Ground-motion (attenuation) relations are used to estimate strong ground
motion for many engineering and seismological applications. Where
strong-motion recordings are abundant, these relations are developed
empirically from strong-motion recordings. Where recordings are limited, they
are often developed from seismological models using stochastic and theoretical
methods. However, there is a large degree of uncertainty in calculating
absolute values of ground motion from seismological models in regions where
data are sparse. As an alternative, I propose a hybrid empirical method that
uses the ratio of stochastic or theoretical ground-motion estimates to adjust
empirical ground-motion relations developed for one region to use in another
region. By using empirical models as its basis, the method taps into the vast
amount of observational data and expertise that has been used to develop
empirical ground-motion relations in high-seismic regions such as western
North America (WNA). I present a formal mathematical framework for the hybrid
empirical method and apply it to the development of ground-motion relations
for peak ground acceleration and acceleration response spectra in eastern
North America (ENA) using empirical relations from WNA. The application
accounts for differences in stress drop, source properties, crustal
attenuation, regional crustal structure, and generic-rock site profiles
between the two regions. The resulting hybrid empirical ground-motion
relations are considered to be most appropriate for estimating ground motion
on ENA hard rock with a shear-wave velocity of 2800 m/sec for earthquakes of
MW 
5.0 and rrup 
70 km.
However, it has been extended to larger distances using stochastic
ground-motion estimates so that it can be used in more general engineering
applications such as probabilistic seismic hazard analysis.
