"This article has two purposes. Firstly, a validation exercise of the modal summation technique for the computation of synthetic strong-motion records is performed for two regions of Europe\n(Umbria-Marche and south Iceland), using a variety of region specific crustal structure models, by\ncomparing the predicted ground motion amplitudes with observed motions. It is found that the rate of\ndecay of ground motions is well predicted by the theoretical decay curves but that the absolute size\nof the ground motions is underpredicted by the synthetic time-histories. This is thought to be due to\nthe presence of low-velocity surface layers that amplify the ground motions but are not included in\nthe crustal structure models used to compute the synthetic time-histories.\nSecondly, a new distance metric based on the computed theoretical decay curves is introduced\nwhich should have the ability to model the complex decay of strong ground motions. The ability\nof this new distance metric to reduce the associated scatter in empirically derived equations for the\nestimation of strong ground motions is tested. It is found that it does not lead to a reduction in the\nscatter but this is thought to be due to the use of crustal structure models that are not accurate or\ndetailed enough for the regions studied."^^ .
