地下结构建模的难度是定量研究地震现象的瓶颈。考虑到建模的不确定性，随机建模是一种选择，作者一直在为随机模型开发两种分析方法。本文统一介绍了这些方法，强调了数值计算的效率。以地震波传播和地表地震断层形成为例进行了求解，并将计算结果与观测数据进行了比较，验证了随机模型分析方法的有效性和局限性。
The difficulty of modeling underground structures is a bottleneck in quantitatively studying earthquake phenomena. Stochastic modeling that accounts for the uncertainty of modeling is an alternative, and the authors have been developing two analysis methods for a stochastic model. This paper presents these methods in a unified manner, emphasizing the efficiency of numerical computation. The earthquake wave propagation and the surface earthquake fault formation are solved as examples, and the results are compared with observed data to examine the validity and limitation of the analysis methods of the stochastic model.
