The final model, for which point source responses are calculated by a discrete wavenumber/finite element technique, uses a structure with gradients in material properties rather than layers. The 1979 Imperial Valley earthquake triggered all of the accelerographs within about 100 km of the epicenter, and one as far away as 196 km. Several accelerograms were recorded in the vicinity of a steam power plant and near a tank farm where some tanks suffered structural damage.
