Changbai Mountain is the largest volcanic area in East Asia. Changbai Mountain Tianchi volcano is the most complete Cenozoic multi-genesis compound volcano preserved in China, the cone is formed by the superposition of many volcanic magma ejections. It consists of five parts: Changbai Mountain giant volcanic cone, Wangtian’e shield volcanic cone, piedmont inclined lava plateau, lava platform and parasitic volcanic group. Changbai Mountain is an active volcano, which erupted many times in history, with an average of two or three hundred years in modern times.
Jingbo Lake volcano, Heilongjiang
Holocene volcano in Jingbo Lake, Heilongjiang Province, has 13 craters, all of which are composite volcanoes. It is speculated that the latest stage of Holocene volcanic activity in Jingbo Lake may be about 1000 years. According to the present evidence of volcanic geology and chronology, there is no objection to the Holocene volcanic eruption in Jingbo Lake.
Longgang volcano, Jilin
Longgang volcanic group is dotted with more than 160 volcanic cones, which show the characteristics of high density and multi-center explosive eruption. From the west of Jingyu county to the boundary between Jingyu and Huinan, the low-level volcano crater (maar) represented by Longwan, has become a major landscape of Longgang volcanic group, among them, Dalongwan and Triangle-longwan have been developed into the only scenic spots of the low-level volcanic crater with beautiful scenery in China. In the area surrounded by Longwan, a towering volcanic cone-Jinlong Dingzi volcano rises straight from the ground. Longgang volcano is one of the few Quaternary volcanoes that still have eruption activity in modern China.
