Abstract

This article presents a stochastic ground-motion accelerogram model for Northwest Europe which simulates accelerograms compatible with seismic scenarios defined by earthquake magnitudes 4 <Mw <6.5, distance-to-site 10km <Repi <100km and different types of soil (rock, stiff and soft soil). This model is developed based on Rezaeian and DerKiureghian (2008,2010) [1,2] and is a set of pre- dictive equations that define a time-modulated filtered white-noise process. Such predictive equations were calibrated by means of the random-effects regression technique using a subset of the European database of accelerograms.The model is validated in terms of PGA, PGV and spectral accelerations using GMPEs for the UK, Europe and Middle East, and other Stable Continental Regions. This model is the first of its kind for NW Europe.
