U.ing .everal well behaved empirical attenuation relations for peak ground acceleration (PGA), developed by various investigators for different parts of the world, an integrated relationship has been developed to normalize for the effects of regional variations in the attenuation characteristics. Simple source-mechanism considerations have been applied to suitably modify the integrated PGA attenuation relationship to get realistic estimat .. of the peak acceleration values at near-field distances. For a case where site specific relation is not available, the presented relationship would provid. more stable and least biased value of peak acceleration compared to that obtained from an arbitrarily chosen relationship for another region.
