摘要

It shouldbe clear to the general reader of the papers on the seismological estimation of the yield of the Indian nuclear tests of 1998 that these estimates are subject to large uncertainties- which is one of the purposes of our paper. Despite what Sikka et al. seem to believe, we set out to see what seismological evidence there is that the yield of 980511 is above about 20 kt, the upper bound of most non-Indian estimates and we hope we have given a fair assessment of the evidence. We are the only group outside India to make a plausible argument that the yield of 980511 could have been significantly greater than 20 kt. Sikka et al. claim we should have pointed out that the range of estimates extends up to 110 kt, they do not however, point out that by the same argument it extends down to 22 kt. We do not wish to comment on the minutiae of the argument of Sikka et al. on magnitude differences. If such an involved argument is required to arrive at a seismological estimate of yield, the estimate cannot be regarded as robust. Sikka et al. ask for, amongst other things, fuller explanations of our interpretation of M_s, and of how we reached the conclusion that the effects on mb of interference between P from the two largest explosions of 980511 are negligible. This we are happy to do, but this will take more time and journal space than we have been allowed for this reply. We therefore intend to deal with the request of Sikka et al. in a later paper. Perhaps however, we should emphasize that the Ms values reported by the NEIS (and used apparently by Evernden) are measured from earthquake signals which are mistakenly associated with 980511.
