The Köfels Impact area in the Austrian Tyrol was identified by Alexander & Edith Tollmann as one of a number regions affected by an encounter with a comet/asteroid that resulted in its fragmentation prior to impact. The Tollmanns theorised that the flood of Noah and the Holocene extinctions were a consequence of these impacts.
The Köfels event has recently been linked in a book, A Sumerian Observation of the Köfels Impact Event, by Alan Bond and Mark Hempsell, to an Assyrian cuneiform tablet that apparently describes an earlier Sumerian observation of an encounter with an asteroid. The same encounter has also been suggested as the cause of the destruction of Sodom and Gomorrah.
In October 2015, there were reports that the sites of Sodom and Gomorrah had been finally located(a).
*November 2018 saw a further claim(b) that Sodom and possibly other the ‘cities of the plain’ (Gen. 13) had been destroyed by a meteoric airburst, similar to the Tunguska or the more recent Chelyabinsk events. This catastrophe took place north of the Red Sea in what is now Jordan according to archaeologist Phillip Silvia of Trinity Southwest University in Albuquerque.*
