Description:
We present ground motion models for northwestern
Turkey using the aftershocks of the Mw 7.4, 1999
Kocaeli earthquake. We consider 4047 velocity and
acceleration records for each component of motion,
from 528 earthquakes recorded by stations belonging to
regional networks. The ground motion models obtained
provide peak ground velocity, peak ground acceleration, and
spectral accelerations for 8 different frequencies between
1 and 10 Hz. The analysis of the error distribution shows
that the record-to-record component of variance is the
largest contribution to the standard deviation of the
calibrated ground- motion models. Furthermore, a clear
dependence of inter-event error on stress drop is observed.
The empirical ground-motion prediction equations, derived
for both the larger horizontal and vertical components, are
valid in the local magnitude range from 0.5 to 5.9, and for
hypocentral distances up to 190 km. Citation: Bindi, D.,
