Thanks for the ping to the seismo data!

Located at http://www.freerepublic.com/focus/news/2257598/posts?page=227#227 is a seismogram I posted earlier. It is from Inchon, SK, and is from an instrument with lower gain and at a different bandwidth. It shows the blast as an isolated impulse.

Also, you might appreciate the satelllite imagery analysis I posted at http://www.freerepublic.com/focus/news/2257598/posts?page=254#254, which shows a likely candidate site for the test very near the coordinates indicated by seismometry.

Interestingly the revised coordinates (41.285°N, 129.004°E) in Cindy's updated seismo data place the event only 1.5 klicks from the candidate site I posted at http://www.freerepublic.com/focus/news/2257598/posts?page=254#254 earlier this morning.

Furthermore, the new coordinates are south of the candidate site -- neatly bracketing it and on a N-S line passing through all three points.

I think I nailed it!

Here's the revised satellite image -- showing the probable test site location.
