Makes sense. The only problem though is the wells proximity to land and the bomb would need to be on the seafloor or atleast close enough.

I wonder what the minimum size nuclear bomb would be needed.

Since the bomb would be on the floor, the shockwave will carry a tsunami to the shorelines, easily. In fact, there will be a double shockwave ripping through the water. One from the bomb and the other being a seafloor reflection.

The massive displacement of water will definately create a tsunami. No doubts.

We all know nukes were detonated in the Pacific but that was far from the seafloor so the wave created could dissipate before reaching shore. A much different situation for the Gulf.

Plus the well head is in a valley of sorts.

In fact, I wonder if they could cause a large landslide to roll on top of the well head(s). Though, that too would create a massive tsunami.

Either way, I think the Gulf Coasts are going to be hit hard. Think of it this way, if you had a choice... The Worlds Oceans or the Gulf Shores.

Doom for sure!
