That’s hardly a flood though. A flood is the village disappearing in day or two. Disappearing in a decade or two? I’m not sure what I would call that, but definitely not a flood.
This is exactly what happened in the British Isles when low lying Doggerland (between modern England and Denmark) was wiped out by a wave which was likely caused by an underwater landslide; that wave was in turn caused by the melting ice at the end of the ice age, which was otherwise causing gradual sea level increase.
I harbor doubts about their receptivity to the correction.
