Thanks for the information all. Watching the video of the underground test reminded me of when I was kid (7-10 years old) and remembering the old AEC used a small nuke in Colorado for test for mining purposes and ended up with a good size earthquake from the test because it took place near unknown fault lines. The info from Nuke11 was precisely what I was looking for, and THANK YOU ALL!
