Regionally adjustable generic ground‐motion prediction equation based on equivalent point‐source simulations: Application to central and eastern North America

E Yenier, GM Atkinson - Bulletin of the Seismological …, 2015 - pubs.geoscienceworld.org
We develop a generic ground‐motion prediction equation (GMPE) that can be adjusted for
use in any region by modifying a few key model parameters. The basis of the GMPE is an …

Development of a response spectral ground‐motion prediction equation (GMPE) for seismic‐hazard analysis from empirical Fourier spectral and duration models

SS Bora, F Scherbaum, N Kuehn… - Bulletin of the …, 2015 - pubs.geoscienceworld.org
Empirical ground‐motion prediction equations (GMPE s) require adjustment to make them
appropriate for site‐specific scenarios. However, the process of making such adjustments …

Spectral models for ground motion prediction in the L'Aquila region (central Italy): evidence for stress-drop dependence on magnitude and depth

F Pacor, D Spallarossa, A Oth, L Luzi… - Geophysical Journal …, 2016 - academic.oup.com
In this study we derive a spectral model describing the source, propagation and site
characteristics of S waves recorded in central Italy. To this end, we compile and analyse a …
