Of the three maps that are posted here, each is radically different it seems (the cut up one though maybe I don't understand).

Something that strikes me is that the one without any writing on it, seems to work only on flooding levels, if nothing changed and all that it concludes what parts of the world would be under water.

The one that you can make a globe out of, I won't discuss, because I don't quite understand it. Apart from the equator turning 90 degrees and an emergence of an arctic continent plus india and australia under water, there doesn't seem to be much change, but correct me if I'm wrong.

Now what I wonder is why the map from the photo has such substantial changes. What is it based on? How is it that continents emerge? Volcanic eruptions under water?
Furthermore, does it work on the basis of 'unstable' and thus sinking landmasses? Some areas I think consider rather high up are flooded while others at lower altitude seem to be above ground.

In my case I have special interest in Japan, the photo map shows Japan completely submerged, yet Australia is just fine. This is exactly the other way around in the first map I mentioned.

Anybody care to enlighten me?
