- VolcanoArshan volcano is a newly discovered active volcanic field in the central Da Hinggan Mountains of Inner Mongolia in NE China, 70 km from the border with Mongolia. The field contains more than 40 cinder cones, tephra layers and lava flows. The most recent volcanic eruptions occurred from the perfectly preserved 362 m high Yanshan cone and the 140 m deep Gaoshan crater. These vents produced basaltic lava flows to the northwest and formed natural dams blocking branches of the Halahahe river, creating 6 lakes.
