Attenuation and scattering of broadband P-italic and S-italic waves across North America
Journal Article

· J. Geophys. Res.; (United States)
Differential attenuation (deltat-italic*) measurements of teleseismic P-italic and S-italic waves are made in the frequency range 0.05--5.0 Hz across North America using broadband seismic data from the Department of Energy's Regional Seismic Test Network and Lawrence Livermore National Laboratory's Basin and Range network. Data from four events have been analyzed by first assuming frequency independent Q-italic. The observed regional variations for (deltat-italic*) are consistent with previous studies and show greater attenuation for stations in the Basin and Range relative to those in shield regions of North America.
