The Ulan Hada Volcano No 5 is covered with snow in Qahar Right Wing Rear Banner, Ulaanqab, North China’s Inner Mongolia autonomous region on Jan 13, 2018. The Ulan Hada Volcano Group, composed of more than 20 volcanoes, were formed approximately 10,000 years ago when the tremors of the Earth crust disturbed the subterranean tubular magma channels, causing the magma to sprout out, and then violently hurled it high up in the air, before gravity forced it down to Earth.
