So heres what happened in NK. Great leader publically says do a
test. Ooops it fizzled completely not a bit of fission. As an
alternative to execution the following morning, the head of the
nuclear project fills 10 rusty railroad cars with 50 tons of obsolete
damaged or old explosives in each car, and parks them in a partially
caved in railroad tunnel that was never repaired after the korean war
in the 50s. This takes about 12 hours to set up, to match how late
the supposed test was after the great leaders announcement. Western
world announces a late test with a partial fizzle of 500 ton yield,
little do we know it was actually conventional.
Its an internally self consistent theory that fits the evidence. It
can't be disproved without futher, presumably seismic, info.
So, here's the coldwar comms angle. The only way to answer this is
to transfer lots of seismic and mapping data around a foreign mostly
Is there the capability in the past, thus presumably the present, to
upload enough covertly acquired seismic data to do 3-D seismic
imaging like the oil companies do? If the boom was a point source it
was a real nuke. If the boom was from a cylindrical structure
roughly 10 feet wide and 300 feet long, it was faked.
Next, what was the coldwar comms plan for transfering map data?
Presumably after the big one hit, both sides would be missing all
kinds of bridges, canals, dams, and tunnels, so old maps would be
fairly useless. Now a days I figure they just instantly transfer
fresh maps over the computer network, but in the cold war days what
was the plan to distribute mapping data? Hand carried by courriers?
Radio fax machines? The relevance to the NK bomb is in the old days
it's probable the sesimic guys would be unable to get ahold of rail
and mining maps even if security allowed, although now only
institutional buracracy and stagnation would prevent the seismic guys
from overlaying the boom on top of a transportation and mining map.
The NKs might have used a partially caved in rail tunnel which would
be on old maps, but they might have used a brand new mine dug last
year that just didn't pan out so they may as well used the empty mine
for something useful, like a faked test.
So, the truth or not of the NK bomb can only be answered by coldwar
comms... At least thats what I think.
