It's where two tectonic plates, the Eurasian plate and the African plate, are slowly colliding.

欧亚板块和非洲板块这两个构造板块正在缓慢碰撞。

From an analysis of the hot-spot population it appears that the African plate is stationary and that it has not moved during the past 30 million years.

从对热点人口的分析来看，非洲板块似乎是静止的，并且在过去 3000 万年里没有移动。
