Donald Sensing on the Yield Question
I dont mean to belabor the point I have made before, but I was trained in the Army as a nuclear-target analyst. A yield of 550-800 tons (.55-.8 KT) is not too small by any means as an achievable yield. It does not require a lot of fissionable material, either, which is one factor militating against the hoax conclusion. If the test was a proof of concept test rather than one intended to validate an actual warhead, then it makes sense for the DPRK to use as little nuclear material as possible. They dont get the stuff very easily.
Its also worth pointing out that an atomic bomb of .6KT or so is no city flattener, but would work quite spectacuarly as a terrorist weapon. If detonated on the ground or from the top of a building, it would also result in serious fallout, increasing the terror effect and the number of deaths. Further, it would contaminate the terrain at and near ground zero for a long time. Cleanup and decontamination would be lengthy and very expensive. Imagine such a weapon being detonated in an American harbor.
Using the US Geological Survey figure of 4.2 magnitude body wave of the seismic shock, giving a 1 KT achieved yield, actually buttresses the case that this test was not a fizzle, in my view. For battlefield purposes, say, against the South Korean or US forces on the peninsula, a 1 KT device is more usable than a 20 KT bomb. A 1 KT weapon is smaller, thus easier to conceal, and can be designed to be fired from existing artillery pieces, whether cannons or rockets. A Nagasaki-yield weapon would be of little military utility in fighting against South Korea or American forces. And you much more easily can get from a tested 0.6-1.0 KT proof-of-concept device to a usable terror weapon of the same yield, than from a test of a much larger yielding device.
