Paektu Mountain, also known as Changbaishan, on the border of the Democratic People's Republic of Korea and China[1] erupted in late 946 CE.[2][3] This event is known as the Millennium Eruption or Tianchi eruption[4] and it was one of the most powerful volcanic eruptions in recorded history and is classified as a Magnitude 6.5-7 (or VEI-6) eruption.[5][6][7]
The eruption ejected about 13–47 cubic kilometres[5][6][7] 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.[8] 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.[9][10] This ash layer has been named the "Baegdusan-Tomakomai ash" (B-Tm)[9] 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 most powerful eruptions in the last 5,000 years, along with the Minoan eruption of Thera, the Hatepe eruption of Lake Taupō (around 230 CE), the 431 CE eruption of Lake Ilopango, 1257 eruption of Mount Samalas near Mount Rinjani, and the 1815 eruption of Mount Tambora.
