COMPARISON OF SPECTRA OF AN EARTHQUAKE T-PHASE WITH SIMILAR SIGNALS FROM NUCLEAR EXPLOSIONS Milne, A.R. Bulletin of the Seismological Society of America (U.5S8.) v 49. Publication Date: (1959) Oct. 317-29 p. Coden: BSSAA i Note: 0037-1106 Journal Announcement: NSA14 Document Type: Journal Article Language: English , Hydrophones from a surface vessel in 1,300 fathoms of water off Juan de Fuca 9trait detected, in the course of the ""Hardtack"" series of tests in the Marshall Islands, 3 acoustic signals which had peaks in their energy spectra at frequencies less than 20 cps. Two of these appear to have originated from nuclear explosions; the third, though having a similar energy spectrum, was apparently a T-phase from an earthquake near Cape Mendocino with its epicenter at 40 deg 16 deg N., 124 deg 12 deg W., and an original time of 23: 04:46 on May 24, 1958. Travel-time measurements and signal spectra indicate that the nuclear explosions originated within Eniwetok Atoll. The coupling of their signals to the water path apparently was Similar in nature to that of the earthquake T-phase, but the duration of the signals from the nuclear explosions was considerably less.

Levels of cesium-137 ranged betwoen 731 d/m/g dry weight at Kabelle Island, Rongelap Atoll, and 28 d/m/g dry weight at Utirik Island, Utirik Atoll. The average potassium value for all samples
