Analysis of the Origins of κ (Kappa) to Compute Hard Rock to Rock Adjustment Factors for GMPEs
TL;DR: In this paper, an inversion scheme is used to separate site, source, and path contributions to ground-motion recordings, and the site component of κ ( κ ), estimated at the surface and the depth, with different S-wave velocity measures and with the fundamental resonant frequency of the site.
Journal ArticleDOI
Taxonomy of κ: A Review of Definitions and Estimation Approaches Targeted to Applications
TL;DR: In this article, the authors discuss the use of κ0 in various engineering seismology applications today and why interest in this parameter has been revived, briefly discuss its possible physical interpretations, and detail the known approaches to estimate κ 0 from seismic records.

Attenuation of seismic shear wave energy in Switzerland
TL;DR: In this article, the Fourier spectral amplitude of small-to-moderate earthquakes, recorded on the local seismic networks, is modeled by Q and κ, while apparent geometrical spreading models account for the frequency-independent decay of energy.

vS30, κ, regional attenuation and Mw from accelerograms: application to magnitude 3–5 French earthquakes
TL;DR: In this paper, the authors investigated recordings from weak to moderate earthquakes, with magnitudes ranging between about 3 and 5, recorded by the French Accelerometric Network, for the events with magnitude greater than 3 that occurred between 1996 and 2006.

A Study on the Variability of Kappa (κ) in a Borehole: Implications of the Computation Process
TL;DR: In this article, the effect of soil conditions on the acceleration spectral shape was investigated in a vertical array consisting of more than two stations in a downhole array with five stations in soils and rock.

A model for the shape of the fourier amplitude spectrum of acceleration at high frequencies
John G. Anderson,Susan E. Hough +1 more
TL;DR: In this paper, the spectral decay parameter k shows little variation at a single station for multiple earthquakes at the same distances, but it increases gradually as the epicentral distance increases.
