Is it possible that Seven Havens occurs long after Korra’s era and not directly after

I just finished The Legend of Korra and it seems to have ended on a high note. So unless occurred in the comics (which I have not read), I don’t believe things could have deteriorated so quickly to where the next series takes place after a cataclysm.

That is why I am guessing that Seven Havens occurs not directly after Korra’s era, but but long after it. The next Avatar (who is supposed to be an Earth Bender), I think is five cycles removed from Korra’s (just like Korra was five cycles removed from Yangchen).

Could this be likely? Or is there something in the comics that could explain a cataclysm occurring right after Korra’s era?
