Abstract
Che Ju Do is a volcanic island off shore from the Korean Peninsula. The island is an extinct volcano, petrologically a part of the intra-pacific province of the olivine-basalt-trachyte association. The last volcanic activity has been reported in old manuscripts. Climate of the island is primarily influenced by the Pacific monsoon pattern and the north-west winter Siberian winds. A highly permeable basaltic surface of the mountainous central part of the island, coincident with the highest precipitation in the area, results in good recharge of ground water. Ground water appears as perched horizons on impermeable planes between lava flows, but most of the reserves are stored in a basal fresh water lens, which floats upon and displaces the sea water beneath the island.
