English: Two closely spaced volcanic centers, Boset (Boseti-Gudda) and Bericha (Boseti-Bericcia) are composite dominantly rhyolitic-to-trachytic volcanoes rising above the floor of the Ethiopian Rift valley. Boset, the SSW center (also known as Gudda), is below and to the left of the center of this Landsat image, while the NNE center, Bericha, lies just above the center of the image. Fissures connecting Boset and Bericha have erupted youthful, prehistorical basaltic lava flows.
