Detection[edit]

One thing which should be covered in this article is the issue of detecting underground tests; the issue of whether or not underground testing could be hidden, or could have the yield obscured, or could be detected correctly at all, has been very important since the 1950s or so at least. Just noting that here for future reference. --Fastfission 03:20, 17 December 2006 (UTC)

Good point. There is some information in the Amchitka article on the early work on this. Additionally, Caging the Dragon has some useful material. I'll try to look at this over the next few days, unless someone else wants to do so first. Jakew 14:13, 17 December 2006 (UTC)

Depth[edit]

How far underground did they place the bombs? 118.208.209.188 (talk) 11:50, 17 February 2009 (UTC)

It depends on the device that's being tested, and its expected yield. A large bomb needs to be buried more deeply in order for it to be contained. The largest underground test was Cannikin at the island of Amchitka; that was buried 5,875 feet deep (10.1 miles), and yielded about 5 megatons. Jakew (talk) 13:24, 17 February 2009 (UTC)

Renaming section[edit]

It seems that "Early history of underground testing" should be renamed to "Early history of American underground testing". A quick look-over shows that all measurements are in feet, so I assume that this is the case. Esn (talk) 21:17, 25 May 2009 (UTC)

Standing on it![edit]

What would happen if someone stands on the ground of a contained underground nuke like Cannikin? Waist broken? Gibs flying? —Preceding unsigned comment added by 91.99.164.211 (talk) 20:57, 26 February 2010 (UTC)

Displacement of surface[edit]

Can an fully-contained underground blast create an underground cavity without creating a mound on the surface equal in volume to the cavity? If so, how is the mass that once occupied the cavity accounted for? —Preceding unsigned comment added by 206.55.142.146 (talk) 00:08, 7 April 2010 (UTC)
