Spectral Ratios for Explosions in Salt
Abstract
Comparison of the P-wave spectra at common stations from the events GNOME, SALMON, and three nuclear tests in salt in the USSR shows that amplitudes are greatly enhanced by shallow burial. The scaling theory of Mueller and Murphy partially accounts for the enhancement, but there remain major differences between theory and observation, particularly at frequencies above 1 Hz. If material properties of salt at the different sites are different then that, and not the depth, may have caused the difference. Effects of pp, consistent with a reflection coefficient of approximately 0.5, can be seen in the spectral ratios.
