Abstract
Tectonic and seismic activities induce crustal rock fracturing in the immediate surroundings of buried fault discontinuities. The heterogeneous nature of this 3-D scatter distribution leaves a high-frequency footprint on the recorded wave-field at surface. This study represents an attempt to clarify the complex relationship between the propagated wave-field and the statistical properties of the regional medium. This objective is pursued by inspecting the broadband (0-25Hz) synthetic wave-forms obtained by sourceto-site 3-D numerical simulations in regional-size scenarios. The presented numerical study compares the major differences obtained when including heterogeneous properties in the model. Coda-waves are analysed and the high-frequency attenuation is assessed by computing the k coefficient for different source-station configurations.
