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
[edit | edit source]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 (1,600 ft) fissure (Lua error: callParserFunction: function "#coordinates" was not found.) 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
[edit | edit source]
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 could occur in about one million years.[7]
Life
[edit | edit source]Scientists are studying the fissure for extremophiles.[8]
