There was quite a crater at the OKC bombing, although not quite as deep it was probably a smaller explosion than this one.

There was no crater at the Murrah building in OK city, you may be thinking of the clearing efforts that involved the basement. The ANFO in the truck destroyed the front of the building and caused a collapse of the upper floors.

The NK explosion is more indicative of a projectile or something planted beneath the surface.

I was thinking the same thing.
