As we will discuss below, the precise number of devices the Indians and Pakistanis may have used and the precise number that were detonated is unclear.
More information is needed to accurately determine what transpired.
Questions about Indian tests. India first tested a device on May 18, 1974. Initially the Bhabha Atomic Research Center claimed the explosive yield of the test was 12 kilotons. Later they reduced their estimate to eight kilotons. The magnitude of the seismic waves from the 1974 test, when combined with its announced depth and the formation of a subsidence crater at the surface, strongly suggested that the actual yield was less than five kilotons.
