To estimate the hazard posed by active faults, estimates of the maximum magnitude earthquake that could occur on the fault are needed. I compare previously published scaling relationships between earthquake magnitude and rupture length with data from recent earthquakes in Indonesia. I compile a total amount of 13 literatures on investigating coseismic deformation in Indonesia, which then divided into strike‐slip and dip‐slip earthquake cases. I demonstrate that a different scaling relationship generates different misfit compared to data. For a practical practice of making seismic hazard model in Indonesia, this research shows the suggested reference for a scaling relationship of strike‐slip and dip‐slip faulting regime. On a practical approach in constructing a logic tree for seismic hazard model, using different weighting between each published earthquake scaling relationship is recommended.

印度尼西亚地壳地震的地震标度关系评估

为了估计活动断层造成的危害,需要估计断层上可能发生的最大地震。我将先前公布的地震震级和破裂长度之间的比例关系与印度尼西亚最近地震的数据进行了比较。整理了13篇有关印度尼西亚同震变形研究的文献,将其分为走滑和倾滑地震案例。我证明了与数据相比,不同的缩放关系会产生不同的失配。对于印度尼西亚地震灾害模型的实际制作,本研究为走滑和倾滑断层体系的标度关系提供了建议参考。关于构建地震灾害模型逻辑树的实用方法,
