Located in the Danakil Depression (or Afar Depression) in the Afar Region of northeastern Ethiopia, Erta Ale is one of the driest, lowest, and hottest places on Earth. Erta Ale means “smoking mountain” in the local Afar language and its southernmost pit is known locally as “the gateway to Hell“. Many media has named it in different ways, trying to express it’s magical being.
Erta Ale is 613 metres (2,011 ft) high, with one or sometimes two active lava lakes at the summit which occasionally overflow on the south side of the volcano. It is notable for holding the longest-existing lava lake, present since the early years of the twentieth century (1906). Volcanoes with lava lakes are very rare: there are only six in the world.
Erta Ale is centered over the East African Rift system, which is a triple junction setting whose movements are resulting in the formation of a pull-apart basin or rift. The volcano comprises mainly Mafic material which has been brought up to the surface caused by unroofing of the mantle due to this rift formation.
Known by the Afar as the “smoking mountain” and “the gateway to hell,” Erta Ale is a 2,011-foot-high constantly active basaltic shield volcano. It is one of only a handful of continuously active volcanos in the world, and a member of an even more exclusive group: volcanos with lava lakes. While there are only five known volcanos with lava lakes globally, Erta Ale often has two active lava lakes, making it a unique site.
