Was just looking at North and South Korea because I picked up David
Halbersham’s The Coldest Winter: America and the Korean War today and saw this:
Massive Baitoushan stratovolcano, also known as Changbaishan and by the Korean names of Baegdu or P’aektu-san, is a relatively unknown, but volcanologically significant volcano straddling the China/Korea border.
A 5-km-wide, 850-m-deep summit caldera is filled by scenic Lake Tianchi (Sky Lake). A large Korean-speaking population resides near the volcano on both sides of the border. The 60-km-diameter dominantly trachytic and rhyolitic volcano was constructed over the Changbaishan (Laoheidingzi) shield volcano. Satellitic cinder cones are aligned along a NNE trend. One of the world’s largest known Holocene explosive eruptions took place from Baitoushan about 1000 AD, depositing rhyolitic and trachytic tephra as far away as northern Japan and forming in part the present caldera. Four historical eruptions have been recorded since the 15th century.
