In this study, local tsunami hazard due to seismic sources is evaluated in a stochastic framework. Several assumptions such as static passive generation, constant rake angle and source centroid (among others) are relaxed. Spatial uncertainties are modeled in a large set of scenarios. The proposed methodology is easy to implement and can be combined with other types of sources or hazards. Application in the Kuril-Kamchatkah trench shows a straightforward use of our methodology, producing simple hazard maps, which can be replicated in any region of the world.
在这项研究中,我们在随机框架下评估了地震源引起的局部海啸灾害。我们放宽了一些假设,如静态被动产生、恒定的滑动角和震源中心(等等)。在大量场景中对空间不确定性进行建模。所提出的方法易于实现,并且可以与其他类型的源或危害结合使用。在千岛-堪察加海沟的应用表明,我们的方法使用简单,生成简单的灾害图,可以在世界任何地区复制。
