Have you seen the TV documentary about the theory it was an air-burst from a asteroid that was tracked by an ancient astronomer and recorded on a clay astrological chart found in the region now known as Iraq?
They also connect the asteroid to one that sheared off the top of a mountain in Austria on its trajectory south toward the Levant.
Very cool info in that documentary. Speculative, but with some physical clues that support it.
When Saddam Hussein drained the Iraq Marshes, a 2 mile diameter depression was found, suggesting a bolide strike. Couldn’t find if any recent work has been done to verify origin because of warfare. At any rate, one suggestion is that it is from around 2200 BCE, which is just about what this article suggests. Lots of civilizations fell apart around this time. There could have been more than one event, including one or more bolide strikes, a Tungusku level air burst, etc.

I ran across an account of the search for the Wabar meteors in an older National Geographic. Although the age does not seem to be connected to either Sodom or the Iraq Marshes, the story the author was told is that this fall destroyed a city for its wickedness. I guess if God would destroy something this way it must because of the wickedness of the people.
