The values of
3 listed in table 1 of Pankow and
Pechmann (2004) are too large by
a factor of
2 because they were calculated using equation (3) of Boore
et al. (1993), which has
an error in it as reported by Boore
(2005) and Spudich and Boore
(2005). The
3 for the peak ground velocity (PGV) should be
changed from 0.106 to 0.075. The rest of the
3 values
are originally from table 2 of Spudich et al.
(1999), and their corrections are
discussed in Spudich and Boore
(2005). The
3 values are needed for calculating the standard
deviation of the ground-motion prediction for a randomly oriented horizontal
component. The results for the horizontal-component geometric mean are
unaffected by the error.
