摘要滑移率、锁定宽度和地震动预测方程的选择在地震危险性分析中是非常重要的，因为它们可以用来估计地震的重现性、限制震源的最大震级和估计地震地面震动。在这项研究中，我们研究的灵敏度概率地震危险性分析（PSHA）断层滑动速率，断层锁定宽度和选择的GMPEs的亚齐断层段，印度尼西亚。由于这三个参数的变化，危险程度的差异很大。因此，在应用PSHA在高故障参数不确定性的领域需要仔细考虑。
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.
