Earthquakes in Africa are largely restricted to the East African Rift. Here the continent has been slowly attempting to rift apart during the last 30 million years. At its northern end the East African Rift joins the spreading ridges of the Red Sea and Gulf of Aden, which completely rifted Saudi Arabia away from Africa also starting about 30 million years ago. That rifting event evolved to completion, whereas the East African Rift has not. Following the East African Rift to the south, it splits around Lake Victoria into two arms. The eastern rift runs through Kenya and Tanzania, whereas the western rift is marked by the elongate lakes on the W borders of Uganda and Tanzania. Both arms of the rift have abundant earthquakes and active volcanoes.
