One recommendation... "Lucifer's Hammer."

Speaking of the effects of "Hydrostatic Shock" (or Seismic Shock in this case) One of the moons in the solar system shows the effects of an impact so large that it cratered one side of the planetoid and warped the opposing side where the shock waves interested at the mirror end of the sphere.

There is some evidence to suggest that our own moon was created in this fashion.

Massive Collision Created The Moon.

The Pacific ocean was left as the remnant of the loss of mass, Pangea (single land mass) the bulge at the opposite side of impact, Water left over from the comet that hit, and the Thermal heat of the core and subsequent volcanism a product of the transferred energy of an impact that ultimately transformed an old, cold piece of rock into a Paradise.

One might rather call that the 'Fist of God.'

I have been out of Archaeology and Geomorphology for sometime otherwise this might have been the subject of a dissertation. I would be curious to hear if anyone can expand on this theory.

"...I have been out of Archaeology and Geomorphology for sometime..."

This stuff is all old news anyway.

The moon is much older than the Pacific.

And there have been MULTIPLE "single land masses" on earth. There was Rodinia, which was a single land mass that split up scattering continents everywhere, then those continents came together to form Pangea. There may have been ones before Rodinia but Rodinia is the earliest one we can reconstruct well.
