North Korean volcano with molten rocks threatens to explode at any moment

North Korean volcano Mount Paektu has substantial molten underside, increasing the possibility that it will burst at any point. The eruption occurred around one thousand years ago, which is roughly 946 A.M. Mount Paektu (also known as Changbaishan) erupted with such a force that it was able to send crackling rock all the way from Japan. A team of international scientists, including those from North Korea and China as well as the United States and Britain, conducted extensive research on the volcanic’s bottom. They published their results in Scientific Advances (citation above). James Hammond (Department of Earth and Planetary Sciences Birkbeck College University of London) is a co-author. He and his colleagues believe that their findings and research have helped us understand the inner structure of the mysterious volcano. It lies at the border of North Korea and China. Heaven Lake is a crater lake in a caldera at the top of Mount Paektu. This volcano forms part the Baekdudaegan and Changbai mountain ranges. It can be found in North Korea, northeastern China and partly in North Korea. Image: Wikipedia. Dr. Hammond and scientists from North Korea’s Earthquake Administration, University of Cambridge’s Department of Geography and China’s Environmental Education Media Project, as well as the US Geological Survey and Pyongyang International Centre of Technology and Economics in North Korea have taken seismic images beneath Mount Paektu’s crust. Massive amount of partial melt Scientists presented seismic data which revealed large areas of rock, molten rocks and crystals. This is called partial melt. The partial melt could be responsible for an increase in seismic activity and the emission of volcanic gasses during the first years of the century. It also holds the key to the mystery of why Mount. Paektu’s eruption was so powerful around one thousand years ago. The magma that was stored beneath the volcano and its composition, as well as the crust thickness, were not known. The researchers used ultrasensitive and state-of the-art technology to detect earthquakes. This is the first use of such technology in North Korea. They have also shown that volcanism has altered the Earth’s crust in this area over the past 3.5 million years. Locations of stations. Red circles indicate the locations of seismic stations that were used for the receiver function study. North Korean stations include Jang Gun Peak, Jangtu Bridge (PDBD), Mudu Peak(MDPD), Sin Mu Song (SMSD), Paek San Ri (PSRD) and Sing Hung Ri (SHRvD). Image: Science Advances. The extent of partial melting is at most 20 kilometers (12.4 mi wide. However, its precise volume and scale are still not known. Dr Hammond stated that volcanic eruptions (especially those occurring from large volcanoes like Mt. Paektu can cause significant damage to their surroundings. Our vulnerability to volcanic hazards has increased with globalization and development. We must pay attention to understanding volcanic hazards, regardless of where they may be.” Our data show that significant amounts of molten rock are found in the crust below Mt. Paektu. Paektu. The authors stated in an abstract that the region of melt could be a source of magmas, which may have been caused by an episode of volcanic instability between 2002, and 2005.” A thousand years ago Mt. Paektu was so violently erupted that the cracked rock reached as far as Hokkaido, Japan. Image: It began in 2011 After a trip to Pyongyang, North Korea’s capital. Paektu, 2011, The international scientific team has been working with many organizations and the Richard Lounsbery Foundation to conduct field-based geophysical and volcanological studies along the North Korean border. The University of Cambridge’s Department of Geography says that there is evidence for partial melt beneath Mount.
