Hp. Liu et al., IN-SITU MEASUREMENT OF SEISMIC SHEAR-WAVE ABSORPTION IN THE SAN-FRANCISCO HOLOCENE BAY MUD BY THE PULSE-BROADENING METHOD, Bulletin of the Seismological Society of America, 84(1), 1994, pp. 62-75
By the pulse-broadening method, seismic absorption of San Francisco Ho
locene Bay Mud has been determined with the use of an impulsive shear-
wave source at the surface, two receivers embedded in clay (Holocene B
ay Mud), and digital seismic recording. The seismic anelastic quality
factor is determined from 20 measurements to be 16.0 with a random err
or of +/- 0.9. Three sources of systematic error are examined. The fra
ctional systematic error on the anelastic quality factor is estimated
to be approximately 11 %. Details of experimental arrangement and erro
r analysis are given.
