摘要

根据时间和地理位置的不同，地震资料的收集或多或少是详尽和系统的。因此，地震目录包含一些孤立的地震事件。这些信息通常被排除在递归模型的推理过程之外。在本文中，我们假设地震是在古腾堡-里希特假设下用平稳泊松点过程来模拟的。我们提出了一种通过调整泊松点过程的似然表达式来考虑这些信息的方法。此外，我们考虑完备性的大小随时间而变化。

Estimation of the Gutenberg-Richter Seismic Hazard Parameters: A Way to Take into Account Isolated Earthquakes—Application to the Alps Domain

Depending on the time period and geographical location, the collection of seismic data has been more or less exhaustive and systematic. Thus, seismic catalogues contain some isolated seismic events. This information is usually excluded from the inference process of the recurrence model. In this paper, we assume that earthquakes are modelled by a stationary Poisson point process, under the Gutenberg-Richter assumption. We propose a way to take that information into account by adapting the expression of the likelihood of the Poisson point process. In addition, we consider that the completeness magnitude varies in time.
