Mount Rungwe: Introduction

Thu, 23 Apr 2026 00:00:00 GMT

Three rift valleys meet here, and the earth has not finished deciding what to do about it. Mount Rungwe rises 2,981 meters above Tanzania's Southern Highlands, a stratovolcano perched on the seam where the eastern and western branches of the East African Rift converge with the Usungu Rift to the northeast. The mountain last exploded about 1,200 years ago, scattering ash across the landscape now planted with banana groves and coffee. It is officially inactive. Geologists use a more careful word: dormant. A four-kilometer-wide caldera sits on the summit, breached to the west-southwest, the mouth of something that has not spoken recently but has not spoken its last word either.
