crockett: here are my calculations for 20 Mt:
- 3.65 * sqr3(20) = 9.8 km (301 square km) - total destruction
- 7.5 * sqr3(20) = 20.25 km (1287 square km, which is about equal to the size of NYC) - heavy destruction and firestorm
- 14 * sqr3(20) = 37.8 km (4486 square km) - slight destruction and separate fires
According to
Wikipedia, the size of Denver is 400 square km. So, how many 20 Mt warheads will be enough to destroy it?
P.S. 9.8, 20.25 and 37.8 above are radius sizes, calculated based on reference ones for 1 Mt explosion.
