Abstract

This paper is devoted to the problem of identifying seismic generation zones in Fennoscandia. For this purpose, structural-geomorphological interpretation, seismicity analysis, and computer modeling were performed. Based on the results of structural-geomorphological interpretation, the territory was divided into six large blocks. The computer modeling data showed that each of these blocks is characterized by a certain type of stress state in recent times, which thus allowed us to calculate the probability of the formation of new small-scale faults. The reliability of the constructed model is shown by the established numerical correlation between this parameter and the density of earthquake epicenters. A map of seismic generation zones of Fennoscandia was developed based on the data on the density of earthquake epicenters and areas of the possible development of new faults.

利用地震活动性分析和新地球动力学计算机建模识别地震发生区

摘要

本文致力于研究 Fennoscandia 地震发生区的识别问题。为此，进行了构造地貌解释、地震活动性分析和计算机建模。根据构造地貌解释的结果，该领土被划分为六个大块。计算机建模数据表明，这些区块中的每一个都具有近期某种类型的应力状态，从而使我们能够计算新的小规模断层形成的概率。该参数与地震震中密度之间建立的数值相关性表明了所构建模型的可靠性。
