This is a really interesting area geologically. Just some cursoury research shows that the Afar Depression is a rift valley formed by the divergence of three plates. This is one of the few areas that are land observable oceanic rifts. It looks like it is essentially creating new seabed on land.
That's my understanding too. Some day those volcanos will be islands in an inland sea.
Quoting: Brassia RexOr they will be volcanoes within the new continental margins, just as in other areas of the world... that are thought to be "subduction" zones, which is ridiculous... both things are possible For now this "rift valley" is in the process of transforming into an oceanic rift, an ocean floor spreading area... but it rather is much more... continental expansion still. Volcanoes are weak points in the crust and they seem to have a strong trend toward keeping in existence for very long geologic timeframes, incredibly long, perhaps... they just grow over and over themselves... and have changes.
