Question: how much can 1 nuclear bomb destroy?
Answer: 1 megaton bomb can create a firestorm that can cover 100 square miles, a 20 mega bomb can have a 2500 square mile firestorm. But the “total destruction” blast radius for the tsar bomb is 22 miles but every small building in a abandoned village that was 34 miles away was leveled. So it really depends on the size.
