Recent seismological studies have focused on the understanding and characterization of strong ground motion in the near field. The effect of near-field motions on structures has been observed from past earthquakes to be particularly important; however, systematic studies of these effects had not been conducted so they now are a focus of current research.

The resulting ground motion time histories, the associated acceleration and displacement response spectra at various distances from the fault as well as the spatial distribution of spectral response amplitudes at large discrete periods (2 to 10 sec) are studied for the characterization of long period ground motion and structural response in terms of fault normal, fault parallel and mean components.
