成層火山 · Ethiopia · 988m

The prominent peak near the center of this NASA Landsat image (with north to the top) is Ale Bagu, also known as Ummuna. This elongated stratovolcano is the highest of the Erta Ale Range volcanoes. The main crater is the 750 x 450 m feature prominent in this image. The light-colored Roram Plain lies at the lower left, and lava flows from Hayli Gubbi volcano are visible at the right.

地質学的概要

Ale Bagu, also known as Ummuna, is an elongated stratovolcano located SW of Erta Ale volcano. In contrast to other volcanoes of the Erta Ale Range, it is located SW of the axis of the range, and is mantled by basaltic pyroclastic rocks. Summit craters are elongated along a NNW-SSE trend. The main crater is a steep-walled, 750 x 450 m depression occupied by a steep-sided lava cone that has fed trachytic lava flows over the crater floor. Silicic lavas from the axial regional fissure extend to the NW and SE.
