Probably hacked into the seismic network from the N.K. Internet.
1 kilo down but 0 distance from seismogram?
Could NK just send in the info and fake it?

I suppose they could set off a really big conventional explosives pop but it’s most likely real. We’ll be looking for any leakage that’s radioactive. Plus the seismologists are saying the earthquake is atypical meaning induced by an explosion.
I’m not real comfortable with strange creatures having nuclear toys.
