摘要
中国东北晚全新世火山活动十分强烈,1200AD±的一次活跃期及其所产生的地质灾害已被很好地研究.根据历史记载、热释光测年和14C测年等资料,在1720AD±存在最新的一次活跃期.确证这一活跃期的存在并开展火山地质灾害调查与研究,对探索火山活动节律和火山地质灾害预警等均有重要的理论和实际意义.
The Late Holocene volcanic activities in Northeast China are severely intense. The volcanic active stage m 1200 AD± has been well studied by previous geologists. Based on historical documents, thermoluminescence dating and isotopic age of ^14C, as well as the newest achievements by geological survey, the latest volcanic active stage around 1720 AD in Late Holocene Epoch is confirmed. Study on such volcanic active stage is importantly significant to the exploration of the rhythms of volcanic activities and early warning of geologic hazards.
