Lake-filled Ngozi caldera is seen here from its southern rim. The 1.5 x 2.5 km caldera lake is bounded by steep-walled cliffs 150-300 m high. The caldera is the most prominent volcanic feature of the Poroto Ridge, a transverse structure at the northern end of the Karonga basin in SW Tanzania. Numerous cones are situated along the ridge. The youngest activity along the ridge appears to have originated from Ngozi caldera and from pyroclastic cones to the N. Photo by David Williamson, CNRS, France.
