In a way perhaps not dissimilar to stress drop (Atkinson and Beresnev, 1997), the high-
frequency attenuation parameter κ (kappa), introduced by Anderson and Hough (1984), is …

Seismic attenuation and the associated quality factor (Q) have long been studied in various
sub-disciplines of seismology, ranging from observational and engineering seismology to …

The observable decay with frequency (f) of Fourier amplitude spectra for ground-motion
recordings is controlled by a parameter κ: exp (-πκf). We analyze data from the KiK-net …

Ground‐motion models for response spectral ordinates commonly partition site‐response
effects into linear and nonlinear components. The nonlinear components depend upon the …

Abstract Knowledge of the acceleration spectral shape is crucial to various applications in
engineering seismology. Spectral amplitude decays rapidly at high frequencies. introduced …

At high frequencies, the acceleration spectral amplitude decreases rapidly; this has been
modelled with the spectral decay factor κ. Its site component, κ 0, is used widely today in …

A ground‐motion prediction equation (GMPE) specific to rock and stiff‐soil sites is derived
using seismic motion recorded on high VS 30 sites in Japan. This GMPE applies to events …

The reference rock site condition has two important applications for ground‐motion
prediction in the stable continental region of central and eastern North America (CENA).(1) It …

Modelling the attenuation of shear wave energy is an important component of seismic
hazard analysis. Previous studies have shown how attenuation, particularly in the …

We investigate recordings from weak to moderate earthquakes, with magnitudes ranging
between about 3 and 5, recorded by the French Accelerometric Network. S-wave spectra are …
