I guess it's possible? I mean, Dalamud didn't crash and was stopped before by Louisoix, but many pieces hit the ground and caused immense damage everywhere on Eorzea. I can imagine that pieces of that magnitude, with enough speed and mass, can definitely provoke tsunamis when they fall into the water.Â
Something you might want to consider though that for the chunks we have seen that fell on the surface (cf Coils of Bahamut), they seem to have so massively killed everything around that huge spires of crystalized aether and corrupted aether have risen all around, like in La Noscea, the Shroud and Thanalan.
It's... well, maybe there are others in the world, but they probably are landmarks.
Also, if your isle was protected, out of curiosity, why would your character have an extra motivation to come to Eorzea?
