 75 miles (120 km) off the northeastern coast of South Korea. With the associated islands of Kkakse, Chuk, and Tok, Ullung Island constitutes Ullung county of the province. Before its domination by the Silla kingdom (57 BCAD 935) in 512, it was an independent kingdom named Usan-guk. The island has an area of 28 square miles (73 square km), and its summit, Songin Peak (3,228 feet ), has a caldera crater. The entire coastline has rocky bluffs 100300 feet high, which preclude port development. Neighbouring waters with the interchange of warm and cold currents offer good fishing ground for cuttlefish, which is exported, and various other marine products. Agricultural products, however, must be imported. The mountain area produces Chinese juniper, birch, and princess trees, all used to make quality furniture. Ullung-do is connected with Pusan and Jukbyon by regular sea routes. Pop. (1980) Ullung-gun, 18,960.
