Abstract	Ground motion models represent empirical mathematical-physical models of ground motion under strong earthquakes defined on the basis of databanks of past earthquake records. Within these, the ground motion parameters as dependant random variables are related to the earthquake parameters, the seismic energy transfer characteristics of the region through which the seismic waves propagate and the influence of the local soil conditions as independent random variables. Regression analysis, either single or double, can be applied as a method for their determination. They are used in deterministic and probabilistic methods for prediction and estimation of the expected seismic action of future earthquakes upon the investigated location or region.Ground motion models are very important for prediction of future seismic actions and have been paid special attention. Following the analysis of a variety of published ground motion models for shallow and subduction earthquakes carried out by different authors, there are predictive equations, methods, synthesis, discussions on the state of the art and new trends in investigations of ground motion models.In this study, the author’s attention has been focused on the new ground motion model dependant on the azimuth, which the author has developed and applied for determination of peak ground acceleration attenuation laws for the Vrancea intermediate earthquakes (Stamatovska 1996, 2002, 2006, Stamatovska and Petrovski 1997). Besides the already published results for the peak ground acceleration attenuation laws-PGA for the locations Bucharest, Cherna Voda, and Valeni, the author presents, for the first time, the progress of the applied ground motion model dependent on azimuth in determination of the response spectrum attenuation laws for the Vrancea intermediate earthquakes for Cherna Voda and Bucharest locations.
