Monte Paektu

Changbaishan

Estratovolcán · China-North Korea · 2744 m

Lake Tianchi occupies the 5-km-wide, 850-m-deep summit caldera of Changbaishan, which straddles the China/Korea border. The volcano is also known as Baitoushan and by the Korean names of Baegdu or P'aektu-san. This view looks from the northern rim on the Chinese side towards the SE caldera wall on the Korean side. One of the world's largest known Holocene explosive eruptions took place from Changbaishan about 1000 CE, depositing tephra as far away as northern Japan.

Resumen geológico

Massive Changbaishan stratovolcano (also known as Baitoushan and by the Korean names of Baegdu, Paektu, or P'aektu-san), is located along the China/Korea border. A 5-km-wide, 850-m-deep summit caldera is filled by Lake Tianchi (Sky Lake). 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 largest known Holocene explosive eruptions took place here about 946 CE, depositing tephra as far away as northern Japan and forming in part the present caldera; Yang et al. (2021) estimated the total erupted volume to be 40-98 km3. Minor eruptions have been recorded since the 15th century.

Resumen de Wikipedia

Resumen en inglés

The Changbai Mountains are a major mountain range in East Asia that extends from the Northeast Chinese provinces of Heilongjiang, Jilin and Liaoning, across the China-North Korea border, to the North Korean provinces of Ryanggang and Chagang. They are also referred to as the Šanggiyan Mountains in the Manchu language, or the Great Paekdu in Korean. Most of its peaks exceed 2,000 m (6,600 ft) in height, with the tallest summit being Paektu Mountain at 2,744 m (9,003 ft), which contains the Heaven Lake, a large volcanic crater lake at a surface elevation of 2,189.1 m (7,182 ft). The protected area Longwanqun National Forest Park is located within the vicinity of the mountain range.
