BackgroundDabbahu, also known as Boina, Boyna, or Moina, is a Holocene volcanic massif forming an axial range of the Afar depression SSW of the Alayta massif. Pantelleritic obsidian flows, lava domes, and pumice cones form the summit and upper flanks of the volcano, which rises above the Teru Plain and was built over a base of basaltic-to-trachytic lava flows of a shield volcano. Late-stage basaltic fissure eruptions occurred at the NW base of the volcano. Abundant fumaroles are located along the crest of the volcano and extend NE towards Alayta volcano. The first historical eruption of Dabbahu took place from a fissure vent on the NE flank of the volcano in September 2005 and produced ashfall deposits and a small pumice dome. More than 6000 persons were evacuated from neighboring villages.
