我们试图在对可能发生地震的断层进行地质调查和对震源模型进行地震学研究的基础上，制定出一种预测地面运动的方法。通过对活动断层的分段和分组、孕震区断层宽度和震源区与震源经验关系中的活动断层的地震矩的测量，估算了假想地震的断层总长度。基于15次地壳地震震源反演统计分析的断层面滑动不均匀性标度关系。我们基于满足断层表面滑动不均匀性的自相似凸体分布及其k平方模型的二维傅里叶变换进行震源模拟。
We attempted to make a recipe for the prediction of ground motions, based on geological investigations of capable earthquake faults and seismological studies of source models. Total fault lengths of scenario earthquake are evaluated from survey of segmentation and grouping of active faults, fault widths from seismogenic zones, and seismic moment of the capable faults from the empirical relationship between the source areas and seismic source. The scaling relations of slip heterogeneity on fault plane based on a statistical analysis of the source inversion of fifteen crustal earthquakes. We made source modeling based on a self-similar distribution of asperities satisfying the heterogeneity of slip on the fault surface and its two-dimensional Fourier transform of the k-squared model.
