    Abstract

    Slip rate, locking width and ground-motion prediction equation (GMPE) selection are important in seismic hazard analysis because they are used to estimate earthquake recurrence, to limit the maximum magnitude in an earthquake source and to estimate earthquake ground shaking. In this study, we examine the sensitivity of probabilistic seismic hazard analysis (PSHA) to fault slip rates, fault locking width and the selection of GMPEs for the Aceh Fault Segment, Indonesia. The hazard level differences vary considerably owing to changes in these three parameters. Therefore, careful consideration is needed in applying PSHA in areas of high fault parameter uncertainty.
