Ground Motion Prediction Methodologies for Eastern North America by Apostolos
The objectives of this task are both to conduct research on seismic hazards, and to provide relevant input on the expected levels of these hazards to other tasks. Other tasks requiring this input include those dealing with inventory, fragility curves, rehabilitation strategies and demonstration projects. The corresponding input is provided in various formats depending on the intended use: eithe...

متن کاملGround-Motion Prediction Equations for Eastern North America from a Referenced Empirical Approach: Implications for Epistemic Uncertainty
I outline a referenced empirical approach to the development of groundmotion prediction equations (GMPEs). The technique is illustrated by using it to develop GMPEs for eastern North America (ENA). The approach combines the ENA ground-motion database with the empirical prediction equations of Boore and Atkinson (2008) for the reference region of western North America (WNA). The referenced empir...
متن کاملGeneric Finite-Fault Model for Ground-Motion Prediction in Eastern North America
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 to intermediate frequencies ( -0 .1 to 2 Hz), for earthquakes with moment magnitudes M of 4 or greater. The empirical spectra of moderate to large events tend to sag at these frequencies, relative to the le...
متن کاملPrediction of Strong Ground Motion Using the Hybrid Empirical Method and Its Use in the Development of Ground-Motion (Attenuation) Relations in Eastern North America
Ground-motion (attenuation) relations are used to estimate strong ground motion for many engineering and seismological applications. Where strongmotion recordings are abundant, these relations are developed empirically from strong-motion recordings. Where recordings are limited, they are often developed from seismological models using stochastic and theoretical methods. However, there is a larg...
