Abstract

Ground-motion attenuation models have been derived for the Australian crust. These models employ both empirical and stochastic methods and are the first spectral groundmotion models to be based entirely on Australian ground-motion data. Two key datasets have been employed to derive empirical ground-motion attenuation models for Australia; one from data recorded in the Palaeozoic crust of southeastern Australia (SEA) and the other from the Archean shield region of southwestern Western Australia (WA). Empirical ground-motion models are derived for each of these datasets. In general, low-frequency (e.g. 1 Hz) ground-motion energy appears to attenuate less in WA than in SEA. These empirical models suggest that SEA has similar near-source attenuation with eastern North America.
