Ground-Motion Prediction Equations for the Average Horizontal Component of PGA, PGV, and 5%-Damped PSA at Spectral Periods between 0.01sand 10.0s

Abstract

This paper contains ground-motion prediction equations (GMPEs) for average horizontal-component ground motions as a function of earthquake magnitude, distance from source to site, local average shear-wave velocity, and fault type. Our equations are for peak ground acceleration (PGA), peak ground velocity (PGV), and 5%-damped pseudo-absolute-acceleration spectra (PSA) at periods between 0.01 s and 10 s. They were derived by empirical regression of an extensive strong-motion database compiled by the “PEER NGA” (Pacific Earthquake Engineering Research Center's Next Generation Attenuation) project. For periods less than 1 s, the analysis used 1,574 records from 58 mainshocks in the distance range from 0 km to 400 km (the number of available data decreased as period increased). The primary predictor variables are moment magnitude ( M), closest horizontal distance to the surface projection of the fault plane ( RJB), and the time-averaged shear-wave velocity from the surface to 30 m ( VS30). The equations are applicable for M=5–8, RJB<200 km, and VS30=180–1300 m/s.

High-frequency filtering of strong-motion records

“…Note that the processing information given in the "Reason" column does not imply that the authors of the GMPE did the processing; in fact, most of the GMPEs used data processed by others. Only GMPEs by Zhao et al (2006) and Boore and Atkinson (2008) in this list were derived using a large number records from digital instruments (the other GMPEs are overwhelmingly based on records from analogue instruments). .…”

Evaluating the Post-Earthquake Accessibility of Hospitals for Mitigation Strategy Decision Support by Fragility and Connectivity Modelling

“…This MCE was attributed with a moment magnitude of 6.9. Other characteristics were unspecified, but not required to calculate peak ground acceleration (PGA) using the selected ground-motion prediction equation (GMPE) developed by Boore & Atkinson [13], which was appropriate for the shallow crustal environment in California. The GMPE also required input values for Vs 30 , the average shear-wave velocity to 30m depth, which were obtained from the USGS Global Vs 30 Map Server [14].…”

On the Sensitivity of Ground Motion Prediction Equations in Greece

“…In equation (2) the terms f1 STS, f2 SFS representing a linear amplification model had been replaced by a function f (M,R,Vs30) predicting linear and non-linear amplification factors. To calculate linear and non-linear amplification terms we followed the methodology introduced by Boore and Atkinson (2008) as part of the Next Generation Attenuation project of Pacific Earthquake Engineering Research Institute. Spectral amplification coefficients proposed in Boore and Atkinson (2008) were considered to be an improvement of the ones suggested in Choi and Stewart (2005) and they have been further used in this research study.…”
