For what it’s worth, the USGS seismic magnitude for the NK 2006 fizzle was 4.2. The preliminary magnitude of 4.7 for this one is more than 3x higher. But there are so many factors involved in transferring the explosion energy into the surrounding rock…, we’ll just have to wait and see.

Let’s just say the Hiroshima bomb was 15KT over half a century ago, the first “successful” nuclear test by North Korea was less than one KT, and anyone serious about nuclear weapons nowadays, measures yield in tens of MT.

/granted North Korea shouldn’t even be allowed to experiment in this realm, but I’m not going to start panicking until I see how large this detonation was and if it was even nuclear
