A third major plantion surface and uniformity formed in the following a tectonic event in the Early Cretaceous that tilted carbonates in the Tigray and Dire Dawa-Harar areas. [1] On top of this surface lies a series a fluvial sediments. [1] Depositions of marine sediments continued in eastern Ethiopia's Ogaden basin until the Eocene. [1]
Erta Ale erupting within the Danakil Depression Mount Ayalu, the westernmost and older of two volcanoes at the southern end of the Danakil Depression. The Danakil Depression is the northern part of the Afar Triangle or Afar Depression in Ethiopia and Eritrea, [1] [2] a geological depression that has resulted from the divergence of three tectonic plates in the Horn of Africa.
The Blue Nile Basin is a major geological structure in the northwestern Ethiopian Plateau formed in the Mesozoic Era during a period of crustal extension associated with the break-up of Gondwana, and filled with sedimentary deposits. The modern Blue Nile river cuts across part of the sedimentary basin. [1]
This article describes techniques; for a history of the movement of tectonic plates, see Geological history of Earth.. Plate reconstruction is the process of reconstructing the positions of tectonic plates relative to each other (relative motion) or to other reference frames, such as the Earth's magnetic field or groups of hotspots, in the geological past.
Sanetti Plateau in Ethiopia. Ethiopian wolf with Helichrysum citrispinum - both are endemic species. The Sanetti Plateau is a major plateau of the Ethiopian Highlands, in the Oromia Region of Ethiopia. The plateau is the highest part of the Bale Mountains, and is located within Bale Mountains National Park. [1]
The Bale Mountains are separated from the larger part of the Ethiopian highlands by the Great Rift Valley, one of the longest and most profound chasms in Ethiopia. The highest peaks of that range include Tullu Demtu , the second-highest mountain in Ethiopia (4,377 m or 14,360 ft), Batu (4,307 m or 14,131 ft), Chilalo (4,036 m or 13,241 ft) and ...
There are 12 World Heritage Sites in Ethiopia, with a further six on the tentative list. [3] The first two sites in Ethiopia added to the list were the Rock-Hewn Churches, Lalibela, and the Simien National Park, both at the Second Session of the World Heritage Committee, held in Washington, D.C., in 1978.

The Gregory rift is oriented NS, and in the past the minimum horizontal tectonic stress direction was EW, the direction of extension. The alignment of rows of small vents, cones, domes and collapse pits in the Suswa, Silali and Kinangop Plateau regions support this theory. However, data from oil and gas exploration wells in Kenya, vents in ...
