Аннотация: A quasi stationary three dimensional model of electric fields and currents in the conductor that includes the Earth's atmosphere and ionosphere is created. The results of the three dimensional model are simpler regarding interpretation and explanation than two dimensional ones. Known approaches regarding the ionosphere as a boundary condition at the upper boundary of the atmospheric conductor are analyzed. For the investigation of the electric field penetration from ground into the ionosphere it is sufficient to take into account only integral conductivity of the ionosphere. A mathematical simulation has shown that the resulting electric field in the ionosphere is negligible in contrast to the general point of view that such a penetration is a physical process which potentially creates ionospheric precursors of earthquakes.

Аннотация: It is well known that lithospheric electromagnetic emissions are generated before earthquakes occurrence. In our study, we consider the physical penetration mechanism of the electric field from the Earth's surface, through the atmosphere-ionosphere layers, and until its detection in space by satellites. A simplified approach is investigated using the electric conductivity equation, i.e., del((sigma) over cap.del Phi) = 0 in the case of a vertical inclination of the geomagnetic field lines. Particular interest is given to the conductivity profile near the ground and the electric field distribution at the Earth's surface. Our results are discussed and compared to the models of Pulinets et al. (2003) and Denisenko et al. (2008). It is shown that the near ground atmospheric layer with low conductivity decreases the electric field penetration into the ionosphere. The model calculations have demonstrated that the electric field of lithospheric origin is too weak to be observed at satellite altitudes.

Аннотация: A mathematical model has been proposed for describing quasi-stationary atmospheric electric fields with approximate, but fairly accurate allowance for ionospheric conductivity. It is shown that some well-known models of electric field penetration from the Earth into the ionosphere have been deemed inadequate, though they work well in the atmosphere below 50 km. In these models, the arbitrarily specified boundary condition in the upper boundary of the atmosphere omits the existing good conductor or adds not existent conductor. The maximum possible field in our model is far less than in models where ionospheric conductivity is not taken into account, but vastly larger than in models based on the approximation with infinite Pedersen conductivity in the upper ionosphere.

Аннотация: In the used model, the quasistationary electric field in the atmosphere of the Earth is obtained by solving the conductivity equation. The penetration characteristics of the electric field from the Earth's surface into the ionosphere depend on both atmospheric and ionosphere conductivity. The ionosphere is taken into account by setting a special condition on the upper boundary of the atmosphere. The influence of the atmospheric surface layer with a reduced conductivity on the penetration of the electric field from the surface of the Earth into the ionosphere is analyzed.

Аннотация: Known models of the penetration of the electric field from the Earth’s surface to the ionosphere due to the electric conductivity of the atmosphere, including models with external currents, are analyzed. Principle disadvantages of models predicting a considerable penetration of the field to the ionosphere are described. It is shown that the penetrating fields are too weak and this makes it impossible to detect them in data of satellite measurements on the background of usual ionospheric fields. A conclusion is made about the necessity to study other physical processes providing the influence of lithospheric processes on the ionosphere. © 2015, Pleiades Publishing, Ltd.

Аннотация: The largest part of solid minerals (with the exception of those which are at the earth's surface) is being extracted world-wide by surface and underground mining techniques, with adits, mines and other mine workings being used. A considerable amount of mineral deposits (including oil reservoirs) is located either close to a fault-line or immediately within the zone of high seismic activity. To prevent economic and environmental damage under the effect of an earthquake, thorough seismic monitoring of the area must be performed, as well as the study of all possible mechanisms of an earthquake occurrence. In analysing the trigger effect of moon-and sun-induced tidal forces on seismic activity, six great earthquakes which occurred close to equatorial latitude over the last 15 years have been considered. Based on the positions of the Sun and Moon during the day relative to the point mass, the maps of horizontal, vertical components and vector of gravitational forces per unit mass have been plotted. The developed technique can be applicable to a set of methods to study integration and stress unloading mechanisms at the boundaries of block structures.

    Расчет и анализ триггерного эффекта приливных сил на наиболее крупные землетрясения
[Текст] : статья / Даниил Леонидович Чубаров, Владимир Алексеевич Кочнев // Известия Томского политехнического университета. Инжиниринг георесурсов. - 2016. - Т. 327, № 2. - С. 59-64 . - ISSN 2500-1019

Аннотация: Большая часть твердых полезных ископаемых в мире (за исключением тех, что находятся на поверхности земли) добывается открытым и закрытым способом посредством штолен, шахт и других горных выработок. Немалая часть месторождений полезных ископаемых (в том числе и нефтяных) располагаются либо вблизи, либо непосредственно внутри зон повышенной сейсмологической активности (сюда можно отнести все месторождения Чили, Японии, Индонезии, некоторые месторождения США, России и других стран). Таким образом, если вблизи данных месторождений произойдет крупное землетрясение, то, вероятнее всего, это приведет, с одной стороны, к приостановке (или консервации) деятельности месторождения, с другой - к значительному числу жертв и экономическому ущербу. Чтобы избежать или хотя бы минимизировать данный ущерб, необходимо проводить полноценный сейсмологический мониторинг данных территорий, а также изучать все возможные причины возникновения землетрясений. Данная работа направлена на изучение природы землетрясений, что, несомненно, говорит об актуальности исследования. Цель данного исследования: установить совместное триггерное воздействие гравитационных сил Луны и Солнца на сейсмологическую активность зон Земли. Методы исследования. В данной работе за основу взята известная физико-математическая модель (приливная модель Дж. Дарвина), а таrже принято во внимание изменение относительного положения Луны и Солнца. Результаты. При изучении триггерного воздействия приливных сил на сейсмологическую активность рассмотрены 6 наиболее крупных землетрясений, произошедших вблизи экваториальной широты за последние 15 лет. Построены изображения горизонтальных, вертикальных компонент и модулей вектора гравитационных сил на единичную массу в зависимости от взаимного положения Луны и Солнца в течение суток относительно исследуемого объекта с единичной массой. Проанализировано воздействие приливных сил на точки эпицентров 6 крупнейших землетрясений, произошедших вблизи экваториальной широты. Разрабатываемая технология может быть полезна в комплексе методов при изучении механизмов интегрирования и разрядки напряжений на границах блоковых структур.
The majority of solid minerals in the world (excluding those, which are on the Earth’s surface) are mined by the open- and close-cut techniques using adits, mines and other minings. A large part of deposits of minerals (including the oil ones) occur either close or just inside the areas of higher seismological activity (all deposits in Chilly, Japan, Indonesia, some deposits in the USA, Russia and other countries can be referred to this type). Thus, if a major earthquake occurs near such deposit it will probably result in suspension (conservation) of the deposit activity, on the one hand, and on the other hand in significant amount of victims and economic damage. In order to avoid or at least to minimize the damage it is necessary to monitor the seismological situation in these territories and to study all possible causes of earthquake occurrence. The paper is devoted to the study of the earthquake nature. This is the relevance of the research. The aim of the study is to establish the combined effect of the gravitational forces of the Moon and Sun on the Earth’s seismological activity zones. Methods. Physical and mathematical model (G. Darwin tidal model) is taken as a basis, and the combined effect of the Moon and Sun and their relative positions are taken into account. Results. The authors have studied six largest earthquakes with epicenters located near the equator during the last 15 years and prepared a map of horizontal and vertical components and the magnitudes of gravitational force, depending on the relative position of the moon and the sun. The influence of tidal forces on epicenters of six greatest earthquakes, located near the equator, was analyzed. The developed technique can be useful for studying the mechanisms of stress at the boundaries of block structures.

Аннотация: It was shown the technique of seismic hazard assessment based on comprehensive use of methods of seismic microzonation. This technique consists of four steps. The first step is to collect geological, seismological, geophysical and topographic information. Each layer according to geological engineering survey and geophysical work are assigned physical and mechanical properties (density, limit shear stress) and the P-And S- wave velocity. Next (step 2) after visualization and examination input data using GIS technologies 3D modelling of the geological environment is performed (it is created a grid each point of which is referred to coordinates of the site). The number and depth of soil are set in each point based on geological drilling data. Then (step 3) at each point seismic intensity are calculated using instrumental methods including the method of acoustic impedance and computer simulation (GRUNT program). At the last stage according to the analysis of the results of theoretical and instrumental methods seismic microzonation map are created using GIS technologies. The procedure of constructing maps uses different methods of selection areas with the same seismic hazard (kriging, spline interpolation).

    Modelling the mechanical structure of extreme shear ruptures with friction approaching zero generated in brittle materials

Аннотация: Experiments on frictional stick-slip instability in brittle materials and natural observations show that friction falls towards zero in the head of shear ruptures propagating with extreme velocities (up to supershear levels). Although essential for understanding earthquakes, fracture mechanics and tribology the question of what physical processes determine how weakening occurs is still unclear. Here, using a mathematical model, we demonstrate that the extremely low friction can be caused by a fan-like fault structure formed on the basis of a tensile-cracking process observed in all extreme ruptures. The mathematical model visualises and describes the fan-structure as a mechanical system during rupture propagation. It explains some features observed in laboratory experiments.

Аннотация: Seismogenic models have been recently proposed to explain precursors before earthquakes occurrences. Those models refer to physical processes linking the lithosphere, the atmosphere, and the ionosphere. We analyze in this work the curl-free current model describing the current flow from the lithosphere to the ionosphere through the atmosphere. We use a numerical simulation based on the finite element method to derive the current between the ground and the ionosphere. We have shown that the curl-free approximation of the atmospheric current density leads to significant and unpredictable distortions of the solutions of the electrical conductivity. Hence, it incorrectly expands the ionospheric disturbed region associated to lithospheric currents. It is shown that horizontally homogeneous vertical underground external currents cannot create currents from ground to the atmosphere.

    A mathematical model of quasistationary electric field penetration from ground to the ionosphere with inclined magnetic field
/ V. V. Denisenko [et al.] // J. Atmos. Sol.-Terr. Phys. - 2018, DOI 10.1016/j.jastp.2018.09.002 . - Article in press. - ISSN 1364-6826
Аннотация: A quasi stationary model of the electric fields and currents in the conductor that includes the Earth's atmosphere and ionosphere is developed. The role of the inclination of the magnetic field is considered. A mathematical simulation has shown that the resulting electric field in the ionosphere decreases. The penetration of the electric field and current from the ground to the ionosphere can be a physical process which creates observed ionospheric precursors of earthquakes only if the electric field strength and conductivity of the air near ground as well as the size of the pre-earthquake perturbations zone can simultaneously reach extreme possible values. Additional experiments are necessary to verify such a possibility. Other models are analyzed and compared to the main outcomes of our investigations. © 2018 Elsevier Ltd

/ A. Zotin [et al.] // Procedia Computer Science : Elsevier B.V., 2019. - Vol. 159: 23rd International Conference on Knowledge-Based and Intelligent Information & Engineering Systems, KES 2019 (4 September 2019 through 6 September 2019, ) Conference code: 141548. - P1642-1651, DOI 10.1016/j.procs.2019.09.334 . -
Аннотация: The paper is devoted to the analysis of the features of the EWH parameter change over the geoid using satellite measurements of the GRACE space system. These local gravitational anomalies are studied depending on the geometrical characteristics of the focal zones of the strongest underwater earthquakes in the period 2003-2016. The statistical processing of satellite observations data using the histogram and maximum entropy methods was performed. Completed interpretation and obtained estimates showing differences and similarities in observational data, due to the peculiarities of the structure of the studied geomedia and the corresponding focal areas. The final result is a statistical description of the space of anomalies of the gravitational field of the Earth as a whole and features of local gravitational anomalies over the focal zones of underwater strong earthquakes in the period from 2003 to 2016. © 2019 The Author(s).
