Prediction of Horizontal Response Spectra in Europe

A large and uniform dataset is used to find equations for the prediction of absolute spectral acceleration ordinates in Europe and adjacent areas, in terms of magnitude, source-distance and site geology. The dataset used is shown to be representative of European strong motion in terms of the attenuation of peak ground acceleration. The equations are recommended for use in the range of magnitudes from MS 4⋅0 to 7⋅5 and for source-distances of up to 200 km.
