The Jeju Volcanic Island and Lava Tubes
is a World Heritage Site
in South Korea
is a volcanic island, 130 kilometers from the southern coast of Korea
. The largest island and smallest province in Korea, the island has a surface area of 1,846 square kilometers.
A central feature of Jeju is Hallasan
, the tallest mountain in South Korea and a dormant volcano, which rises 1,950 meters above sea level. 360 satellite volcanoes are part of the main volcano. Volcanic activity on Jeju began approximately in the Cretaceous
and lasted until the early Tertiary
period. The last recorded volcanic activity was recorded approximately 800 years ago. The island is covered in volcanic rock and volcanic soil produced by Hallasan. Baengnokdam, the crater and lake in it are located at the peak of Hallasan, was formed over 25,000 years ago.
Jeju is scientifically valuable for its extensive system of lava tubes
(also known as lateral volcanoes or in Korean as Oreum
). These natural conduits through which magma
once flowed are now empty caves that are some of the largest in the world. The caves provide opportunities for scientific research and are also popular tourist destinations.Off the shores of the city of Seogwipo
are a vast belt of pillar-shaped rocks that are examples of the natural beauty of Jeju. Shellfish and animal fossils discovered in this area are also very valuable as scientific resources. Beomseom Island and... Read More
