“…At least part of this problem of dilatational onsets is that P and PcP waves from nuclear explosions normally begin as weak or barely noticeable compressions followed by a strong dilatation (Carder & Bailey 1958;Kogan 1972). In some instances, the PcP onset may be indistinguishable from the background of preceding oscillations.…”

Backus-Gilbert inversions of a new differential PcP data set result in estimates of the core radius, 3484-3486 km, compatible with those obtained from the inversion of large sets of normal mode data. For that part of the core sampled by the data, undulations in the core-mantle boundary can be of order no more than 5-10 km, in the worst possible case.Signal misidentification and lateral inhomogeneities in the upper mantle must be accounted for in observed short-period differential PcP travel times. In the case of Amchitka data, seismic ray tracing is used to describe the effects of a dipping lithospheric plate beneath the Island.

“…Burke-Ga#ney and Bullen [1958] have made important studies. of earlier explosions in the Pacific using records from Riverview and Brisbane as well as stations in other countries.. Carder and Bailey [1958] and Kogan [1960] have made further studies using large numbers of recordings from permanent and temporary stations. Griggs and Press [1961] ha.ve given a list of 169 United States nuclear blasts up to 1958, with their po.sitions and firing times, for the information of seismologists.…”

Travel times from the 1958 series of nuclear explosions near Bikini and Eniwetok islands to Australian seismic stations were studied. For stations at distances between 25 ø and 63 ø the mean residual for P from the Jeffreys-Bullen times for a surface focus was --1.6 __+ 0.7 sec, agreeing with travel-time determinations to other continents. Times to Rabaul (19 ø and 21 ø) strongly suggest a sharp bend in the P curve near 17 ø, corresponding to the '20 ø discontinuity.' There is also a possible bend near 25 ø to 26 ø, but this would be less marked. 1115 1116 DOYLE AND WEBB

“…evaluated the travel times from Pacific sources, including the extensive data from the studies of Carder and Bailey (1958) and Kogan (1960). Early P-wave arrivals were noted at continental stations, confirming Gutenberg and Richter's results.…”
