Liancourt Rocks
The Liancourt Rocks, also known by their Korean name of Dokdo or their Japanese name of Takeshima,; ; . form a group of islets in the Sea of Japan between the Korean peninsula and the Japanese archipelago. The Liancourt Rocks comprise two main islets and 35 smaller rocks; the total surface area of the islets is and the highest elevation of is on the West Islet. The Liancourt Rocks lie in rich fishing grounds that may contain large deposits of natural gas. The English name ''Liancourt Rocks'' is derived from , the name of a French whaling ship that came close to being wrecked on the rocks in 1849. While South Korea controls the islets, its sovereignty over them is contested by Japan. North Korea also claims the territory. South Korea classifies the islets as Dokdo- ri, Ulleung- eup, Ulleung County, North Gyeongsang Province, while Japan classifies the islands as part of Okinoshima, Oki District, Shimane Prefecture.

Liancourt Rocks Dispute
The Liancourt Rocks dispute is a territorial dispute between South Korea and Japan. Both countries claim sovereignty over the Liancourt Rocks, a group of small islets in the Sea of Japan which are referred to as "Dokdo" () in Korean and in Japanese. North Korea also claims sovereignty of the islands. The Liancourt Rocks have been administered by South Korea since 1952 by the Korea Coast Guard. This action was taken after the United States stated in the Rusk documents that the Japanese claim to the Liancourt Rocks would not be renounced in Japan's post-World-War-II peace treaty. In 1954, Japan proposed a reference to the International Court of Justice, which South Korea rejected, believing that the Liancourt Rocks are irrefutably South Korean territories, and thus should not be dealt through diplomatic negotiations or judicial settlement between South Korea and Japan. There are conflicting interpretations about the historical state of sovereignty over the islets. Kore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Of Japan
The Sea of Japan is the marginal sea between the Japanese archipelago, Sakhalin, the Korean Peninsula, and the mainland of the Russian Far East. The Japanese archipelago separates the sea from the Pacific Ocean. Like the Mediterranean Sea, it has almost no tides due to its nearly complete enclosure from the Pacific Ocean. This isolation also affects faunal diversity and salinity, both of which are lower than in the open ocean. The sea has no large islands, bays or capes. Its water balance is mostly determined by the inflow and outflow through the straits connecting it to the neighboring seas and the Pacific Ocean. Few rivers discharge into the sea and their total contribution to the water exchange is within 1%. The seawater has an elevated concentration of dissolved oxygen that results in high biological productivity. Therefore, fishing is the dominant economic activity in the region. The intensity of shipments across the sea has been moderate owing to political issues, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Korea
North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia. It constitutes the northern half of the Korean Peninsula and shares borders with China and Russia to the north, at the Yalu (Amnok) and Tumen rivers, and South Korea to the south at the Korean Demilitarized Zone. North Korea's border with South Korea is a disputed border as both countries claim the entirety of the Korean Peninsula. The country's western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Pyongyang is the capital and largest city. In 1910, Korea was annexed by the Empire of Japan. In 1945, after the Japanese surrender at the end of World War II, Korea was divided into two zones along the 38th parallel, with the north occupied by the Soviet Union and the south occupied by the Unit ...

Overharvesting
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swell (ocean)
A swell, also sometimes referred to as ground swell, in the context of an ocean, sea or lake, is a series of mechanical waves that propagate along the interface between water and air under the predominating influence of gravity, and thus are often referred to as surface gravity waves. These surface gravity waves have their origin as wind waves, but are the consequence of dispersion of wind waves from distant weather systems, where wind blows for a duration of time over a fetch of water, and these waves move out from the source area at speeds that are a function of wave period and length. More generally, a swell consists of wind-generated waves that are not greatly affected by the local wind at that time. Swell waves often have a relatively long wavelength, as short wavelength waves carry less energy and dissipate faster, but this varies due to the size, strength, and duration of the weather system responsible for the swell and the size of the water body, and varies from event ...

Oki Islands
The is an archipelago in the Sea of Japan, the islands of which are administratively part of Oki District, Shimane Prefecture, Japan. The islands have a total area of . Only four of the around 180 islands are permanently inhabited. Much of the archipelago is within the borders of Daisen-Oki National Park. Due to their geological heritage, the Oki Islands were designated a UNESCO Global Geopark in September 2013. Geology The Oki Islands are volcanic in origin, and are the exposed eroded summits of two massive stratovolcanoes dating approximately 5 million years ago to the Tertiary and Quaternary periods. Dōgo to the east is the largest island in area, and has the highest elevation, Mount Daimanji, at above sea level. The Dōzen group of islands to the west are all portions of single ancient volcanic caldera which collapsed, leaving three large islands ( Nishinoshima, Nakanoshima and Chiburijima) and numerous smaller islands and rocks in a ring formation surrounding a cen ...

Honshu
, historically called , is the largest and most populous island of Japan. It is located south of Hokkaidō across the Tsugaru Strait, north of Shikoku across the Inland Sea, and northeast of Kyūshū across the Kanmon Straits. The island separates the Sea of Japan, which lies to its north and west, from the North Pacific Ocean to the south and east. It is the seventh-largest island in the world, and the second-most populous after the Indonesian island of Java. Honshu had a population of 104 million , constituting 81.3% of the entire population of Japan, and is mostly concentrated in the coastal areas and plains. Approximately 30% of the total population resides in the Greater Tokyo Area on the Kantō Plain. As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyōto, Nara and Kamakura. Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulleungdo
Ulleungdo (also spelled Ulreungdo; Hangul: , ) is a South Korean island 120 km (75 mi) east of the Korean Peninsula in the Sea of Japan, formerly known as the Dagelet Island or Argonaut Island in Europe. Volcanic in origin, the rocky steep-sided island is the top of a large stratovolcano which rises from the seafloor, reaching a maximum elevation of at Seonginbong Peak. The island is in length and in width; it has an area of . It has a population of 10,426 inhabitants.

The main city of Ulleung-do is the port of Dodong (), which serves as the main ferry port between Ulleung-do and the South Korean mainland. After tourism, the main economic activity is fishing, including its well-known harvest of squid, which can be seen drying in the sun in many places. History The island consists primarily of trachyandesite rock. A major explos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces.
