The 6.3 Magnitude tremor detected at a #NorthKorea test site would be consistent with the detonation of a hugely powerful Hydrogen Bomb

Just for reference: 5.6 is ~100 kilotons. 6.3 is a megaton. Just using Mb=4.05+.75Log(W). YMMV 3/

6.3 puts us up around a megaton. That would be a staged thermonuclear weapon folks. 4/

Ok, the better equation to use is probably Mb = 1.0125 log (Y) – 0.7875 log (H) + 5.887 where H is depth. 7/
