Great Rift Valley

Rift ValleyGreat RiftEast Africa's Great Rift Valley
In the past it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor.
Today, the term is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward across eastern Africa, and is in the process of splitting the African Plate into two new separate plates.

Gregory Rift

Eastern Rift ValleyGregory Rift ValleyEastern Rift
The Eastern Rift Valley (also known as Gregory Rift) includes the Main Ethiopian Rift, running eastward from the Afar Triple Junction, which continues south as the Kenyan Rift Valley.
The Gregory Rift is the eastern branch of the East African Rift fracture system.

Albertine Rift

Western Rift ValleyAlbertine Rift MountainsAlbertine
The Western Rift Valley includes the Albertine Rift, and farther south, the valley of Lake Malawi.
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania.

Lake Malawi

Lake NyasaMalawiLake Nyassa
The Western Rift Valley includes the Albertine Rift, and farther south, the valley of Lake Malawi.
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania.

Great Rift Valley, Ethiopia

Great Rift ValleyRift ValleyMain Ethiopian Rift
The Eastern Rift Valley (also known as Gregory Rift) includes the Main Ethiopian Rift, running eastward from the Afar Triple Junction, which continues south as the Kenyan Rift Valley.
The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction.

African Plate

AfricanNubianNubian Plate
The rift, a narrow zone, is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6-7 mm annually.
Between and, the Somali Plate began rifting from the African Plate along the East African Rift.

Ethiopia

EthiopianAbyssiniaFederal Democratic Republic of Ethiopia
The EAR transects through Ethiopia, Kenya, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi and Mozambique.
Its capital and largest city is Addis Ababa, which lies a few miles west of the East African Rift that splits the country into the Nubian and Somali tectonic plates.

Afar Triple Junction

Afartriple junction region
The Eastern Rift Valley (also known as Gregory Rift) includes the Main Ethiopian Rift, running eastward from the Afar Triple Junction, which continues south as the Kenyan Rift Valley.
Here, the Red Sea Rift meets the Aden Ridge and the East African Rift.

Africa

The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa.
Between and, the Somali Plate began rifting from the African Plate along the East African Rift.

Red Sea Rift

Red SeaRed-Sea rift
To the north of the Afar Triple Junction, the rift follows one of two paths: west to the Red Sea Rift or east to the Aden Ridge in the Gulf of Aden.
It extends from the Dead Sea Transform fault system, and ends at an intersection with the Aden Ridge and the East African Rift, forming the Afar Triple Junction in the Afar Depression of the Horn of Africa.

The EAR transects through Ethiopia, Kenya, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi and Mozambique.
Burundi is a part of the Albertine Rift, the western extension of the East African Rift.

Graben

It also runs offshore of the coast of Mozambique along the Kerimba and Lacerda grabens, which are joined by the Davie Ridge, a 2200 km relic fracture zone that cuts across the West Somali basin, straddling the boundary between Tanzania and Mozambique.

Rwanda

Republic of RwandaRuandaRwandan
The EAR transects through Ethiopia, Kenya, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi and Mozambique.
They are part of the Albertine Rift Mountains that flank the Albertine branch of the East African Rift, which runs from north to south along Rwanda's western border.

The rift, a narrow zone, is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6-7 mm annually.
The western boundary with the African Plate is diverging to form the East African Rift, which stretches south from the triple junction in the Afar depression.

Malawi

The EAR transects through Ethiopia, Kenya, Uganda, Rwanda, Burundi, Zambia, Tanzania, Malawi and Mozambique.
The Great Rift Valley runs through the country from north to south, and to the east of the valley lies Lake Malawi (also called Lake Nyasa), making up over three-quarters of Malawi's eastern boundary.

Mount Kenya

Mt. KenyaBatianMt Kenya
The East African Rift Zone includes a number of active as well as dormant volcanoes, among them: Mount Kilimanjaro, Mount Kenya, Mount Longonot, Menengai Crater, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon, as well as the Crater Highlands in Tanzania.
Mount Kenya is a stratovolcano created approximately 3 million years after the opening of the East African rift.

Tanzania Craton

A 3D numerical geodynamical model of the plume-crust coupling was capable of reproducing the lateral asymmetry of the EAR around the Tanzania craton.
The craton divides the east and west branches of the East African Rift.

Crater Highlands

Ngorongoro Highlands
The East African Rift Zone includes a number of active as well as dormant volcanoes, among them: Mount Kilimanjaro, Mount Kenya, Mount Longonot, Menengai Crater, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon, as well as the Crater Highlands in Tanzania.
The Crater Highlands (Ngorongoro Highlands) are a region along the East African Rift in the Arusha and Manyara Regions of northern Tanzania.

Mount Karisimbi

The East African Rift Zone includes a number of active as well as dormant volcanoes, among them: Mount Kilimanjaro, Mount Kenya, Mount Longonot, Menengai Crater, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon, as well as the Crater Highlands in Tanzania.
At 4507 m, Karisimbi is the highest of the eight major mountains of the mountain range, which is a part of Albertine Rift, the western branch of the East African Rift.

Ol Doinyo Lengai

Oldonyo LengaiOldoinyo LengaiLengai
Active volcanos include Erta Ale, DallaFilla, and Ol Doinyo Lengai, the former of which is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia.
Part of the volcanic system of the East African Rift, it uniquely produces natrocarbonatite lava.

Northern Cordilleran Volcanic Province

Stikine Volcanic Belt
It has formed due to extensional cracking of the North American continent—similar to other on-land extensional volcanic zones, including the Basin and Range Province and the East African Rift.

Mantle plume

Although reasonably considered, the exact conformation of deep-rooted mantle plumes is still a matter of active research.
Well-known examples are the Basin and Range Province in the western USA, the East African Rift valley, and the Rhine Graben.

Erta Ale

Active volcanos include Erta Ale, DallaFilla, and Ol Doinyo Lengai, the former of which is a continuously active basaltic shield volcano in the Afar Region of northeastern Ethiopia.
Erta Ale is centered over the East African Rift system, which is a triple junction setting whose movements are resulting in the formation of a pull-apart basin or rift.
