To go somewhat further on my previous idea. In the map above you see blue lines. Those lines are parallel with the track that Hawaii made in the past on the pacific plate in the red lines. First we have the somewhat horizontal lines which picture the today magnetic equator versus the more vertical lines which could picture the previous magnetic equator. Lets assume that these periods would take thousands of years. It would be logic that at each big period there are thriving civilizations before big catastrophes. If we would now take these crossroads as overlapping civilizations like for example very old ones and not so old ones like we see for example in Egypt and lots of other places then that could be a hint to look for older civilizations beneath younger ones and we could grasp the much older history of recent history of earth. Maybe we could also find geological evidences about those happenings.
