Baekdu Mountain
Paektu Mountain or Baekdu Mountain () is an active stratovolcano on the Chinese–North Korean border. In China, it is known as Changbai Mountain (). At , it is the tallest mountain in North Korea and Northeast China and the tallest mountain of the Baekdu-daegan and Changbai mountain ranges. The highest peak, called Janggun Peak, belongs to North Korea. The mountain notably has a caldera that contains a large crater lake called Heaven Lake, and is also the source of the Songhua, Tumen, and Yalu rivers. Korean and Manchu people assign a mythical quality to the mountain and its lake, and consider the mountain to be their ancestral homeland. The mountain's caldera was formed by an eruption in 946 that released about of tephra. The eruption was among the largest and most powerful eruptions on Earth in the last 5,000 years. The volcano last erupted in 1903, and is expected to erupt around every hundred years. In the 2010s, concerns over an upcoming eruption prompted several ...

Korea
Korea is a peninsular region in East Asia consisting of the Korean Peninsula, Jeju Island, and smaller islands. Since the end of World War II in 1945, it has been politically Division of Korea, divided at or near the 38th parallel north, 38th parallel between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK). Both countries proclaimed independence in 1948, and the two countries fought the Korean War from 1950 to 1953. The region is bordered by China to the north and Russia to the northeast, across the Yalu River, Amnok (Yalu) and Tumen River, Duman (Tumen) rivers, and is separated from Japan to the southeast by the Korea Strait. Known human habitation of the Korean peninsula dates to 40,000 BC. The kingdom of Gojoseon, which according to tradition was founded in 2333 BC, fell to the Han dynasty in 108 BC. It was followed by the Three Kingdoms of Korea, Three Kingdoms period, in which Korea was divided into Goguryeo, Baekje, a ...

Baekdu-daegan
Baekdu-daegan () is a traditional Korean conception of the mountains and consequently the watersheds of the Korean Peninsula. The mountain range stretches the length of the Korean Peninsula, around 1,500 km, from Baekdu Mountain in the north to Jirisan, or Hallasan on Jeju Island in the south. The mountain range is often associated with national identity and traditional Korean shamanism. Baekdu-daegan is considered to include the Sobaek and Taebaek mountain ranges. Although currently impossible due to the Korean Demilitarized Zone between North Korea and South Korea, hiking the length of the mountains is considered a desirable goal aligned with the Korean reunification movement. The South Korean portion of the range is popular for hiking. It is often referred to as the "spine" or "backbone" of the Korean Peninsula. Description Baekdu-daegan describes a 1,500 km long mountain range that runs from Paektu Mountain in the north to Cheonwangbong Peak of Jirisan in t ...

Book Of Wei
The ''Book of Wei'', also known by its Chinese name as the ''Wei Shu'', is a classic Chinese historical text compiled by Wei Shou from 551 to 554, and is an important text describing the history of the Northern Wei and Eastern Wei from 386 to 550. Widely regarded as the official and authoritative source historical text for that period, it is one of the Twenty-Four Histories. Origin and reception The Northern Wei dynasty was established in 386 by the Tuoba clan. The greatest accomplishment of the Northern Wei dynasty was the unification of Northern China in 439. An internal struggle resulted in a split which introduced the Eastern Wei and the Western Wei. The Eastern Wei dynasty was short-lived. Established in 534, several military campaigns were fought to try and reunite east and west but each failed. In 550, the area was taken over by Gao Yang who founded his own dynasty which he names the Northern Qi. It is the history of these two dynasties that Wei Shou attempted to r ...

Book Of The Later Han
The ''Book of the Later Han'', also known as the ''History of the Later Han'' and by its Chinese name ''Hou Hanshu'' (), is one of the Twenty-Four Histories and covers the history of the Han dynasty from 6 to 189 CE, a period known as the Later or Eastern Han. The book was compiled by Fan Ye and others in the 5th century during the Liu Song dynasty, using a number of earlier histories and documents as sources. Background In 23 CE, Han dynasty official Wang Mang was overthrown by a peasants' revolt known as the Red Eyebrows. His fall separates the Early (or Western) Han dynasty from the Later (or Eastern) Han dynasty. As an orthodox history, the book is unusual in being completed over two hundred years after the fall of the dynasty. Fan Ye's primary source was the '' Dongguan Hanji'' (東觀漢記; "Han Records of the Eastern Lodge"), which was written during the Han dynasty itself.

Classic Of Mountains And Seas
The ''Classic of Mountains and Seas'', also known as ''Shanhai jing'' (), formerly romanized as the ''Shan-hai Ching'', is a Chinese classic text and a compilation of mythic geography and beasts. Early versions of the text may have existed since the 4th century BCE, but the present form was not reached until the early Han dynasty. It is largely a fabulous geographical and cultural account of pre- Qin China as well as a collection of Chinese mythology. The book is divided into eighteen sections; it describes over 550 mountains and 300 channels. Authorship Since Sima Qian, the debate about the author(s) of the book has been going on for more than two thousand years. Definite references Yu the Great and Boyi The earliest records of the ''Classic of Mountains and Seas'' can be found in Sima Qian's "Records of the Grand Historian - Biography of Dawan". The author of the book was first clearly identified in "The table of the Classic Mountains and Seas" written by Liu Xiu in ...

Qing Dynasty
The Qing dynasty ( ), officially the Great Qing, was a Manchu-led Dynasties of China, imperial dynasty of China and an early modern empire in East Asia. The last imperial dynasty in Chinese history, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China (1912–1949), Republic of China. At its height of power, the empire stretched from the Sea of Japan in the east to the Pamir Mountains in the west, and from the Mongolian Plateau in the north to the South China Sea in the south. Originally emerging from the Later Jin (1616–1636), Later Jin dynasty founded in 1616 and proclaimed in Shenyang in 1636, the dynasty seized control of the Ming capital Beijing and North China in 1644, traditionally considered the start of the dynasty's rule. The dynasty lasted until the Xinhai Revolution of October 1911 led to the abdication of the last emperor in February 1912.

Manchu People
The Manchus (; ) are a Tungusic peoples, Tungusic East Asian people, East Asian ethnic group native to Manchuria in Northeast Asia. They are an officially recognized Ethnic minorities in China, ethnic minority in China and the people from whom Manchuria derives its name. The Later Jin (1616–1636), Later Jin (1616–1636) and Qing dynasty, Qing (1636–1912) dynasties of China were established and ruled by the Manchus, who are descended from the Jurchen people who earlier established the Jin dynasty (1115–1234), Jin dynasty (1115–1234) in northern China. Manchus form the largest branch of the Tungusic peoples and are distributed throughout China, forming the fourth largest ethnic group in the country. They are found in 31 Chinese provincial regions. Among them, Liaoning has the largest population and Hebei, Heilongjiang, Jilin, Inner Mongolia and Beijing have over 100,000 Manchu residents.

Emblem Of North Korea
The National Emblem of the Democratic People's Republic of Korea is one of the national symbols of North Korea. Prominent features on the emblem are a red star, a hydroelectric plant (the Sup'ung Dam) and Mount Paektu. The design bears similarities to the emblem of the Soviet Union and other emblems done in the socialist heraldic style. The emblem was designed by Kim Chu-gyŏng, a painter and a principal of the Pyongyang Art College who also designed the national flag. Description The emblem features the Sup'ung Dam under Mount Paektu and a power line as the escutcheon. The crest is a five-pointed shining red star. It is supported with ears of rice, bound with a red ribbon bearing the inscription "The Democratic People's Republic of Korea" in Chosŏn'gŭl characters. While the design of the hydroelectric plant is generic in appearance, its identity is given away by the fact that Sup'ung was the only power station of its kind at the time when the emblem was designe ...

Tephra
Tephra is fragmental material produced by a Volcano, volcanic eruption regardless of composition, fragment size, or emplacement mechanism. Volcanologists also refer to airborne fragments as pyroclasts. Once clasts have fallen to the ground, they remain as tephra unless hot enough to fuse into pyroclastic rock or tuff. When a volcano explodes, it releases a variety of tephra including ash, cinders, and blocks. These layers settle on the land and, over time, sedimentation occurs incorporating these tephra layers into the geologic record. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which Paleoecology, paleoenvironmental or Archaeology, archaeological records can be placed. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer. These fossils are later dated by scientists to determine the age of the ...

946 Eruption Of Paektu Mountain
The 946 eruption of Paektu Mountain, a stratovolcano on the border of North Korea and China also known as Changbaishan, occurred in late 946 CE. This event is known as the Millennium Eruption or Tianchi eruption. It is one of the most powerful volcanic eruptions in recorded history; classified at least a VEI 6. The eruption ejected about 13–47 cubic kilometres of magma (dense rock equivalent) and formed a caldera, which now contains a lake (Heaven Lake). The eruption had two phases that each included a Plinian fallout and a pyroclastic flow and erupted magmas that were different in composition. An average of 5 cm (2.0 in) of Plinian ashfall and co–ignimbrite ashfall covered about 1,500,000 km2 (580,000 sq mi) of the Sea of Japan and northern Japan. This ash layer has been named the "Baegdusan-Tomakomai ash" (B-Tm) and is valuable marker horizon for correlating regional sedimentary archives in and around the Sea of Japan. The Millennium Eruption was one of the largest and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yalu River
The Yalu River () or Amnok River () is a river on the border between China and North Korea. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between China and North Korea. Its valley has been the scene of several military conflicts in the past centuries. It borders North Korea to the south and China to the north. Name The Chinese name ''Yalu'' ("duck-green") was first attested during the Tang dynasty. According to the '' Tongdian'' (8th century), the river was named after its color, which resembled that of a mallard's head. The Korean name "Amnok" follows the Sino-Korean reading of the same name. In ancient times, the river was known as ''Peishui'' (''Paesu'', 浿水) or ''Mazishui'' (''Majasu'', 馬訾水). Historically, it was also known by the Korean name of ''Arinarye'' (아리나례강, 阿利那禮江). ''Ari'', a word from Old Korean used to refer to the 'spirituality (신령성; 神靈性) of the sun'. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
