knock yourself out and do the math yourself.
Some of the test results of surface bursts contain crater depth and diameter, though I guess these things are subject to variation depending on the surface.
I assume it's not as easy to put a dent into a mountain + reinforced concrete or whatever they'd be using to build their labs.
Feel free to compare the data to penetration capabilities of modern bunker busters.
You should also consider that the bigger craters have been cause by H-Bombs - those things have an enormous yield - not something you'd use on a whim.
Post results pf your research here if possible, so we all benefit from it.
