As I pointed out, the OP is an SBI. That was not intended as mockery, and I apologise if it is taken as such. I was merely trying to convey reality in a way that could not be mistaken. We all have the occasional SBI, and it is good to have this pointed out. Adding a second tsunami to the first cannot help. A tsunami cannot be controlled in that way, we merely end up with two, rather than one, devastating tsunamis. There is a giant mountain, an occasionally active volcano, in the Canary Islands, with half its mass poised to fall into the sea. If an eruption happens, and the mass topples into the sea, the resultant tsunami will wipe out the whole American eastern seaboard. It will also devastate the Caribbean, and western Europe, since those waves go in all directions. There is no way we can, even in theory, prevent or mitigate this, or any other, tsunami. Fortunately, there is no reason to suspect that it will happen this side of a million years, though it might, in theory, occur tomorrow. Life is a lottery!
