Only in recent times with modern engineering did we build and live in areas that would flood in any storm or high water. The ocean is a stormy place, and without modern structures, they'd be more vulnerable to weather unless they built just on the other side of the historical dunes and high water areas.
Or maybe they can tell, I don't know. I don't wish anything so, I just wonder.
Actually the opposite is probably more accurate. A major percentage of the world's population still resides along rivers, canals, ports, and surf.
The 'Remote Viewing' topic and those associated with it such as Dames are also closely associated with very direct occultic behaviors. (His name and associates is about as close to being directly linked with 'devil worship' within DOD/Intel as I've observed.)
There is a lunatic fringe associated with that language, more technically inclined than, say, dowsers or hypnotists, but just as adament in its success.
I would tend to be gracious as classify it as a 'spiritual' phenomenon, however, IMHO there is another question as to whether the spirits involved are malevolently deceiving or sent by God.
I understand your point.
But it has, evidently, nothing to do with this area of the globe.
It is clear from the devastation that flimsy buildings, homes were plentiful on the beaches throughout the area.
And this doc asserts that these tribal people also dwelt near the beach.
BUT THEY LEFT AND WENT UP INTO THE HILLS/MOUNTAINS DAYS BEFORE THE DISASTER.
I can accept that at face value. I don't need to invent things to explain it away.
