摘要

在完整的地震-地球动力学循环发展过程中，贝加尔湖裂谷系统中部的活动断层进入亚稳(震前)状态，决定了地震的时间。基于流体流动作为发震变形的可能触发因素，在确定2020-2023年贝加尔湖-库布苏古尔盆地恢复的地震时间时，我们考虑了:1)大气压力下降;2)不同站点氧化-氧化还原电位(ORP)的匹配-错配模式;3)Kultuk多面体监测站地下水总体ORP下降。

Relationship between timing of earthquakes of the Baikal-Khubsugul reactivation and oxidation–redox potential in groundwaters from the Kultuk polygon

Timing of earthquakes is determined by an entry of active faults in the central part of the Baikal Rift System into a metastable (preseismic) state during the development of a complete seismogeodynamic cycle. Based on a role of fluid flows as possible triggers for seismogenic deformations, in determining earthquake timing of the Baikal-Khubsugul reactivation of 2020–2023, we take into account: 1) decreasing atmospheric pressure, 2) matching–mismatching mode of oxidation–redox potential (ORP) in different stations, and 3) overall ORP decreasing in groundwaters from monitoring stations of the Kultuk polygon.
