Abstract

A model for the generation of the strongest earthquakes in subduction regions under conditions of the block structure of the medium is considered. This model represents a significant development of the mathematical keyboard model by L.I. Lobkovsky related to consideration of the discontinuities of not only the frontal but also the rear parts of the island arc. It is shown that the introduction of an additional structural element into the initial model leads to a more accurate assessment of a number of characteristics of the seismic process, since the approach proposed allows taking into account a wider range of geodynamic processes occurring in subduction zones at different stages of the seismic cycle, with the possibility of direct comparison of the theoretical calculations to the satellite geodetic data.

最强俯冲地震的二元键盘模型

摘要

考虑了在介质块状结构条件下俯冲区最强地震的产生模型。该模型代表了李·罗布科夫斯基（LI Lobkovsky）的数学键盘模型的重大发展，不仅考虑了岛弧的前部而且还考虑了后部的不连续性。结果表明，在初始模型中引入额外的结构元素可以对地震过程的许多特征进行更准确的评估，因为所提出的方法允许考虑在俯冲带中发生的更广泛的地球动力学过程。在地震周期的不同阶段，可以将理论计算结果与卫星大地数据进行直接比较。
