摘要本研究试图提出一种新的模拟模型，能够产生综合的随机地震场景，包括地震学，加速度信号的属性。由于伊朗高原有高质量的地震数据库，因此被选为开发模型的大陆。该模型由两个子模型组成。第一个生成随机地震事件的场景，包括主震和余震。第二个产生的三维合成随机加速度为每个先前模拟的事件。这种基于ARMIO的预测模型提供了一个强大的工具，风险建模者有兴趣在终身地震风险评估，通过更现实的地震场景。
ABSTRACT This research attempts to propose a new simulating model capable of generating synthetic stochastic earthquake scenario including both seismological, and acceleration signal properties. The Iranian plateau is selected as a mainland for developing the model due to the existence of high-quality earthquake databases. This model is composed of two sub-models. The first one generates random seismic event scenarios including mainshocks and aftershocks. The second one procreates 3-dimensional synthetic stochastic accelerograms for each of the previously simulated events. This scenario-based predictive model offers a powerful tool to the risk modelers interested in lifetime seismic risk assessment through more realistic earthquake scenarios.
