The prediction of ground motion from large future earthquakes is important for hazard mitigation in urban areas. The ground motions are affected by three factors: the seismic source, crustal attenuation (quality factor) of seismic waves inside the heterogeneous earth, and the near-surface effects of local site conditions. Understanding each of these factors is essential for ground motion prediction.Subjects--Topical Terms:

520 $a The prediction of ground motion from large future earthquakes is important for hazard mitigation in urban areas. The ground motions are affected by three factors: the seismic source, crustal attenuation (quality factor) of seismic waves inside the heterogeneous earth, and the near-surface effects of local site conditions. Understanding each of these factors is essential for ground motion prediction.
520 $a In this study, ground motions are calculated by modeling these three effects. A kinematic model is used for the earthquake source. A multi-layered velocity and attenuation structure is used to model crustal propagation effects. These two effects are accounted for through forward modeling. The local site effects are derived by inverting data from small (MW &sim; 4-5) earthquakes. Site effects are usually estimated relative to the ground motion at a reference station, usually a rock site. In such cases the site effects are always dependent on the choice of a reference site. In order to avoid this problem, a method is developed to estimate "absolute" site effects---the response relative to the seismological basement (usually corresponding to the layer VS 3.0 km/s). After site responses are derived for an array of strong motion stations, these site responses are used to predict the site response at locations for which there are no observed records. This new approach for modeling and predicting ground motion is validated against independent data. The source, path and site response are combined to predict spectral amplitudes of ground motion within and around Sendai from future earthquakes that may occur in northeastern Japan.
