BackgroundGabillema is a rhyolitic stratovolcano along the axis of the Addado graben. The volcano was constructed at the intersection of the central Afar rift zone with the northern end of the NE-SW-trending Ethiopian rift. Rhyolitic lava domes are located on the flanks of the volcano, and a 5 x 17 km basaltic lava field that covers the Ado Bad plain north of the volcano originated from a broad area of fissure vents and spatter cones on the north side of Gabillema volcano. Young lava flows also occur south and east of the volcano, the latter along E-W-trending fissures. This period of rejuvenation, perhaps not directly related to Gabillema, has included rhyolitic as well as basaltic volcanism. For the Ethiopian rift south of 11 degrees north, official names from the new Ethiopian Geological Survey's 1:250,000 topo maps have replaced earlier names published in the geological literature.
