This webpage will help you predicts the crater size and the damage on the underground structures following nuclear weapon explosion.

Nuclear weapons explosions from testing are forming huge craters that can led to people around the explosion site getting radiation sickness and various types of cancer and even death

Here some Craters formed after Nuclear explosion in the USA and around the world:

For more information about Cratering and Crater types see Nuclear weapons effects

Heavy or small underground strutures will be damaged only if they are 1.25 apparent crater radii of a nuclear explosion. 

For a specific crater size and damage, choose the energy yield of the nuclear weapon explosion (kilotons):

Enter the energy yield in kilotons: Detonate
