Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Alu-Dalafilla
The steep-sided, conical Dalafilla volcano rises 300 m above surrounding lava fields of Alu volcano in the foreground in this view from the NW. This morphology, unusual for the Erta Ale Range volcanoes, results from the extrusion of viscous, silicic lava flows. These silicic flows extend primarily to the east from the 613-m-high summit. On the western side they are blocked by walls of a horst structure along the crest of the Erta Ale Range that forms the linear ridge in the right side of the photo.

The summit region of Alu, ~5 km NW of the Dalafilla stratovolcano, is an ellipsoidal volcanic horst, elongated NNW-SSE, and formed primarily of older basaltic lava flows. Recent fractures along the axis of the Erta Ale range cut the main horst of Alu and areas to the SSE. Fumarolic activity is located on the numerous parallel faults. Fissure vents west of the horst have fed silicic lava flows, and voluminous youthful basaltic lava flows to the east extend north as far as Lake Bakili. Dalafilla, also referred to as Gabuli, is a steep-sided cone that rises 300 m above surrounding lava fields due to extrusion of viscous, silicic lava flows. Basaltic lava flows from regional fissures surround the volcano. Fumarolic activity occurs in the 100-m-wide summit crater and has weathered surrounding lava flows. The first historical eruption of Alu-Dalafilla took place in 2008, when lava flows from vents between the two edifices traveled NE.
