Discussions focus on geological processes affecting Earth's crust, including plate tectonics, post-glacial rebound, continental drift, mantle features, and theories like crustal displacement or pivoting.

Maybe it's something at the interface between the lower and upper mantle ;)
It's very weird for someone like me that does not work in geology [1], but apparently it is quite well documented https://en.wikipedia.org/wiki/Large_low-shear-velocity_provi... It has an animation that is very nice to understand the location and size.[1] Relevant xkcd: https://
Check out 'Earth Crust Displacement Theory' and go look at the ocean floors on google maps to get your mindblown
Won't tides effect all parts of the earth not just the crust?
You don't consider that "tectonic activity"?
... what's the origin, when the entire surface of the Earth is sliding around?
This was the Earth's crusts doing a 'pivot'. Probably quite disruptive.
Oceanic crust vs continental crust
Depression formed on the surface of the earth?
They do. Search for Jerry Mitrovica (Harvard geophysicist) on YT for explanations.
