Abstract Based on an analysis of seismicity for the period of 1900–2018, the seismic potential of the Kuril–Kamchatka subduction zone is estimated, and the geometry of interplate coupling of the North American and Pacific lithospheric plates and the rate of seismic underthrusting of the latter beneath the former are specified. In order to identify areas of modern seismic deficits in the subduction zone, an approach based on the cumulative displacement of interplate earthquakes with M w ≥ 7.0 is proposed. Together with other methods, such an approach contributes to a more accurate seismic hazard assessment of the region.

千岛-堪察加俯冲带的当代地震赤字

摘要 基于 1900-2018 年地震活动性分析，估计了千岛-堪察加俯冲带的地震潜力，以及北美和太平洋岩石圈板块的板间耦合几何形状和地震下推率。后者在前者之下被指定。为了识别俯冲带现代地震缺陷区，提出了一种基于 M w ≥ 7.0 的板间地震累积位移的方法。与其他方法一起，这种方法有助于对该地区进行更准确的地震危险性评估。
