In Frankel et al.
(1999), we incorrectly
described part of the shear-wave velocity (Vs) profile
used to calculate the predicted spectra at site KD1 near the Kingdome in
Seattle (figure 7 of Frankel et
al., 1999). The shear-wave velocity profile we used was
partially determined from a seismic refraction/reflection survey reported by
Williams et al. (1999)
at sites KD1 and KD2. The velocity of the stiff deposits underlying the fill
was taken from a borehole measurement at a nearby location
(Shannon and Wilson, unpublished report,
1994). The shear-wave velocity profile consisted of a 19-m-thick
layer of fill and recent alluvium with Vs of 145 m/sec
over a 1.1-km-thick layer of stiff Pleistocene deposits, with
Vs of 579 m/sec over a half-space, with
Vs of 1.0 km/sec (bedrock). The thickness of the top layer
was determined by Williams et al.
(1999) from the timing of a
strong shear-wave reflection observed in their survey and the velocity of the
initial S-wave arrival. This reflection is from the interface between
the overlying artificial fill and the stiff soil unit beneath. As reported in
Williams et al.
(1999), the two-way travel time
observed from the reflection survey (0.265 sec) is consistent with the 2 Hz
resonance observed in the earthquake data by Frankel et al.
(1999). The error in our
description of the profile does not affect the results reported in our
article.
