I've been following the thread and agree that crustal displacement is a possibility.

I've added a few pictures that I acknowledge could have been caused by either crustal displacement or by planetary impact by another object such as a comet or moon.

Both of those events could have caused the below results.

Take the Moai of Easter Island in example. They are full sized statues that have been buried in over twenty meters of silt.



But it was not just a gradual accumulation of dirt, whatever buried them struck with great force, force enough to tilt many of the massive statues over.



This force could have been the ocean waters themselves, heaved up out of their basins as the crust of the entire planet slid with great violent effect over the mantle below and the water was left to its own devices to 'slosh' over all of the land.

What other evidence is there?

One need only look so far as Southern Madagascar [on the other side of the world!] to see evidence that the ocean there was forced up from its basin to wash across the land leaving the 'chevron like' sediment deposits upon the land.

Either of these events could have been caused by crustal displacement or planetary impact.

Since the 'timing' is not precise, I'm more inclined to believe it results from a gradual buildup to slippage that occurs with regularity yet with indeterminate time between the events.



One can also see the possible result of crustal displacement in Tiwanaku, where the massive structure of 'H blocks' lies in ruins.



And what of the wall covered in the faces of mythical gods or ancient aliens that was found buried under meters of silt near the same site.



We are seeing global evidence of an event, an event that reshaped the earth. One that may even have changed the location of the earth's equator, or rather the land that now lies above the earth's equator.
