Regional Differences in the Phase Velocity and the Quality Factor Q of Mantle Rayleigh Waves

The phase velocity and the quality factor (Q) of mantle Rayleigh waves from the great Kurile Islands earthquake of 1963 have a close azimuthal correlation with each other and differ considerably among different paths. Serious error may be introduced in the interpretation of observed regionality in phase velocity if regional differences in Q are ignored.
