A methodology for the updating of stochastic models for the description of seismic ground motions recorded over extended areas is presented. The approach (i) embeds seismic ground motion parameter estimation in a probabilistic framework; (ii) identifies temporal and spatial seismic ground motion characteristics simultaneously; and (iii) eliminates the requirement of spectral smoothing in coherency evaluations from recorded data. Thus, it provides more reliable estimates for seismic ground motion characterization than current practice; such estimates are necessary in the seismic response evaluation of lifelines.
