The changes in the continents are far beyond that possible by a lunar cry. While the crater in Trabia may be the result of a lunar cry, and a lunar cry may have wiped out the Centra civilization, these are incredibly minor compared to the differences we see between FFIII's and FFVIII's worlds.

As well, if a lunar cry were capable of such power, wouldn't Esthar have been wiped out?
