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: The classic approach to calculate the electrostatic field penetration, from the Earth's surface into the ionosphere, is to consider the following equation del. ((sigma) over cap del Phi) =0 where (sigma) over cap and Phi are the electric conductivity and the potential of the electric field, respectively. The penetration characteristics strongly depend on the conductivities of atmosphere and ionosphere. To estimate the electrostatic field penetration up to the orbital height of DEMETER satellite (about 700 km) the role of the ionosphere must be analyzed. It is done with help of a special upper boundary condition for the atmospheric electric field. In this paper, we investigate the influence of the ionospheric conductivity on the electrostatic field penetration from the Earth's surface into the ionosphere. We show that the magnitude of the ionospheric electric field penetrated from the ground is inverse proportional to the value of the ionospheric Pedersen conductance. So its typical value in day-time is about hundred times less than in night-time.

    The refinement of hypocenter parameters on the basis of three-dimensional velocity models of focal zones
/ L. B. Slavina, N. B. Pivovarova // Physics of the Earth and Planetary Interiors. - 1982. - Vol. 30, Is. 2-3. - P161-168 . - ISSN 0031-9201

Аннотация: A complex approach to the processing of seismological data to determine hypocenter coordinates and to construct three-dimensional velocity fields of focal zones is considered. The iterative process includes the determination of focal coordinates under the assumption of a laterally homogeneous medium, the construction of a three-dimensional velocity model, and subsequent redefinition of the focal coordinates taking into account the inhomogeneous structure of the medium. The principal results of calculations of three-dimensional velocity fields and refined earthquake hypocenters are presented for focal zones in Vrancea (Carpathians), the Caucasus, and Kamchatka.

    Computational modeling of the waves propagation in a block medium with viscoelastic interlayers
[Text] / O. V. Sadovskaya, V. M. Sadovskii, M. P. Varygina // ECCOMAS Thematic Conference - COMPDYN 2013: 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering, Proceedings - An IACM Special Interest Conference. - 2013. - P4578-4592

Аннотация: In the framework of mathematical model of a block medium with elastic blocks interacting through compliant viscoelastic interlayers and its approximation on the basis of equations of the Cosserat continuum, the problems of periodic perturbation of a layer and of a half-space under the action of distributed and localized surface loads are solved numerically. The simple formulas are suggested to determine the elasticity coefficients of the moment continuum by given characteristics of the materials of blocks and interlayers, which provide a good correspondence of the wave fields received by means of the exact and approximate models. Parallel computational algorithms, based on models of the inhomogeneous elasticity theory and the Cosserat elasticity theory, are applied to the analysis of propagation of elastic waves in geomaterials with layered and block microstructure. These algorithms are realized as parallel program systems for GPUs (using CUDA technology) and for multiprocessor computers of the cluster type (using MPI library). Monotone grid-characteristic schemes with a balanced number of time steps in elastic layers or blocks and in viscoelastic interlayers are used. By the analysis of numerical solutions it is shown that the multiblock medium has a resonant frequency of rotational motion of blocks, and this frequency does not depend on the size of a massif and on the boundary conditions at its surface.

    Phenomenological modeling ofdeformation of porous and cellular materials taking into account the increase in stiffness because of the collapse of pores

Аннотация: Mathematical model for the description of deformation of a porous material with a random distribution of pores is constructed on the basis of generalized rheological method taking into account the different resistance of a material to tension and compression. Phenomenological parameters of the model are determined by means of the approximate computations for the problem of static loading of a cubic periodicity cell with spherical cavities. Within the framework of this theory the fields of displacements and stresses around expanding cavity of spherical shape in a homogenious space are constructed. It is shown that the porosity does not change at the stage of elastic deformation. When the pressure increases, a zone of plastic compaction is formed in the vicinity of a cavity, and in a part of this zone the collapse of pores takes place. Engineering formulas for calculation of critical pressures of the elastic limit state and the limit state of a medium with open pores, and also the formulas for determining the radiuses of interfaces of zones of plasticity and compaction are obtained. A complex of parallel programs for numerical analysis of the dynamic deformation of porous materials on multiprocessor computer systems is worked out. By means of this complex a series of computations for deformation of the protection elements, made of metal foams, under the action of localizedim pulsive loads was performed. The random nature of distribution of the pores size is taken into account with the help of computer modeling. Computations allow one to estimate plastic dissipative part of the energy of impact.

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).

Аннотация: The fan-shaped mechanism of rotational motion transmission in a system of elastically bonded slabs on flat surface, simulating the propagation of shear ruptures in super brittle rocks, is analyzed. Such ruptures appear in the Earth's crust at seismogenic depths. They propagate due to the nucleation of oblique tensile microcracks, leading to the formation of a fan domino-structure in the rupture head. A laboratory physical model was created which demonstrates the process of fan-structure wave propagation. Equations of the dynamics of rotational motion of slabs as a mechanical system with a finite number of degrees of freedom are obtained. Based on the Merson method of solving the Cauchy problem for systems of ordinary differential equations, the computational algorithm taking into account contact interaction of slabs is developed. Within the framework of a simplified mathematical model of dynamic behavior of a fan-shaped system in the approximation of a continuous medium, the approximate estimates of the length of a fan depending on the velocity of its motion are obtained. It is shown that in the absence of friction a fan can move with any velocity that does not exceed the critical value, which depends on the size, the moment of inertia of slabs, the initial angle and the elasticity coefficient of bonds. In the presence of friction a fan stops. On the basis of discrete and continuous models, the main qualitative features of the behavior of a fan-structure moving under the action of applied tangential forces, whose values in a laboratory physical model are regulated by a change in the inclination angle of the rupture plane, are analyzed. Comparison of computations and laboratory measurements and observations shows good correspondence between the results.

Адекватная оценка параметров источника цунами от ожидаемого цунамигенного землетрясения и, соответственно, предвычисление распространения цунами обеспечивают предварительную оценку опасности цунами. В рамках информационного обеспечения решения поставленной задачи рассмотрены классические способы оценки параметров источника цунами на основе анализа форшокового процесса, блочно-клавишной и поршневой моделей. Для поиска и анализа вариантов конфигурации и местоположения изучаемого источника предлагаются алгоритмы и методика расчетов, включающая нелинейную регрессию для построения аппроксимационных функций и метод построения упругих сеток для кластеризации пространственных данных.
The study is devoted to the development of algorithmic support for the data processing and comparative analysis of various models of tsunami source parameter estimation, which are based on the geomonitoring data of the tsunamigenic earthquake preparation for the selected source area. An adequate assessment of the tsunami source parameters from the expected tsunamigenic earthquake and, accordingly, the precomputation of tsunami distribution provide a preliminary assessment of the tsunami hazard. Within the information support framework for the solution of the problem, classical methods for tsunami source parameters estimation are analyzed, based on foreshock process analysis, block-key and piston source models. For the search and analysis of configuration options and the location of the source, algorithms and calculation techniques are proposed, including nonlinear regression for constructing approximation functions and a method for constructing elastic grids for clustering spatial data.

Аннотация: Исследование посвящено анализу сейсмической активности Земли с целью поиска закономерностей, связанных с внешними космическими факторами, циклическими по своей природе. На основе гистограммного подхода, с применением Фурье- и вейвлет-анализа изучаются особенности связи астрономических явлений (фаза Луны и др.) и проявлений сильных землетрясений, а также с глобальной сейсмичностью.
The study is devoted to the analysis of the Earth ’s seismic activity in order to search for regularities related to external cosmic factors, cyclic in nature. On the basis of the histogram approach, using Fourier and wavelet analysis, the features of the connection of astronomical phenomena (the phase of the Moon, etc.) and manifestations of strong earthquakes, with global seismicity are studied.

    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
