摘要
东北地区有4个活火山群,它们是长白山火山群、五大连池火山群、龙岗火山群和镜泊湖火山群。这些活火山群中的活火山有潜在的喷发危险,一旦再次爆发,由火山喷发空中降落堆积物、火山泥流、火山碎屑流、火山碎屑崩塌和熔岩流等造成的灾害和环境污染将是巨大的。当务之急是重塑火山喷发历史和模式,编制火山灾害预测图。东北地区火山灾害类型如此之多,影响范围如此之广,进行专项火山灾害调查研究是必须的。
There are four active volcano groups:Changbaishan volcano, Wudalianchi volcanic group, Longgang volcanic swarm and Jingpohu volcanic cluster in northeastern China. These active volcanoes are of potential dangers of eruption. Eruptions from active volcanoes in northeastern China can generate catastrophic hazards and cause environmental problems:pyroclastic falls, lahars, pyroclastic flows and avalanches of volcanic fragments. It is necessary to make a special survey of the volcanic hazards in northeastern China as it is an area highly vulnerable to volcanic hazards of various types. The most urgent task is to reconstruct the history and onodelling of volcanic eruption and compile maps for prediction of volcanic hazards.
