Identifying references to volcanic eruptions in Chinese historical records

Abstract In this study, we collect and translate observations and witness accounts suggestive of volcanic eruptions in ancient and modern China. The documents from the literature covered confirmed volcanic eruptions and suspected volcanic events. Recorded events concerning Tianchi ( c. 946 AD), Wudalianchi (1720, 1721) and Ashikule (1951) volcanoes relate to confirmed volcanic eruptions. Detailed records of Tianchi eruptions in historical documents span from 946 to 1903 AD. The real-time observations of the 1720–21 eruptions recorded by the government are presented. They describe a violent explosion and the development of lava flows at Laoheishan volcano. Evidence for events suggestive of volcanic activity are also presented for Dayingshan (1609, Tengchong), Man'anling (1883, Haikou), Chahayan (Heilongjiang), the South China Sea, Kui-shan Tao (late 1770s, Taiwan) and Penjia Islet (19 May 1916 and 29 June 1927, Taiwan). However, some supposed historical volcanic activities including Helanshan (Ningxia), Datong volcano, Rendagou (Sichuan) and Shizishan (Hunan) remain highly suspect according to their unclear positions and rough geological settings. These events may arise from the spontaneous combustion of coal. Records in Tianshan and Beiting Beishan (Xinjiang) may represent mud volcanoes. One case of an ancient Chinese Fengshui master interpreting geological processes from mythology is helpful when inspecting volcanology-related myths.
