Abstract

The paper presents seismological, forecasting, and seismotectonic data on the strong March 25, 2020 earthquake in the Northern Kurils. The collected materials on an unusual deep lithospheric earthquake in the border area of the Northern Kurils and Southern Kamchatka made it possible to understand the structure of the source of this event, as well as to determine the features of the seismic process in it. The variability of release of the scalar seismic moment (M₀) made it possible to trace the seismic history over the past 110 years in the preparation zone of the March 25 earthquake. The dynamics of development of the aftershock process in terms of the release of M₀ was also studied.

摘要

本文介绍了2020年3月25日北部千岛群岛强烈地震的地震学，预测和地震构造数据。在北部千岛群岛和堪察加半岛南部边界地区发生的一次异常的深部岩石圈地震中，收集到的资料使人们有可能了解该事件的来源结构，并确定其中地震过程的特征。标量地震矩（M ₀）释放的变化性使得追踪3月25日地震准备区过去110年的地震历史成为可能。还研究了M ₀释放后余震过程发展的动力学。
