30. Actually, I was thinking...

more in terms of an operational screw-up type of accident, but we may never know with zero transparency. Also, we're unlikely to ever know the damage to the people and villages in the area, or to China's border areas. They must have collapsed a large system of tunnels or very large underground cavern to cause a magnitude 4.1 follow-up over 8-minutes later. Perhaps it could simply be a geological after-shock!

And, I'm finally getting your point about the initiator - primarily meaning a proper one for sizable fission devices, I assume.

Didn't even occur to me about the time-domain waveform of the shock being a specific nuclear signature. Most likely, the USGS and CalTech now have lots of historical signatures as reference. Perhaps not from the 50s though, when we blew up all of our toys.

Thanks for the reminder of http://thebulletin.org/. Have not visited them in a while. Will be watching their articles this coming week. Have a good Sunday.

That's more reasonable, and likely not a fusion device. longship Sep 2017 #20
