Abstract
We employ a realistic finite-extent “k −2 ” stochastic source model with k-dependent rise time, introduced by Bernard et al. (1996) and extended by Gallovic and Brokesova (2004), to synthesize the strong ground motions in near source distances. For a given magnitude, this rupture model involves a number of free parameters (fault dimensions, slip roughness, maximum rise time, slip velocity function). We study their influence on the peak ground acceleration (PGA) maps (parametric study) for an example of the 1999 Athens earthquake of Mw = 5.9. The observed macroseismic intensities serve us as a rough constraint on the simulated PGA’s to find a set of suitable k −2 models. These
