Eric M. Thompson, Robert E. Kayen, Brad Carkin, Hajime Tanaka
2010, Open-File Report 2010-1168
We present one-dimensional shear-wave velocity (VS) profiles at 52 strong-motion sites that recorded the 28 September 2004 Magnitude 6.0 Parkfield, Calif., earthquake. We estimate the VS profiles with the Spectral Analysis of Surface-Waves (SASW) method. The SASW method is a noninvasive method that indirectly estimates the VS at depth from variations in the Rayleigh...
