Changbaishan
Paektu Mountain (), also known as Baekdu Mountain and in China as Changbai Mountain ( zh, s=长白山, t=長白山; Manchu: Golmin Šanggiyan Alin), is an active stratovolcano on the Chinese–North Korean border. At , it is the highest mountain of the Baekdudaegan and Changbai ranges. Koreans assign a mythical quality to the volcano and its caldera lake, considering it to be their country's spiritual home. It is the highest mountain in North Korea and Northeast China. A large crater lake, called Heaven Lake, is in the caldera atop the mountain. The caldera was formed by the VEI 7 "Millennium" or "Tianchi" eruption of 946, which erupted about of tephra. This was one of the largest and most violent eruptions in the last 5,000 years (alongside the Minoan eruption, the Hatepe eruption of Lake Taupō in around AD 180, the 1257 eruption of Mount Samalas near Mount Rinjani and the 1815 eruption of Tambora). The mountain plays an important mythological and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
946 Eruption Of Paektu Mountain
The 946 eruption of Paektu Mountain in Korea and China, also known as the Millennium Eruption or Tianchi eruption, was one of the most powerful volcanic eruptions in recorded history and is classified as a VEI-7 event. The eruption resulted in a brief period of significant climate change in Manchuria. The year of the eruption has not been precisely determined, but a possible year is A.D. 946. The eruption ejected about of tephra and collapsed the mountain into a caldera, which now contains the crater lake named Heaven Lake. The eruption began with a strong Plinian column, and ended with voluminous pyroclastic flows. An average of of Plinian ashfall and co–ignimbrite ashfall covered about of the Sea of Japan and northern Japan. This ash layer has been named the "Baegdusan-Tomakomai ash" (B-Tm). It probably occurred in winter in late A.D. 946. This was one of the largest and most violent eruptions in the last 5,000 years, along with the Minoan eruption of Thera, the Hatepe e ...

Jilin
Jilin (; alternately romanized as Kirin or Chilin) is one of the three provinces of Northeast China. Its capital and largest city is Changchun. Jilin borders North Korea (Rasŏn, North Hamgyong, Ryanggang and Chagang) and Russia (Primorsky Krai) to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west. Along with the rest of Northeast China, Jilin underwent an early period of industrialization. However, Jilin's economy, characterized by heavy industry, has been facing economic difficulties with privatization. This prompted the central government to undertake a campaign called "Revitalize the Northeast". The region contains large deposits of oil shale. Name The name "Jilin" originates from ''girin ula'' () , a Manchu phrase meaning "along the river", shortened to Kirin in English. This Manchu term was transcribed into ''jilin wula'' ( t , s ) in Chinese characters and shortened the first two characters, which are tran ...

1257 Samalas Eruption
In 1257, a catastrophic eruption occurred at the Samalas volcano on the Indonesian island of Lombok. The event had a probable Volcanic Explosivity Index of 7, making it one of the largest volcanic eruptions during the current Holocene epoch. It left behind a large caldera that contains Lake Segara Anak. Later volcanic activity created more volcanic centres in the caldera, including the Barujari cone, which remains active. The event created eruption columns reaching tens of kilometres into the atmosphere and pyroclastic flows that buried much of Lombok and crossed the sea to reach the neighbouring island of Sumbawa. The flows destroyed human habitations, including the city of Pamatan, which was the capital of a kingdom on Lombok. Ash from the eruption fell as far as away in Java; the volcano deposited more than of rocks and ash. The aerosols injected into the atmosphere reduced the solar radiation reaching the Earth's surface, causing a volcanic winter and cooling the atmospher ...

Mount Rinjani
Mount Rinjani ( id, Gunung Rinjani) is an active volcano in Indonesia on the island of Lombok. Administratively the mountain is in the Regency of North Lombok, West Nusa Tenggara (Indonesian: ''Nusa Tenggara Barat'', NTB). It rises to , making it the second highest volcano in Indonesia. It is also the highest point in the Indonesian province of West Nusa Tenggara. Adjacent to the volcano is a caldera, which is filled partially by the crater lake known as Segara Anak or Anak Laut (''Child of the Sea''), due to the color of its water, as blue as the sea (''laut''). This lake is approximately above sea level and estimated to be about deep; the caldera also contains hot springs. Sasak tribe and Hindu people assume the lake and the mount are sacred and some religious activities are occasionally done in the two areas. UNESCO made Mount Rinjani Caldera a part of the Global Geoparks Network in April 2018. Geography Lombok is one of the Lesser Sunda Islands, a small archipelago ...

Northeast China
Northeast China or Northeastern China () is a geographical region of China, which is often referred to as "Manchuria" or "Inner Manchuria" by surrounding countries and the West. It usually corresponds specifically to the three provinces east of the Greater Khingan Range, namely Liaoning, Jilin, and Heilongjiang, but historically is meant to also encompass the four easternmost prefectures of Inner Mongolia west of the Greater Khingan. The heartland of the region is the Northeast China Plain, the largest plain in China, with an area over . It is separated from Russian Far East to the north by the Amur, Argun, and Ussuri rivers; from Korea to the south by the Yalu and Tumen Rivers; and from Inner Mongolia to the west by the Greater Khingan and parts of the Xiliao River. Due to the shrinking of its once-powerful industrial sector and decline of its economic growth and population, the region is often referred to as China's Rust Belt. As a result, a campaign named Northeast Area Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1815 Eruption Of Mount Tambora
Mount Tambora is a volcano on the island of Sumbawa in present-day Indonesia, then part of the Dutch East Indies, and its 1815 eruption was the most powerful volcanic eruption in recorded human history. This volcanic explosivity index (VEI) 7 eruption ejected of material into the atmosphere, and was the most recent confirmed VEI-7 eruption. Although the Mount Tambora eruption reached a violent climax on 10 April 1815, increased steaming and small phreatic eruptions occurred during the next six months to three years. The ash from the eruption column dispersed around the world and lowered global temperatures in an event sometimes known as the Year Without a Summer in 1816. This brief period of significant climate change triggered extreme weather and harvest failures in many areas around the world. Several climate forcings coincided and interacted in a systematic manner that has not been observed after any other large volcanic eruption since the early Stone Age. Chronology of th ...

Minoan Eruption
The Minoan eruption was a catastrophic Types of volcanic eruptions, volcanic eruption that devastated the Aegean Islands, Aegean island of Thera (also called Santorini) circa 1600 BCE. It destroyed the Minoan civilization, Minoan settlement at Akrotiri (prehistoric city), Akrotiri, as well as communities and agricultural areas on nearby islands and the coast of Crete with subsequent earthquakes and tsunamis. With a Volcanic Explosivity Index, VEI magnitude between 6 and 7, resulting in an ejection of approximately of dense-rock equivalent (DRE), the eruption was List of known large volcanic eruptions, one of the largest volcanic events on Earth in human history. Since tephra from the Minoan eruption serves as a marker horizon in nearly all archaeological sites in the Eastern Mediterranean, its precise date is of high importance and has been fiercely debated among archaeologists and volcanologists for decades, without coming to a definite conclusion.

Tephra
Tephra is fragmental material produced by a 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. Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. 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. 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 fossil and its place within the geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
