Abstract

This paper is concerned with the influence of the large (M_L = 6.9) 2021 Hubsugul earthquake on the seismicity of the block structure in the junction area between the Altai–Sayan mountain region and the Baikal Rift Zone. This study uses data from the networks of seismic stations operated by the Altai–Sayan and Baikal branches of the RAS Geophysical Survey, as well as from Mongolian stations. We show the evolution of the seismic process near the boundaries of the Tuva–Mongolia block and adjacent blocks in eastern Tuva. We have determined and studied the source zone of the Darkhad earthquake swarm which was formed in 2022‒2023 as several sequences of events, with the larger ones having magnitudes M_L > 5. Simultaneously with the activation of the Hubsugul earthquake source zone, we observed high seismic activity in the source zones of past large earthuuakes: 1991 Busingol, 2011‒2012 Tuva events, and 2008 Belin-Bii-Kham. The action of the Hubsugul earthquake on the seismicity in boundary blocks of the Altai–Sayan and Baikal zones was different from that of the 2003 Chuya earthquake on Altai seismicity.

2021年呼素古尔地震对阿尔泰-萨彦山与贝加尔湖裂谷交界处地震活动性的影响

本文研究了2021年（ML = 6.9） Hubsugul大地震对阿尔泰-萨延山区与贝加尔湖裂谷带交界处地块构造地震活动性的影响。本研究使用的数据来自RAS地球物理调查的阿尔泰-萨扬和贝加尔湖分站运营的地震台站网络，以及蒙古台站的数据。在图瓦东部靠近图瓦-蒙古块体边界和邻近块体的地方，我们展示了地震过程的演化。我们确定并研究了形成于2022-2023年的Darkhad地震群的震源带，并将其分为几个序列，其中较大的震级为ML >；5. 在Hubsugul震源带激活的同时，我们在过去的大地震震源带观测到高地震活动：1991年的business gol事件，2011-2012年的Tuva事件和2008年的Belin-Bii-Kham事件。呼素古尔地震对阿尔泰-萨扬和贝加尔湖带边界块体地震活动性的作用与2003年楚亚地震对阿尔泰地震活动性的作用不同。

期刊介绍： Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
