The common features in establish seismic design criteria for buildings, probabilistic seismic hazard analysis requires estimation of ground motion such as peak ground acceleration (PGA). This estimation process needs to use a ground motion prediction equation (GMPE) which provides PGA estimates incorporating a number of earthquake magnitude, distance and other seismic parameters. On the other hand, it is not always easy to assess inside GMPE since they mostly have all reliable parameters of ground motion records to develop a GMPE. Thus, the objective of this paper is to find the suitable existing models four international GMPEs that provide significant estimates at large source-to-site distance evaluated against comprehensive set of PGA compiled. The dataset of 41 observations of earthquake ground motions recorded provided by Malaysian Meteorological Department (MMD) specifically considered from earthquake with magnitude MW 2.9 to 7.3, fault distance from 10 to 1350 km were plotted and compared to the field records. It was found that the best fitting model of prediction equation proposed by Fukushima and Tanaka (1990) suitable for magnitude 5.0 and above whereas Atkinson and Boore (1997) and Campbell (2003) are suitable for magnitude less than 5.0.
