Source Time Functions and Spectra for Underground Nuclear Explosions

Abstract

The model of Haskell for explosion source time functions and spectra fails to satisfy data in the short-period band recorded teleismically from the three Amchitka Island underground nuclear tests: LONG SHOT, MILROW and CANNIKAN. A more recent model due to Mueller and Murphy satisfies the data quite well. The difference in the two models is basically in the falloff at high frequencies. A simple revision of Haskell's model produces waveforms and spectra nearly identical to ones from Mueller and Murphy's model. This revision requires velocity waveforms to have a rise time of extremely short duration at the elastic boundary, a premise validated by actual near-field measurements.
