东北大陆地区的浅源地震、深源地震以及火山活动等汇集一起,不仅在我国,就是在世界上也很罕见.综合研究已有资料,清楚地表明东北地区晚新生代以来处于引张地裂运动环境,受到西太平洋构造带内带弧后扩张和青藏—蒙古高原隆起东缘双重地裂运动影响.从这个角度深入研究东北地区的浅源地震、深源地震、火山活动、以及其他相关地质灾害的成因.揭示它们的内在联系与活动规律,对地震、火山、甚至其他地质灾害的预测和预报都将发挥积极的促进作用.
Together with the shallow earthquakes in the northeast China, deep-seated earthquakes and volcanic activities, it is not only rare in our country, but also in the world. Comprehensive research has been made on the data that clearly shows that the northeastern region has been undergoing earth- The movement environment is affected by the double post-arc extension in the western Pacific tectonic belt and the double-cleavage movement along the eastern margin of the Qinghai-Tibet Plateau uplift from this point of view.From this point of view, deep-sourced earthquakes, deep-seated earthquakes, volcanic activities and other related geology The causes of disasters, revealing their internal relations and the law of activity, will play an active role in promoting the prediction and prediction of earthquakes, volcanoes and even other geological disasters.
