predicted ground motions for interface earthquakes in the makran subduction zone based on a stochastic finite-fault model

Studies concerned with estimating earthquake hazard analysis require the prediction of strong ground motion. it is well known that some of the larger uncertainties in earthquake hazard analysis are caused by uncertainties in seismic wave attenuation. predictive attenuation relationships have been developed for peak ground acceleration based on simulatedrecords for makran subduction interface. a suite of ground motions has been simulated for a range of magnitude and distances based on the stochastic finite fault ground-motion model (motazedian and atkinson, 2005). the theoretical attenuation relationship, which has been developed for the peak ground acceleration and spectral acceleration, is applicable to earthquakes of mw 7.5 to 9 at a distance up to 200 km.
