On Yields of May 11, 1998 Indian explosions by network averaged teleseismic P-wave spectra

Abstract: We show here that the network averaged teleseismic P-wave spectra for Indian explosions of May 11, 1998, given by Barker et al, do not have an unambiguous interpretation. Barker et al had earlier demonstrated these were similar to the Shagan River testing site of former Soviet Union. We prove here that these are equally consistent with RUBIS (57 kt) and PILEDRIVER (62kt) explosions in French Hogger and US Nevada testing sites respectively.

The above analysis clearly shows that the net work-averaged P wave spectra given by the US scientists now fully support the radiochemical yield estimates of Indian scientists and also the interpretation of close-in data and seismic analysis done earlier (Sikka et al [7- 9] and Roy et al [10]) and that the thermonuclear device performed as designed (see Table 1).
