The tectonic structures in the Great Rift Valley are amongst the most
studied on the planet. We are better equipped today to distinguish volcanic
craters from meteoritic ones- I expect that the geology of this caldera is
fairly well understood. It certainly couldn't be older than a few million
years given the degree of uplift in the area.

A personal observation (and quite non-expert) is that this structure's
eccentricity argues against an impact origin.
