Manjang Cave
The Manjanggul Lava Tube is located in Gimnyeong-ri, Gujwaeup, Jeju City. At up to 23 metres (75') wide, 30 metres (100') high and 8.928 km (5½ miles) long, it is the 12th-longest lava tube in the worldhttp://www.caverbob.com/lava.htm and the second longest on Jeju island. It is regarded as having significant scientific and heritage value, owing to its excellent condition of preservation despite its age of formation (about 300,000 to 200,000 years ago). Lava stalactites and lava stalagmites, lava columns, lava flowstone, lava helictites, lava blisters, cave coral, benches, lava rafts, lava bridges, lava shelves, grooved lava striations, and ropy lava are well-preserved. Among them, a lava column of 7.6 metres (25') is the largest known in the world. There are three entrances and No. 2 heading southward is open to the public. Entrance No. 3 contains the most favorable habitats for cave life and between Entrances 1 and 2, there is a lower level main tube where most of t ...

Geomunoreum Lava Tube System
The Geomunoreum Lava Tube System is located between Seonheul-ri, Jocheon-eup and Weoljeong-ri, Gujwa-eup, Jeju City, Jeju-do. This lava tube system refers to a series of lava tubes formed while basaltic lava flow which had erupted several times from the Geomunoreum volcano (which has an elevation of 456m) flowed in a north-northeast direction, down to the coastline for about 13km. It is estimated that it was formed between about 100 and 300 thousand years ago. Lava tubes so far included in the Geomunoreum Lava Tube System are the Seonheul Vertical Cave, Bengdwigul Lava Tube, Bukoreumdonggul Lava Tube, Daerimdonggul Lava Tube, Mangjanggul Lava Tube, Gimnyeonggul Lava Tube, Yongcheondonggul Lava Tube, and Dangcheomuldonggul Lava Tube towards the sea. However, it is estimated that more tubes will be found. Bukoreumdonggul Lava Tube, Mangjanggul Lava Tube and Dangcheomuldonggul Lava are designated as natural monuments. Although these lava tubes are extremely large and ancient, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gimnyeonggul
The Gimnyeonggul Lava Tube, located in Donggimnyeong-ri, Gujwa-eup, Jeju City, is one of the World Heritage Sites in South Korea. The lava tube is about 705 m long, and is believed to be separated from Manjanggul Lava Tube by lava flows. The upper part of entrance is 12 m high and 4 m wide and is bent in a collapsed S shape. The upstream end of the passage was sealed with subsequent lava flows. The downstream passage is bi-level and the entrance is filled with sediments, most of which are carbonate sediments that had flown in from the beach. This is understood to be why there are lime features. The upstream end part is covered by a rich natural forest and the other end is covered with sand dunes. There is a significant amount of sand inside the tube. Because very little organic material has infiltrated the tube, Gimnyeonggul does not offer favorable habitats for cave life. Around 20 species are living in tube. The Gimnyeong lava tube is also called "Gimnyeongsagul" or "Sagu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hallasan
Hallasan is a shield volcano on Jeju Island in South Korea; it is the highest point of South Korea and the second-highest mountain in Korea overall, after Paektu Mountain. The area around the mountain is a designated national park, the Hallasan National Park (, ). Hallasan is commonly considered to be one of the three main mountains of South Korea, along with Jirisan and Seoraksan. Names Hallasan is the highest mountain in South Korea and is worshipped by people as they believe that gods and spirits live on the mountain. Alternate English names for the mountain include Hanla Mountain or Mount Halla and older English sources refer to the peak as Mount Auckland. Hallasan is written in Hangul as if it were ''Hanrasan'' (); however, it is still pronounced as ''Hallasan''. In the past, Hallasan has been known by numerous other names in Korean including ''Buak'' (/), ''Wonsan'' (/), ''Jinsan'' (/), ''Seonsan'' (/), ''Dumuak'' (/), ''Burasan'' (/), ''Yeongjusan'' (/), and ''Hyeolm ...

Seongsan Ilchulbong
Seongsan Ilchulbong, also called ‘Sunrise Peak’, is an archetypal Phreatomagmatic eruption#Tuff cones, tuff cone formed by hydrovolcanic eruptions upon a shallow seabed about 5 thousand years ago. Situated on the eastern seaboard of Jejudo, Jeju Island and said to resemble a gigantic ancient castle, this tuff cone is 182 meters high, has a preserved bowl-like crater and also displays diverse inner structures resulting from the sea cliff. These features are considered to be of geologic worth, providing information on eruptive and depositional processes of hydromagmatic volcanoes worldwide as well as past volcanic activity of Seongsan Ilchulbong itself. Geological characteristics Seongsan Ilchulbong Tuff Cone was formed by Surtseyan eruption, Surtseyan-type hydrovolcanic activity upon a shallow seabed about 5,000 years ago when the sea level was same as the present. Most volcanic cones or ''oreum''s (Jeju dialect for volcanic cones) were formed by piles of scoria cones which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeju Volcanic Island And Lava Tubes
The Jeju Volcanic Island and Lava Tubes is a World Heritage Site in South Korea. It was inscribed as one of the UNESCO World Heritage Sites in 2007 because of the Geomunoreum Lava Tube System and the exhibition of diverse and accessible volcanic features which are considered to demonstrate a distinctive and valuable contribution to the understanding of global volcanism. Jeju, also known as Jejudo, is a volcanic island, 130 kilometers from the southern coast of the Korean Peninsula. The largest island and smallest province in South Korea, the island has a surface area of 1,846 square kilometers. Formations 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. The main volcano includes 360 satellite volcanoes. Volcanic activity on Jeju began approximately in the Cretaceous and lasted until the early Tertiary period. The most recent eruptions are estimated to be about 5,000 years ago, which puts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of World Heritage Sites In South Korea
The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation or natural beauty, are defined as natural heritage. The Republic of Korea (South Korea) accepted the convention on 14 September 1988, making its historical sites eligible for inclusion on the list. , there are 15 World Heritage Sites in South Korea, and a further 13 on the tentative list. The first three sites of South Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Bent-wing Bat
The common bent-wing bat (''Miniopterus schreibersii''), also known as the Schreibers's long-fingered bat or Schreibers's bat, is a species of insectivorous bat. They appear to have dispersed from a subtropical origin and distributed throughout the southern Palearctic, Ethiopic, Oriental, and Australian regions. In Europe, it is present in the southern half on the continent from Iberia to the Caucasus, with the largest populations found in the warmer Mediterranean area. The common and scientific names honor Carl Franz Anton Ritter von Schreibers. Taxonomy There are 13 recognised subspecies of the common bent-winged bat. * ''Miniopterus schreibersii schreibersii'' * ''Miniopterus schreibersii bassanii'' (southern bent-wing bat): Found in southeastern Australia, this subspecies is critically endangered.Department of the Environment (2017).
