[Japan] insists that the event was not a nuclear test, because "A nuclear explosion creates seismic waves, and no such activity was detected". That's not true at all - seismometers in California had no trouble at all detecting the event. In fact, if you compare some of the publicly available [seismographs] (local copy - [source]) with information from a national lab's [forensic seismology] primer, you'll see that not only was the event detected, but it has all the characteristics of an explosion rather than a natural event.
Not only does this make Japan's assertion that there was no seismic data seem odd, but it also calls into question some American conjecture that the event was the result of a ["forest fire"].
Tonight North Korea claimed that the event was part of a planned demolition for a hydro electric project. If the news agencies reporting on this had published satellite photos from Space Imaging immediately, there wouldn't be much of a question what happened. [Soon] they may not even have the option, but they certainly don't seem to be exercising that now.
The day of the event was the anniversary of the founding of the DPRK, which is probably more than a coincidence.
