Dabbahu Volcano (also Boina, Boyna or Moina) is an active volcano located in the remote Afar Region of Ethiopia. This stratovolcano[2] is part of the Afar Triangle (Afar Depression), a highly active volcanic region which includes Erta Ale.[1] An eruption on September 26, 2005 created a large fissure in the ground, known as the Dabbahu fissure.[3]

2005 eruption


The only eruption of the volcano in recorded history occurred on September 26, 2005. Preceding the eruption, the ground swelled and an earthquake swarm consisting of over 130 events occurred.[2] Earthquakes measured 4.2 on the Richter scale.[4] The eruption began 5 kilometers northeast of the summit. Ash from the eruption darkened the area surrounding the volcano for nearly 3 days.

The eruption formed a 500 m long fissure and a 30 m (98 ft) wide pumice cone at the fissure's southern end. Ash reached as far as the administrative center of Teru, located 40 km (25 mi) southwest of the volcano.


Plate tectonics


The volcano is located along the Somali Plate. Researchers predict that the land along this region, known as the East African Rift, will eventually break away, creating a new island consisting of eastern Ethiopia and Djibouti with a new sea in between.[5][6] Using seismic data from 2005, a research study predicted that this new ocean would likely be formed in about one million years.[7]


Life


Scientists are studying the fissure for extremophiles.[8]

[ru] Даббаху

Даббаху — вулкан, расположенный в пустыне Данакиль в удалённом районе Афар в Эфиопии. Вулкан Дабаху представляет собой составную часть так называемого «афарского треугольника» — зоны сильной вулканической активности, включающей вулкан Эртале. Извержение 2005 года привело к образованию большой трещины земной коры, известной как «разлом Даббаху». Вулкан считается самым горячим местом на поверхности Земли.[2]
