The Köfels Impact area in the Austrian Tyrol was identified by Alexander and 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^[426], 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.
