The effect of attenuation on the spectra of P waves from nuclear explosions in North America. Technical report

Technical Report ·
OSTI ID:7323087
Anelastic attenuation (t star) was measured along various paths in North America using spectra of P-waves from nuclear explosions PILEDRIVER, KNICKERBOCKER, MAST, GNOME, and SALMON to various LRSM and SDCS stations. The results are consistent with the presence of a sizeable low Q layer under the western United States (WUS) and the absence of such layer under the tectonically stable eastern part of North America. Typical values of (t star) at intermediate distances along paths crossing this low-Q layer are around .45. Paths outside WUS have typical (t star) values around .15. (GRA)
