We have a nuke capable of penetrating harded surfaces up to 250 feet, after detonation, everything 2 miles downs and 5 miles in circumference collapses below ground level, the shock wave kills everything that is breathing. The fallout yeild is very low except in the immediate area of the explosion and the debris cloud that forms, which, depending on the wind conditions, it nominal. Above ground, only about 1/2 mile circum. is destroyed.
Edit: This nuke was once used to experiment with the peaceful use of mining with nukes. The DoD shelved the product but kept several varieties of this type of weapon in inventory.
