Abstract—The hydrogeology of fault zones, especially at considerable depth, is perhaps a most underdeveloped field in earthquake source mechanics. This is due to both the lack of the data on the filtration characteristics of the geomaterial at large depths and to the complexity of the processes of mass transfer, fracture formation and healing under high temperatures and pressures. In this case, the strong influence of fluid on both the friction characteristics and the stress conditions in the vicinity of the slip zone is obvious. Fluids are carriers of dissolved matter and thermal energy, an effective catalyst for various types of metamorphic transformations. According to some models, fluid flows can be triggers for the initiation and arrest of seismogenic ruptures. The current trend in world seismology to constructing a complex computational model that adequately describes the processes of preparation, initiation, and arrest of various fault slip modes requires developing the ideas about fluid dynamics of seismogenic faults. This review considers the information on hydrogeology of fault zones obtained in recent years. Models and ideas involving field data, laboratory and field experiments and numerical calculations regarding the role of fluids at different stages of the seismic cycle are analyzed.

摘要--断层带的水文地质学,尤其是相当深的断层带的水文地质学,也许是震源力学中最不发达的一个领域。这既是由于缺乏有关大深度地质材料过滤特性的数据,也是由于高温高压下质量传递、断裂形成和愈合过程的复杂性。在这种情况下,流体对滑动带附近的摩擦特性和应力条件的影响是显而易见的。流体是溶解物质和热能的载体,是各种变质转化的有效催化剂。根据一些模型,流体流动可以成为引发和阻止地震破裂的触发器。当前,世界地震学的趋势是构建一个复杂的计算模型,以充分描述各种断层滑动模式的准备、启动和停止过程,这就需要发展有关震源断层流体动力学的思想。本综述介绍了近年来获得的有关断层带水文地质的信息。文中分析了有关流体在地震周期不同阶段的作用的模型和观点,包括现场数据、实验室和现场实验以及数值计算。

Search for Pulsed Ultralow-Frequency Electromagnetic Precursors of Earthquakes 寻找地震的脉冲超低频电磁前兆

AbstractNumerous publications have appeared in the literature describing a new seismo-electromagnetic effect—the appearance of magnetic pulses with a duration of 1–40 s, which are detected at distances up to ten thousand km a few minutes before earthquakes of even low magnitude. An assumption was made about the universality of the processes responsible for generation of pulsed precursors and the fundamental possibility of a short-term (a few minutes) warning of an approaching earthquake. In this article, the possibility of the occurrence of ultra-low-frequency pulses that precede seismic events with magnitudes M > 5.0 is studied based on the data from a network of induction magnetometers in the Far East. Pulsed disturbances occur regularly in the records by these highly sensitive magnetometers. Some pulses are observed synchronously at several stations, which excludes their origin from local noise. The spectral maximum of about 7–8 Hz of the oscillatory structure, which appears in many pulses, corresponds to the fundamental frequency of the Schumann resonator. A comparison of magnetic observations with data from the World Wide Lightning Location Network (WWLLN) showed that some of the pulses were caused by lightning discharges in the 650 km vicinity of magnetic station. Although some of the impulses are observed immediately before earthquakes, their connection with seismic activity cannot be claimed with certainty. The calculation of the number of pulses within the 5-min interval before and after the seismic shock shows that they are randomly distributed around the time of the earthquake. Apparently, the pulses are mainly due to the ionospheric response to a distant lightning discharge.

摘要--大量文献描述了一种新的地震电磁效应--持续时间为 1-40 秒的磁脉冲的出现,这种磁脉冲在震级很低的地震发生前几分钟就能在高达一万千米的距离上被探测到。我们假定脉冲前兆产生过程的普遍性,以及在短期内(几分钟)发出临近地震警报的基本可能性。本文根据远东感应磁强计网络的数据,研究了在震级为 M > 5.0 的地震发生前出现超低频脉冲的可能性。这些高灵敏度磁强计的记录中经常出现脉冲干扰。有些脉冲是在几个站点同步观测到的,这就排除了它们来自局部噪声的可能性。许多脉冲中出现的振荡结构的最大频谱约为 7-8 赫兹,与舒曼谐振器的基频一致。将磁场观测数据与全球闪电定位网络(WWLLN)的数据进行比较后发现,部分脉冲是由磁场站附近 650 公里范围内的闪电放电引起的。虽然有些脉冲是在地震前观测到的,但不能肯定它们与地震活动有关。对地震冲击前后 5 分钟间隔内脉冲数的计算表明,脉冲数是随机分布在地震发生前后的。显然,脉冲主要是电离层对远处闪电放电的反应。

On the Geomagnetic and Ionospheric Variations after the 2023 Strong Eruption of the Shiveluch Volcano 论 2023 年希维鲁奇火山强烈喷发后的地磁和电离层变化

Abstract—Ground-based magnetometers and vertical ionospheric sounding stations were used to record specific variations in the geomagnetic field, caused by the perturbation in the lower ionospheric current systems, and specific variations in the upper ionospheric electron density after a strong volcanic eruption in Kamchatka, Russia, on April 10, 2023. The analysis of the measurements from two series of explosions has shown that the impact on the lower ionosphere is realized via both seismic Rayleigh waves (which are a source of acoustic waves propagating into the ionosphere), and atmospheric internal gravity waves generated by explosions. At distances up to a thousand km from the source, a repeatability of the pattern of ionospheric perturbations after each of the six volcanic explosions is discovered. At larger distances, signals from acoustic waves caused by the Rayleigh waves are clearly recorded in the ionosphere, whereas separation of the signals from atmospheric internal waves is difficult due to the influence of perturbations from other external sources.

摘要-2023 年 4 月 10 日俄罗斯堪察加半岛发生强烈火山爆发后,使用地基磁强计和 垂直电离层探测站记录了电离层下层电流系统扰动引起的地磁场具体变化以及电离 层上层电子密度的具体变化。对两个系列爆炸的测量结果进行的分析表明,对低层电离层的影响是通过地震瑞利波(传播到电离层的声波源)和爆炸产生的大气内部重力波实现的。在距离震源不超过一千公里的地方,发现六次火山爆发后电离层扰动的模式具有重复性。在更远的距离上,电离层中清楚地记录了由瑞利波引起的声波信号,而由于其他外部来源的扰动的影响,很难将大气内波信号分离出来。

Abstract—It is generally recognized that the formation of the fold-and-thrust tectonic structures of mobile belts on continents is associated with crushing and narrowing of the Earth’s crust due to collision of lithospheric plates. The deformation of the Caucasian lithosphere in the recent time is generally consistent with these ideas. However, the block differentiation of the Caucasian lithosphere brings specificity into the directionality of recent vertical and horizontal movements. In this paper, we analyze vertical movements of the Caucasus estimated by means of high-precision leveling over a period of more than a century and consider their spatial correlation with the tectonics, seismicity, stress-strain state, and geophysical fields. A clear correlation indicating the deep tectonic nature of the long-term uplifts of the Caucasus crust is revealed. The differentiation of the Arabian plate movement causes partitioning of the Caucasus territory into provinces that differ by the pattern of recent movements, orientation of faults, and stress-strain state of the geomaterial. These provinces also have distinctions in seismicity in terms of the number of seismic events and focal mechanisms of the earthquakes. We propose a model of a deformation mechanism of the Greater Caucasus, which accommodates the long-term trend of the Caucasus uplift in the conditions of general shortening of the Earth’s crust. The results of the analysis provide a basis for discussion of a probable mechanism of neotectonic evolution of the Greater Caucasus, which can be used in the seismic hazard assessment of the North Caucasus.

摘要--人们普遍认为,大陆移动带褶皱-推覆构造结构的形成与岩石圈板块碰撞导致的地壳挤压和缩窄有关。高加索岩石圈近期的变形与上述观点基本一致。然而,高加索岩石圈的块体分异给近期垂直和水平运动的方向性带来了特殊性。在本文中,我们分析了通过高精度水准测量估算的一个多世纪以来高加索地区的垂直运动,并考虑了其与构造、地震、应力应变状态和地球物理领域的空间相关性。结果表明,高加索地壳的长期隆起具有明显的深部构造性质。阿拉伯板块运动的分化导致高加索地区被划分为不同的省份,这些省份因近期运动模式、断层走向和地质材料的应力应变状态而有所不同。这些省份在地震事件的数量和震源机制方面也各不相同。我们提出了一个大高加索地区变形机制模型,该模型在地壳普遍缩短的条件下适应了高加索地区隆起的长期趋势。分析结果为讨论大高加索地区新构造演化的可能机制提供了基础,该机制可用于北高加索地区的地震灾害评估。

Abstract—The generalized cellular model based on the of Olami‒Feder‒Christensen cellular automaton model and modified by considering the durability of the material based on the kinetic concept of the strength of solids developed by Academician S.N. Zhurkov is used to model and clarify the nature of the statistical law of earthquake productivity. The modified model is named Olami‒Feder‒Christensen‒Zhurkov (OFCZ) model. The OFCZ model captures the main statistical regularities and patterns of seismicity: the Gutenberg‒Richter and Omori‒Utsu laws, the Bath’s law, fractal geometry of seismicity, and the law of earthquake productivity. It is shown that the clustering of model events (analogs of earthquakes), corresponding to the earthquake productivity law, is caused by the kinetic component of the OFCZ model. The dependences of productivity on material strength and temperature of the medium are obtained. The influence of the Zhurkov parameter and the cell transmission (coupling) parameter in the cellular model (dissipativity of the model) on the productivity is considered. It is shown that the revealed dependences of productivity on strength and temperature are consistent with the empirical data.

摘要 在 Olami-Feder-Christensen 蜂窝自动机模型的基础上,根据 S.N. Zhurkov 院士提出的固体强度动力学概念,考虑到材料的耐久性,对广义蜂窝模型进行了修改,用于模拟和阐明地震生产力统计规律的性质。修改后的模型被命名为 Olami-Feder-Christensen-Zhurkov(OFCZ)模型。OFCZ 模型捕捉到了地震的主要统计规律和模式:古登堡-里克特定律和奥莫里-乌津定律、巴斯定律、地震的分形几何以及地震生产力定律。研究表明,与地震生产力定律相对应的模型事件(地震模拟)的群集是由 OFCZ 模型的动力学分量引起的。研究得出了生产率与介质的材料强度和温度的关系。考虑了细胞模型中 Zhurkov 参数和细胞传输(耦合)参数(模型的离散性)对生产率的影响。结果表明,所揭示的生产率与强度和温度的关系与经验数据一致。

Abstract—A collection of igneous rocks of the Ukrainian Shield sampled from the Korsun-Novomyrhorod pluton (age interval 1760–1735 Ma, Ingul Domain) and from the Korosten pluton (age 1760–1750 Ma, North-Western Domain) is studied. The magnetic and thermomagnetic properties of samples were studied and X-ray diffraction analyses were carried out to obtain reliable determinations of paleointensity (Banc), It is shown that the carriers of the characteristic component of natural remanent magnetization are single- and small pseudo-single-domain magnetite grains. Banc was determined by two methods: through the Thellier‒Coe procedure with pTRM checks and by Wilson method. Paleointensity determinations are obtained from five sites and shown to meet quality criteria. For all sites, Banc and the virtual dipole moment (VDM) values are extremely low, varying within the ranges 3.6–9.76 μT and (0.92–2.43) × 1022 Am2, respectively. The analysis of the data from the paleointensity world database (WDB) indicates that the geodynamo operation mode in the Proterozoic can be characterized by an alternation of strong and weak dipole regimes, but the validity of this conclusion entirely depends on the reliability of data reported in the literature and presented in the WDB.

Abstract—We analyze the postseismic processes in the region of the Mw 8.2 Chignik earthquake, Alaska, which occurred on July 29, 2021. Using the model of the seismic rupture surface constructed in our previous work (Konvisar et al., 2023), we have modeled the viscoelastic relaxation process. The results indicate that by reducing the viscosity of the asthenosphere to 1018 Pa s we an achieve the displacement velocities that are close to those recorded at the coastal GPS sites. However, the displacements on the islands near the source zone of the earthquake differ significantly not only in magnitude but also in direction. At the same time, the constructed postseismic creep (afterslip) model agrees well with displacement data at the GPS sites and with the line-of-sight (LOS) displacement map derived from radar images taken from the descending orbit of the Sentinel-1A satellite. We also analyze temporal variations of gravity field in the earthquake region. The obtained coseismic anomaly is consistent with the anomaly calculated from the rupture surface model.

摘要-我们分析了 2021 年 7 月 29 日发生在阿拉斯加奇尼克 8.2 级地震区域的震后过程。利用我们之前的工作(Konvisar 等人,2023 年)中构建的地震破裂面模型,我们对粘弹性松弛过程进行了建模。结果表明,通过将岩浆层的粘度降低到 1018 Pa s,我们可以获得与沿海 GPS 站点记录相近的位移速度。然而,震源区附近岛屿上的位移不仅在幅度上,而且在方向上都有很大差异。同时,所构建的震后蠕变(后滑移)模型与全球定位系统站点的位移数据以及从哨兵-1A 卫星下降轨道拍摄的雷达图像中得到的视线位移图非常吻合。我们还分析了地震区域重力场的时间变化。得到的共震异常与破裂面模型计算出的异常一致。由于地震后一段时间内重力模型的时间序列不够长,因此还无法分离震后异常。对震后过程的分析将在本研究的第二部分继续进行(Smirnov 等人,2024 年),我们将各个 GPS 点的震后位移随时间的发展与余震活动进行比较,从而得出 Chignik 地震震源区震后过程的蠕变性质的结论。

Abstract—The paper presents the results of rock magnetic studies and relative paleointensity determinations from sediments of Lake Shira, Khakassia. Carrier minerals of natural remanent magnetization (NRM) were identified through hysteresis loop parameter measurements, thermomagnetic and X-ray diffraction (XRD) analyses. The sediment age was determined by radiocarbon dating; according to age estimates, the studied sediment sequence covers approximately the past 9100 years. To obtain high-quality relative paleointensity results, the determinations were made on linear segments of the pseudo-Arai‒Nagata diagrams. The quality was assessed by the criteria of the number of points in the calculations of slope, quality criterion (q), NRM fraction destroyed in the paleointensity determination interval, and relative paleointensity determination error (σ). According to the rock magnetic studies and XRD analysis, the magnetic carriers are mainly single-domain (SD) and pseudo-single-domain (PSD) magnetite and hematite. The comparison of the obtained relative paleointensity data with model paleointensities calculated for the Shira coordinates from the various models (CALS10K.1b (Korte et al., 2011), PFM9k.1 (Nilsson et al., 2014), HFM.OL1.AL1, CALS10k.2 ARCH10k.1 (Constable et al., 2016)), with absolute paleointensities and with the collection of results from the studies of sedimentary and igneous rocks and archaeomagnetic objects has shown that these data are in good agreement and share common trends. This provides grounds for applying this approach to paleointensity determination from bottom sediments of modern lakes using the pseudo-Thellier method.

摘要--本文介绍了对卡卡西亚希拉湖沉积物进行岩石磁性研究和相对古强度测定的结果。通过磁滞回线参数测量、热磁和 X 射线衍射(XRD)分析,确定了天然剩磁(NRM)载体矿物。沉积物的年代是通过放射性碳年代测定法确定的;根据年代估算,所研究的沉积序列大约涵盖了过去的 9100 年。为了获得高质量的相对古强度结果,测定是在伪新井长方图的线段上进行的。质量评估标准包括斜率计算中的点数、质量标准(q)、古地层强度测定区间内被破坏的 NRM 部分以及相对古地层强度测定误差(σ)。根据岩石磁性研究和 XRD 分析,磁性载体主要是单域(SD)和伪单域(PSD)磁铁矿和赤铁矿。将获得的相对古密度数据与各种模型(CALS10K.1b(Korte 等人,2011 年)、PFM9k.1(Nilsson 等人,2014 年)、HFM.OL1.AL1、CALS10k.2 ARCH10k.1(康斯特布尔等人,2016 年))、绝对古密度以及沉积岩、火成岩和考古磁性物体研究成果的收集表明,这些数据具有良好的一致性和共同的趋势。这就为使用伪泰勒法从现代湖泊底部沉积物中确定古密度提供了依据。

Abstract—Dynamic exploration and development of the Arctic zone of the Russian Federation is inextricably linked to the need to minimize risks to the technosphere, associated, among other things, with space weather effects on power equipment systems operated within the coverage of the auroral oval. At the same time, the concomitant monitoring of space weather parameters and variations of the geomagnetic field in the Arctic is carried out only by means of a small group of satellites and several dozens of magnetic stations located mainly in the USA, Canada, northern and central Europe. It is clear that the current situation practically excludes the possibility of operational diagnostics of the level of geomagnetically induced currents (GIC) for the most part of the Arctic zone of the Russian Federation, where, in fact, the only available indicator of space weather conditions are polar auroras. The paper proposes an approach to interpreting aurora appearance to assess space weather impact on high-latitude infrastructure facilities. Based on the case study of the “Vykhodnoy” substation of the “Severnyi Tranzit” (Northern Transit) main electric transmission line it is shown that when the aurora is observed in the north, at the zenith (overhead), and in the south relative to the observation point, the most probable (30-min average) GIC is 0.08, 0.23, and 0.68 A, respectively. At the same time, the probability of half-hourly average GIC exceeding 2 A (with auroras observed in the north, overhead, and in the south relative to the impacted object) is ~6, ~10, and ~15%, respectively. Finally, the ways to improving the proposed technique and the applicability limits of the approach are discussed.

摘要--俄罗斯联邦北极区的动态勘探和开发与尽量减少对技术层的风险的需要密不可分,这种风险除其他外与空间气象对极光椭圆覆盖范围内运行的电力设备系统的影响有关。与此同时,对空间气象参数和北极地磁场变化的同步监测只能通过一小组卫星和主要位于美国、加拿大、北欧和中欧的几十个磁力站来进行。显然,目前的情况实际上排除了对俄罗斯联邦北极区大部分地区的地磁感应电流水平进行业务诊断的可能性,事实上,那里唯一可用的空间气象条件指标是极地极光。本文提出了一种解释极光外观的方法,以评估空间天气对高纬度基础设施的影响。基于对 "Severnyi Tranzit"(北方过境)主要输电线路的 "Vykhodnoy "变电站的案例研究表明,当在观测点的北部、天顶(高空)和南部观测到极光时,最可能的(30 分钟平均值)GIC 分别为 0.08、0.23 和 0.68 A。同时,半小时平均 GIC 超过 2 A 的概率(极光在北面、上空和相对于受影响天体的南面观测到)分别为~6%、~10%和~15%。最后,讨论了改进拟议技术的方法以及该方法的适用范围。
