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] |
Lava Tubes
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

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] |
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).

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 ...
