Magmatic activity across the East African North Tanzanian Divergence Zone
Volcanism across the North Tanzanian Divergence Zone (NTD), part of the East African Rift System, occurred episodically from the late Miocene to Recent. Here, we present a summary of previously…

Kilimanjaro National Park
The free-standing mountain of Kilimanjaro is a giant edifice comprised of three discrete volcanoes. They collectively cover an area of 6,000 km2. The two lowest peaks, Shira and Mawenzi are eroded…
Lithospheric low-velocity zones associated with a magmatic segment of the Tanzanian Rift, East Africa
Rifting in a cratonic lithosphere is strongly controlled by several interacting processes including crust/mantle rheology, magmatism, inherited structure and stress regime. In order to better…
Sector collapse events at volcanoes in the North Tanzanian divergence zone and their implications for regional tectonics
The North Tanzanian divergence zone along the East African Rift is characterized by active faults and several large volcanoes such as Meru, Ol Doinyo Lengai, and Kilimanjaro. Based on systematic…
Depositional history of Lake Chala (Mt. Kilimanjaro, equatorial East Africa) from high-resolution seismic stratigraphy
<p>Sediments deposited in Lake Chala constitute a high-resolution archive of past climate and environmental change in equatorial East Africa spanning two glacial-interglacial cycles. To correctly…
