摘要
根据吉林省新生代以来火山喷溢活动的时空演化历史，特别是全新世以来火山活动频次与强度变化特征，以及现代喷发活动史记资料，结合１０多年火山动态观测数据，讨论了长白山天池火山潜在喷发的危险程度，认为其灾害性潜在喷发危险的时间尺度仍属于地质范畴。
According to the space-time evolutional histroy of volcanic eruption in Jilin Province since Cenozoic Era, especially the characteristics of frequency-strength change of volcanic activity since Holocene, the historical records of eruption, and the dynamic observational data over ten years, this paper discusses potential eruptive risk of Tianchi volcano, Changbaishan, and concludes that time-scale of its potential eruption risk still belongs to category of geologic age.
