* All data except CASTLE and TEAPOT data are’“obtained from Cratering
Produced by Nuclear Weapons, W.R. Perret, Sandia Corporation Techni-
cal Memorandum, Ref. Symbol 1922-2-(23) January 2, 1954.
#* All crater radii are measured at original ground level.
a Due to scour from water rushing back in, and ta aging (for GREENHOUSE) measured diameters may be large by 10 tq 30 per cent, mea-
sured apparent crater depths may be shallow by‘a facter of 2 or more.
b In Memorandum SWPEF 2/924 (354.2) dated 26 November 1954, the state- _
ment is made that plotting the IVY Mike data on an:‘expanded vertical
scale gives a value for crater radius of 2800 ft (A=il. 02).
