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.

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: Planetary embryos form protoplanets via mutual collisions, which can lead to the development of magma oceans. During their solidification, significant amounts of the mantles' volatile contents may be outgassed. The resulting H2O/CO2 dominated steam atmospheres may be lost efficiently via hydrodynamic escape due to the low gravity of these Moon- to Mars-sized objects and the high stellar EUV luminosities of the young host stars. Protoplanets forming from such degassed building blocks after nebula dissipation could therefore be drier than previously expected. We model the outgassing and subsequent hydrodynamic escape of steam atmospheres from such embryos. The efficient outflow of H drags along heavier species like O, CO2, and noble gases. The full range of possible EUV evolution tracks of a young solar-mass star is taken into account to investigate the atmospheric escape from Mars-sized planetary embryos at different orbital distances. The estimated envelopes are typically lost within a few to a few tens of Myr. Furthermore, we study the influence on protoplanetary evolution, exemplified by Venus. In particular, we investigate different early evolution scenarios and constrain realistic cases by comparing modeled noble gas isotope ratios with present observations. Isotope ratios of Ne and Ar can be reproduced, starting from solar values, under hydrodynamic escape conditions. Solutions can be found for different solar EUV histories, as well as assumptions about the initial atmosphere, assuming either a pure steam atmosphere or a mixture with accreted hydrogen from the protoplanetary nebula. Our results generally favor an early accretion scenario with a small amount of residual hydrogen from the protoplanetary nebula and a low-activity Sun, because in other cases too much CO2 is lost during evolution, which is inconsistent with Venus' present atmosphere. Important issues are likely the time at which the initial steam atmosphere is outgassed and/or the amount of CO2 which may still be delivered at later evolutionary stages. A late accretion scenario can only reproduce present isotope ratios for a highly active young Sun, but then unrealistically massive steam atmospheres (few kbar) would be required.

Аннотация: Sources of magnetic field are often approximated by dipoles or current loops, however it this work they are approximated by magnetized prisms instead, which is possible due to equivalency between magnetized objects and currents. Distribution of effective magnetization is then obtained by solving inverse magnetometry problem using the adaptive method of refining the unknown values based on discrepancy between initial values and model values. Z-components of Earth’s magnetic field in IGRF-2005 model in geocentric coordinate system are used as initial values. This allows obtaining the distribution of volumetric currents and magnetic moments for the Earth’s core, which is found to be significantly asymmetric, with four major anomalies, corresponding to surface anomalies: Australian, Canadian, South-Atlantic and Siberian. Work contains additional analysis of the model, initial values and features of the used method in relation to obtained result. Potential source of energy maintaining the currents is suggested, in form of tidal forces, caused by the gravitational influence of the Moon and the Sun. © 2018, International Multidisciplinary Scientific Geoconference.
