Reportedly the test was conducted in a region with less than optimal geographic properties (i.e. soft substrate). Which leads me to wonder ...
WHY?
Perhaps NK took a leaf out of the US's research book, and detonated their nuclear device in an excavated chamber in a salt dome - just as the US
Government did in 1966.
If the test was conducted in an underground salt dome, it is unlikely that radioactive gaseous by products of the detonation will reach the surface,
which would make verification extremely difficult.
This would also explain why the seismic shock wave was not as large as expected.
The process of detonating an underground nuclear device in a chamber, is known as 'decoupling', and is quite widespread knowledge. It can muffle a
seismic wave by up to 70x.
