This study re-assesses the historical records pertaining to the activity of Mt. Baekdu according to volcanic phenomena. We categorized volcanic phenomena into five categories: rumbling, atmospheric abnormality, ash rain, ash cloud and phenomenon sightings, and investigated historical records (in Chinese) for each phenomenon and identified their volcanological implications. Among the volcanic phenomena, ash rain had the most abundant records, and in particular, Goryeosa recorded the ash rain phenomenon 56 times. And more than 90 volcanic eruptions were discovered from the Millennium Eruption from November 3, 946 AD, to February 7, 947 AD, most of which were either Plinian or Vulcanian eruptions with volcanic ash dispersed into the regions surrounding the volcano creating fallout ash. Based on the historical eruptions, eruption precursors, and volcanic unrest of the volcano between 2002 and 2006, Mt. Baekdu is regarded as an active volcano that has the potential to erupt. Therefore, to mitigate the hazard caused by the eruption of Mt. Baekdu, it is necessary to analyze the historical eruption records of Mt. Baekdu and understand the characteristics of the eruptions through this analysis.

白头山（白头山、天池）火山活动历史记录的重新评估

本研究根据火山现象重新评估有关白头山活动的历史记录。我们将火山现象分为五类：轰鸣声、大气异常、火山灰雨、火山灰云和现象目击事件，并对每种现象的历史记录进行了调查，并确定了它们的火山学含义。火山现象中，火山灰雨的记录最为丰富，特别是高丽山，记录了火山灰雨现象56次。从公元946年11月3日到公元947年2月7日的千年喷发中，发现了90多起火山喷发，其中大多数是普林尼式或武尔坎式喷发，火山灰散布到火山周围区域，形成沉降灰。根据历史喷发、喷发前兆，以及2002年至2006年间的火山动荡，白头山被视为一座有喷发潜力的活火山。因此，为了减轻白头山喷发造成的危害，有必要对白头山历史喷发记录进行分析，通过分析了解白头山喷发的特征。
