Changbai provides a natural laboratory for investigating the characteristics Received 12 November 2014 of volcanism and the dynamical evolution of the Northeast Asian continental margin. Mt. Changbai volcanoes Accepted 3 August 2015 predominantly consist of Wangtian'e volcano in China, Tianchi volcano spanning China and DPR Korea, and Available online 28 August 2015 Namphothe volcano in DPR Korea. Geochronology data and historical records of volcanism indicate that the three eruption centers were formed in the following sequence: Wangtian'e volcano to Namphothe and Tianchi Keywords: volcano, advancing temporally and spatially from southwest to northeast. The three eruption centers of Mt. China and Korea Re-eruption Changbai volcano are located close together, have similar magma evolution trends, bimodal volcanic rock distri- Mt.
