If only man-made artifacts are displaced, but not the terrain, that must be a
mapping error. An actual earthquake land-shift would have displaced the
terrain, and moved buildings

I noticed the same on the southern coast of Haiti as well (I have been doing
some mapping in and around Jacmel), with some oddities where features and
ocean collide, with the ocean being too far inland - and editing of the
coastline
If you look at the coast of Haiti, west of port-au-prince
some strange artifacts are shown on a lot of places where
building and beach clubs (I presume) touch the coast line.

Sounds like buildings drawn precisely from high-res but poorly
georeferences aerial photos.
Looking at a sat-image you don´t know if not all of that photo is 50

are on the ground to compare.

WMS are with serious offset and no one haven't provided GPS references
yet. Maybe that's the reason.

My first guess was that these were the foundations of the houses but
it may be some kind of rubble that slid into the water. I don't know
