Two eruptions are known from Tianshan, in 50 AD (± 50 years) and 650 AD (± 50 years). The book, Aspects of Nature in Different Lands and Different Climates, Volume 1, reports that Pechan cone sent out streams of lava in the seventh century. The Chinese General, Teu-Hian (who was fleeing from the Chinese army) said that when climbing the Tianshan Mountains, saw "The Fire Mountains which send out masses of molten rock which flow for many Li"
