FOXNEWS per Bush admin official - NKoreans may not have gotten what they wanted (under 400kt level)

Based on info here, and knowing that the Richter scale is exponential, the size seems very low, like < 10 Ktons.

Caveat: Depth, rock make-up, etc can certainly make all of my assumptions absolutely incorrect.

Thanks. Fox source phone interview just said "not a usable nuclear weapon indicated by this test."
