“Now some scientist here needs to devise a way to create a directional tsunami...”
My thought was a good storm will make those islands disappear. Real islands have substantial bases. These are sand bars. I’ve seen hurricanes remove or move entire islands. Hurricane Pass in Florida, for example.
They probably have those sand bars sea walled and shored up so they don’t lose all their expensive s*** in a typhoon-that’s why I suggested a helpful tsunami...
