Volcanic tremors and the forces that are pulling the plates apart combine to break the weakened and thinned crust into earthquake-generating faults. … When the faults slip, one side rises while the other falls. Over time, steep mountains form along one side of the fault.
What causes the earthquakes in Africa?
According to earth science consultant Dr Chris Hartnady, “This part of Africa is in the vicinity of the African Rift system, which is being pulled apart by a few millimetres annually.” He says “earthquakes are caused by a slip on a fault line and the release of stored elastic energy” and mining activity can trigger …
Are earthquakes common in East Africa?
East Africa. East Africa is one of the first regions to be considered seismic in Africa, and this was because of the occurrence of earthquakes with high magnitude and intensities.
Where do most earthquakes occur in Africa?
The majority of seismic activity is concentrated along the East African Rift System, with additional active regions along stretches of the continental margins in north and east Africa, and in the Congo Basin.
Does Kenya suffer from earthquakes?
It is shown that relatively large but infrequent earthquakes do occur in the Kenya (Gregory) Rift Valley, a slowly extending region of low apparent seismicity, and that the seismic hazard of this part of East Africa, deduced from data of the last 95 years, is significant.
What are the 3 main causes of earthquakes?
5 Main Causes of Earthquakes
- Volcanic Eruptions. The main cause of the earthquake is volcanic eruptions.
- Tectonic Movements. The surface of the earth consists of some plates, comprising of the upper mantle. …
- Geological Faults. …
- Man-Made. …
- Minor Causes.
Is Africa tectonically active?
Continental rifting requires the existence of extensional forces great enough to break the lithosphere. The East African Rift is described as an active type of rift, in which the source of these stresses lies in the circulation of the underlying mantle.
Why does Africa have no earthquakes?
As has been said a lot already, Africa does get earthquakes, just much less of them. The reason Africa gets less earthquakes is because of the tectonic plates. Where two plates connect is where you get earthquakes.
Are there earthquakes in Horn of Africa?
The Horn of Africa has significant seismic hazard associated with the East African rift system. A number of destructive earthquakes, some deadly, have been reported this century.

Does Africa get many earthquakes?
Africa actually gets MANY earthquakes, most of which are in the Great Rift Valley, which is located in the eastern part of the continent. In Africa, the Great Rift Valley runs through Ethiopia, Kenya, Tanzania, Malawi, and Mozambique.
Is there any volcano in Africa?
Nyamuragira is Africa’s and one of the world’s most active volcano. It erupts roughly every two years, producing large fluid lava flows. Nyamuragira is is a massive high-potassium basaltic shield volcano located about 25 km north of Lake Kivu in the East African Rift Valley NW of Nyiragongo volcano.
Is Kenya on a fault line?
The Southern Kenyan rift valley consists of numerous fault blocks encompassing horsts, grabens and step-fault platforms that are very little modified by erosion (Baker, 1953, p. 1).
What was the biggest earthquake in Kenya?
Furthermore, historical records show that earthquakes of magnitudes of the order of Ml ⩾ 6.0 have occurred in Kenya. Such large magnitude earthquakes include the January 6, 1928 Subukia earthquake (Ml 7.1) and an aftershock (Ml 6.2) four days later, as well as the 1913 Turkana region earthquake (Ml 6.2).
Who is Makori Ongechi?
