Changbaishan eruption 946 AD

The Changbaishan eruption, one of the most violent of the last two millennnia, has been dated to within three months of the winter of 946 AD

The fossilised remains of a tree killed more than 1,000 years ago when a volcano blew a four-kilometre-wide hole in the landscape, on the border between China and North Korea, have helped an international team of scientists date one of the most violent eruptions of the last two millennnia to within three months of the winter of 946 AD.
The date matches a vivid description in a chronicle from a temple in Japan, far from any of that country's active volcanoes, and 1,000 kilometres from the Changbaishan volcano.

UK Team Unlocking Secrets of North Korea Volcano

Fresh off their third visit to the volcano, two British scientists studying the mountain in an unprecedented joint project with North Korea say they may soon be able to reveal some secrets of the volcano, including its likelihood of erupting again. They're collecting seismic data and studying rocks ejected in Paektu's "millennium eruption" sometime in the 10th century.

Volcanic sleeping giant opens North Korean co-operation

Scientists from the UK, US and North Korea have joined forces to monitor the volcano responsible for one of the largest eruptions in history.
The volcano straddles the border between North Korea and China, and has been largely dormant since erupting a little over a thousand years ago.
Despite being at the top of the list of big eruptions, Mount Paektu remains obscure and enigmatic.
Details of the collaborative effort have been outlined in Science journal.

Chinese volcano approved as national geological park

A mountain in northeast China that is home to the world's highest volcanic lake has been approved as a national geological park, sources with the mountain management committee said on Friday.
Mount Changbai, located on the border of China and the Democratic People's Republic of Korea (DPRK), has been officially named the Jilin Changbai National Volcanic Geological Park by the Ministry of Land and Resources, according to the sources.

Title: Recent unrest of Changbaishan volcano, northeast China: A precursor of a future eruption? 
Authors: Jiandong Xu, Guoming Liu, Jianping Wu, Yuehong Ming, Qingliang Wang, Duxin Cui, Zhiguan Shangguan, Bo Pan, Xudong Lin, Junqing Liu 

Over 12 years of continuous monitoring of Changbaishan volcano in the border region of China and North Korea by means of volcanic seismicity, ground deformation, and volcanic gas geochemistry yields new evidence for magmatic unrest of the volcano between 2002 and 2006. In this so-called "active period," the frequency of volcanic earthquakes increased by about 2 orders of magnitude compared to that of the background "inactive periods." The active period was also accompanied by ground inflation, high values of CO2, He, H2, and high ratios of N2/O2 and 3He/4He in volcanic gases released from three hot springs near the caldera rim. The monitoring evidence implies pressurisation of the magma chamber, possibly caused by incremental magma recharge. The ground deformation data from both GPS and precise levelling are modelled to suggest the corresponding deformation source is at 2-60 km depth beneath the volcano's summit, where earthquake swarms were detected in 2002 and 2003. Our findings suggest that the magma chamber beneath Changbaishan volcano has awakened and resumed activity after remaining dormant since AD 1903. There is an urgent need to keep close watch on this active and very hazardous volcano in northeast China.

North Korea, apparently spooked by the earthquake in Japan, has proposed conducting research with rival South Korea on volcanic activity at their highest mountain, considered sacred by the North.
North Korea's earthquake bureau sent a letter to South Korea's weather agency on Thursday proposing joint quake and volcano research "in the common interests of the nation" at Mount Paektu, the state-run Korean Central News Agency reported.

The Tianchi volcano located in Changbai mountain along China's border with the Democratic People's Republic of Korea (DPRK) will not erupt in the next dozens years, a Chinese seismology expert said Friday.
The comprehensive monitor data showed the volcano was in a stable condition without any abnormity, said Yang Qingfu, director of earthquake and volcano analysis and forecast centre with the seismology bureau of northeast China's Jilin Province.

The 969±20 CE Plinian eruption of Baitoushan Volcano (China/North Korea) produced a total tephra volume of 96±19 km³ [magma volume (DRE): 24±5 km³
Lake Tianchi fills the 5 km wide caldera. There were possible gas emissions at Baitoushan Volcano in 1994. The eruption of Baitoushan volcano in 1054 was one of the largest eruptions in the world in the past 10,000 years.

Changbai volcano, also called Tianchi or Baitoushan volcano, is located in the Changbai Mountains, close to the boundary between NE China and North Korea (Figure 1a). Changbai volcano erupted in BC 1120, AD 1050, 1413, 1597, 1668, and 1702 (Simkin & Siebert, 1994; Liu, 2000). However, the origin of such intraplate volcanoes is still unclear.

Major eruption of Mt. Baekdu 'possible'

The government is paying attention to the possibility of a major eruption of Mt. Baekdu, the 2,744-meter dormant volcano on the border between North Korea and China, which experts here and in China claim has shown signs of becoming active.

Mountain Baekdu, a dormant volcano on the border between North Korea and China, is showing signs of a possible eruption in the near future, experts warned Tuesday.
According to historical records, Baekdu was an active volcano. Major activity in the 1960s created a caldera on its peak, whose circumference is nearly 14 kilometres with an average depth of 213 metres and maximum of 384 metres.
