In the story I'm making that takes place on an alternate reality of earth in the 1300s, there is an all powerful being that makes all humans immortal. later on he gets angry that not everybody is worshipping him, so he turns everyone but a city of his closest followers into demons and causes disasters around the world. Assuming he can do anything at all, what could he do that would cause the continents to move around the world freely, or the earth move in a way that disregards its axis so that Russia would end up where Mexico is within 100 years?
For more context: After awhile a portal is opened between two alternate realities, the one with this version of Earth that's being destroyed and one where earth had different stuff happen but geographically its perfectly fine. The portal on the Earth being destroyed is on the continent of Russia, and the portal on the Earth that's normal is in central America, but its only between realities so the portal is technically in the same place on both versions of earth.
Back to the main question I'm asking, the all powerful being can do anything, but for story purposes he's only causing problems to punish everybody else on earth. He's not purposely moving the continents, the unstableness of the earth causes it. If so, I'd like a way for it to happen without completely destroying every living thing, but anything is good because the immortal humans will survive either way. As a side note, if a planet had two suns, would that be enough to cause it to ignore its axis?
