In the event of a seventh Century tsunami, would there not have been some refernce to this historically?

Depends on whether any witnesses survived, I suspect. The Mutton Island tsunami killed at least a thousand in 9th c Ireland, and though I tend to read up on natural catastrophes, I’d never heard of it until 2005.
