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 averageâ€¦ (More)

Predictive relations are developed for ground motions from eastern North American earthquakes of 4.0 =< M =< 7.25 at distances of 10 =< R =< 500 km. The predicted parameters are response spectra atâ€¦ (More)

A database of 1700 digital seismograms from 186 earthquakes of magnitude mN 2.5â€“5.6 that occurred in southeastern Canada and the northeastern United States from 1990 to 2003 was compiled.â€¦ (More)

Ground-motion relations are developed for California using a stochastic simulation method that exploits the equivalence between finite-fault models and a two-corner point-source model of theâ€¦ (More)

Ground motions from earthquakes are created by ruptures on tectonic faults. The causative faults can be considered point sources at distances large compared to the fault dimensions. At closerâ€¦ (More)

We generalize source, path, and site effects for California earthquakes as functions of magnitude and distance, based on regression analysis of 1000 Fourier acceleration spectra from 43 Californiaâ€¦ (More)

The high-frequency seismic field near the epicenter of a large earthquake is modeled by subdividing the fault plane into subelements and summing their contributions at the observation point. Eachâ€¦ (More)

The ground motion from large earthquakes is often predicted based on finite-fault modeling, in which the fault plane is discretized into small independently rupturing subfaults; the radiation fromâ€¦ (More)

Ground-motion models based on the Bmne point-source approximation have an underlying 092 spectrum, with a single comer frequency. These models overpredict observed spectral amplitudes at low toâ€¦ (More)

The high-frequency shape of the earthquake spectrum strongly influences the amplitude of the peak ground acceleration and of the response spectrum at frequencies of 10 Hz and greater. A key parameterâ€¦ (More)
