Understanding of Historical Records about Volcanic Activities in Jeju Island, Korea

Historical records from the 15th to 19th centuries reveal that Jeju Island, Korea's most recent volcanic activity occurred in 1002 and 1007 AD, with no other documented eruptions. The study interprets these records volcanically, identifying a fissure eruption in 1002 and a potential underwater eruption in 1007, possibly linked to Hyeongpyeong Island or submerged volcanoes. Additionally, the term '瑞山' (Seosan) is reinterpreted as a metaphor for auspicious volcanic birth rather than a specific mountain name. Earthquakes and tsunamis in 1707–1708 were unrelated to local volcanism, instead correlating with Japan's Hoei earthquake. The research analyzes 25 historical texts, cautioning against inaccuracies due to transcription errors and author biases, particularly in non-official records.
