Ground motion prediction equation (GMPE) is an important component for seismic hazard study to minimize the casualty from an earthquake, especially in the building collapse. This study presents ground motion prediction equation for West Sumatra due to distant shallow crustal, interface, and intraslab earthquakes. The data sets consist of 375 strong motion data that are recorded by Meteorological, Climatological, and Geophysical Agency’s (BMKG) accelerograph sensors that located in West Sumatra, earthquake parameter data are from BMKG’s earthquakes catalog with the range moment magnitude of 4.0-6.4 and recorded at sites with hypocentral distance of 17 – 1000 km, focal mechanism data are from Global Centroid Moment Tensor (GCMT), and use site classification to enhance the quality of the results. This study shows good results with the standard deviation of residual value of 0.23 for shallow crustal, 0.29 for interface, and 0.49 for intraslab earthquakes.
