South Korea

It has been ages when I posted something here.Wel,l now I have a reason to do it.I received a card from Korea some days ago.And now I want to share it with you:)It is showing aerial view of Seongsan Ilchulbong Tuff Cone,It belongs to Unesco World Natural Heritage Jeju.

Jeju is a volcanic island formed during the fourth epoch of the Cenozoic Era. With its well-preserved geological features, the island is scientifically valuable for study of volcanic activities and subsequent lava cave formation. In 2007 the UNESCO World Heritage Committee inscribed the Jeju Volcanic Island and Lava Tubes on the World Natural Heritage List in recognition of their prominent scientific value and aesthetic scenery. The designation covered three sites-the Mt. Halla Nature Reserve, the Geomunoreum lava tube system and the Seongsan Ilchulbong, an archetypal tuff cone.
The World Natural Heritage in Jeju consists of three sites covering a total of 188.4 square kilometers, including some 187.2 square kilometers of land, which is 10.1 percent of the island' s total territory, and 1.2 square kilometers of publicly owned water surface. Mt. Halla (Hallasan) has a vast array of plant and animal species and superb natural scenery that features the crater lake Baengnokdam (White Deer Lake) on the top, fantastic cliffs and waterfalls. The mountain, rising 1,950 meters above sea level, has a unique vertical distribution of plants of diverse zones ranging from the subtropical, warm temperate and temperate to frigid zones.

The tuff cone of Seongsan Sunrise Peak, created by undersea volcanic eruption, has a dramatic landscape. The fortress-like peak, with its walls rising out of the ocean, has exceptional exposures of its structural and sediment characteristics, including the crater preserving its original shape. It is a world-class location for understanding the process of volcanic formation and Surtseyan-type eruptions.

The Geomunoreum lava tube system, regarded as the finest of its kind in the world, comprises a lateral volcano and five lava caves. They were created some 100,000-300,000 years ago when magma erupted from Geomunoreum and flowed through natural conduits slanted northeast toward the coastline, which are now empty caves displaying unique spectacles of multi-colored carbonate roofs and floors. Varying in length, structure and component, the five caves are Bengdwi Cave, Manjang and Gimnyeong Caves, Yongcheon Cave and Dangcheomul Cave. The Geomunoreum lateral volcano is Natural Monument.
