Thanks for the reply.
Any technical info on:
different Richter readings for blasts within water
vs. within ground
different Richter readings for small air-burst nuke
tests vs. in-ground tests of similar size
[Note: no tin-foil hat, just a desire to MAKE SURE]
[Note: other FReeper thread fed data into public-domain
code from Lawrence Livermore, HOTSPOT, to gauge
size of detonations from mushroom cloud, came up
with answer in low kilotons (tactical nuke or
nuclear trigger)... ]
The smallest nuke tests were the 5 done by Pakistan in response to India's 1998 blast. CNN claims that those tests measured 4.6 on the Richter Scale, while globalsecurity.org claims that they measured up to 5.0 at peak.
The Kursk conventional explosions measured 3.5 and 1.5. The North Korean blast this week measured 2.6.
The latest North Korean blast happened very near known ammo dumps and a volatile missile plant.
