* 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).
