The Chosun Ilbo is reporting that Mt Paektusan (also spelled as Baekdusan and known in China as Changbaishan), the iconic volcano that forms the apex of the North Korea-China border, is "99% likely to erupt by 2032":
Taniguchi based his inference on the historical relationship in timing between earthquakes in Japan and eruptions of Mt. Baekdu. Historical documents from Korea and China show that Mt. Baekdu erupted at least six times between the 14th and 20th centuries, Taniguchi said, and every time it followed an earthquake in Japan.
The water stored in the Lake of Heaven bursting out, sweeping across North Korea’s Hamgyŏng Province and beyond. Researchers at the National Institute of Environmental Research say that we should expect sediment to pile up from a few meters deep to hundreds of meters.
The area is surrounded by black pumice, which results when basaltic magma was forcibly ejected. It’s frequently found in areas of past volcanic eruptions. The layer of pumice found around Paektusan is as much as seventy-five meters thick. It drops to ten meters elsewhere in Hamgyŏng Province, only ten centimeters in the East Sea, and five centimeters near the island of Hokkaidō in Japan.
