Over 15 years later, Rampino and Haggerty fancifully re-named Napier and Clube's Theory of Terrestrial Catstrophism after Shiva, the Hindu god of destruction. Though Rampino and Haggerty do not reference Napier and Clube's original 1979 article in Nature Magazine, they do reference Clube and Napier's later paper which demonstrates the requisite gravitational forces. Certainly Rampino was aware of Napier and Clube's much earlier publication, as Rampino and Stothers' letter to Nature Magazine in 1984 references it.
