Gelai Volcano and Crater Highlands, Tanzania
The Crater Highlands are a region along the East African Rift in Tanzania, located in a spreading zone at the intersection of branches of the African and Somali tectonic plates, resulting in distinctive and prominent landforms.
The highlands are named for the many craters present. As common in spreading zones, volcanoes can be found here.
Magma, rising to fill the gaps, reaches the surface and builds cones. Craters form if a volcano explodes or collapses and further spreading can fracture the volcanoes as well.
One of the most prominent volcanoes is the Gelai Volcano (center left), at the southeastern edge of Lake Natron in Africa’s Great Rift Valley, and northwest of Mount Kitumbeine.
The volcano, which stands 9,652ft (2,942m) tall, falls within a game-controlled area that extends east to Longido, where hunting is permitted. This has caused a drop in the numbers of animals in the area.
Longido is a town at the base of Mount Longido (center right).
