Studies of the Afar region played a major part in the development of these models

Just now there is a lot of volcanic activity accompanied by earthquakes in the Afar Rift Valley.
In the Afar region Mount Arteale, about 1,000 km northeast of Addis Ababa, erupted end of September 2005 after an earthquake measuring 5.5 on the Richter scale, and Some 50,000 nomads in Ethiopia's Afar region were displaced.

A few days later a quake, measuring 4.2 on the Richter scale, occurred in Teru (in Afar) and was followed by volcanic eruption. The quake, which struck the remote region of Afar, about 980 kilometres (600 miles) northeast of the capital, is said to be the 11th temblor to rumble across the region in about a month’s time.

All this seismic and volcanic activity is related to the movements of tectonic plates at the Afar Triple Junction (and the Great Rift valley). Ethiopia contains by the way 67 volcanoes, which is the most of any country in Africa.
