Решена обратная задача по определению координат и времени источника возникновения сферической волны по множеству станций наблюдений (обратная четырехмерная засечка). Выполнено тестирование полученного решения при различном уровне помех. Обратная четырехмерная засечка, может применяться в навигационных системах, геодезии и сейсмологии. Полученное решение применено для глобального сейсмического каталога и найдено распределение вероятных источников возбуждения деформаций внутри Земли. Основное число сингулярных источников сферических деформационных фронтов сосредоточено в ядре Земли (R<3000 км -93,7 %). Выделены отдельные кластеры источников вероятных деформаций и построены разрезы Земли с распределением сингулярных источников первичных деформаций. Применение обратной четырехмерной засечки для найденного каталога источников первичных сингулярных деформаций дает с хорошей точностью распределение исходных землетрясений в земной коре и верхней мантии.The inverse problem is solved to determine the coordinates and time of the source of the spherical wave from many observation stations (inverse four-dimensional mark). The resulting solution was tested at different interference levels. The inverse four-dimensional mark can be used in navigation systems, geodesy and seismology. The resulting solution was applied to the global seismic catalog and the distribution of probable sources of deformation excitation inside the Earth was found. The main number of singular sources of spherical deformation fronts is concentrated in the Earth’s core (R < 3000 km -93,7%). Separate clusters of sources of probable deformations are identified and Earth sections with distribution of sources of primary deformations are constructed. The application of the inverse four-dimensional notch to the found catalog of sources of primary singular deformations gives with good accuracy the distribution of the original earthquakes in the Earth’s crust and upper mantle.

Глобальная деформационная модель по предлагаемой методике строиться в два этапа. На первом этапе, в предположении волновой природы сейсмичности, строится модель первичных син- гулярных источников деформационного процесса. Для этого применяется алгоритм прямой локации семейства источников деформационных волн по глобальному сейсмическому каталогу или по каталогу комплексных геодинамических индикаторов. На втором этапе, на основе решения линейной обратной задачи, семейство сингулярных источников наделяется амплитудными характеристиками. Для этого используются мировые каталоги скоростей GPS/GNSS, на основе которых ставится и решается линей- ная обратная задача. Таким образом, было построено семейство первичных сингулярных источников возможных деформационных фронтов для Земли. Основная масса этих источников сосредоточена вну- три ядра (R<3000 км, 93.7 %). Применение обратной четырехмерной засечки для найденного множе- ства источников первичных сингулярных деформаций позволяет восстановить с хорошей точностью исходный каталог землетрясений в земной коре и верхней мантии. Даются формулы для расчета всех элементов тензора деформаций и трех главных инвариант деформационного тензора. Описан способ снижения размерности обратной линейной задачи. Изучается структура полученного решения путем расчета различных элементов динамического деформационного тензора.
The global deformation model according to the proposed method is built in two stages. At the fi rst stage, under the assumption of the wave nature of seismicity, a model of primary singular sources of the deformation process is built. To do this, the algorithm of direct location of the family of sources of deformation waves on the global seismic catalog or on the catalog of complex geodynamic indicators is used. At the second stage, based on the solution of the linear inverse problem, the family of singular sources is endowed with amplitude characteristics. For this, world directories of GPS/GNSS speeds are used, on the basis of which a linear inverse problem is set and solved. Thus, a family of primary singular sources of possible deformation fronts for the Earth was built. The bulk of these sources are concentrated inside the core (R < 3000 km, 93.7%). The use of inverse four-dimensional serifs for the found set of sources of primary singular deformations makes it possible to restore with good accuracy the original catalog of earthquakes in the earth’s crust and upper mantle. Formulas are given for calculation of all elements of strain tensor and three main invariants of strain tensor. Described is a method of reducing the dimension of an inverse linear problem. The structure of the resulting solution is studied by calculating various elements of the dynamic strain tensor.

Published: July 2024

Выполнено изучение Катав-Ивановского грязевого оползня геофизическими методами по двум профилям в эпицентральной зоне одноименного землетрясения (5.09.2018, М5.8). Применялся комплекс методов: магнитометрия, многочастотное электромагнитное профилирование, аудиомагнитотеллурическое зондирование (АМТЗ). Получены глубинные разрезы намагниченности, кажущегося сопротивления и проводимости. Выявлена система суб- вертикальных тектонических нарушений и субгоризонтальные границы коры выветривания и обводненной зоны трещиноватости. Тектонические нарушения проявлены положительными аномалиями магнитного поля (20–60 нТл), узкими зонами (10–20 м) пониженного электрического сопротивления горных пород, повышенной электрической проводимостью и поверхностными трещинами в бортах оползня. Глубина границы коры выветривания по данным АМТЗ и инверсии магнитного поля в намагниченность среды составляет 10–20 м, а обводненной зоны трещиновато- сти 60–75 м. В коре выветривания имеются глубокие карманы в зонах тектонических нарушений. Оползень является наиболее вероятным местом тектонического удара Катав-Ивановского земле- трясения с разрывом сплошности геологической среды.
The study of the Katav-Ivanovsky mud landslide by geophysical methods was carried out along two profi les in the epicentral zone of the same named earthquake (09/05/2018, M5.8). Magnetometric survey, multi-frequency electromagnetic profi ling with AEMP-14 equipment and audio magnetotelluric sounding was used. Deep sections of magnetization, apparent resistance and conductivity are obtained. A system of sub-vertical tectonic faults and sub-horizontal boundaries of the weathering crust and the fl ooded fracture zone were revealed. Tectonic disturbances are manifested by magnetic fi eld anomalies of 20-60 nT, narrow zones (10-20 m) of reduced electrical resistance of rocks by 3000-3500 ohm·m, contacts of blocks of different (by 100-200 ohm·m) electrical resistance, increased electrical conductivity and surface cracks in the sides of the landslide. The boundary depth of the weathering crust according to audio magnetotelluric sounding and the inversion of the magnetic fi eld into the magnetization is 10–20 m, and the depth of the watered fracture zone is 60–75 m. There are deep pockets in the weathering crust in zones of tectonic faults. The landslide is the most probable place of the tectonic impact of the Katav-Ivanovsk earthquake with a break in the continuity of the geological environment.

Целью работы являлось изучение особенностей размещения и локализации рудопроявлений меди в пермских отложениях осадочного чехла Предуральского краевого прогиба, передовых складок Урала и восточной части Русской платформы относительно радиально-концентрических структур, выявленных по результатам дешифрирования космических фотоснимков, сейсмотектоническим и геоморфологическим данным. Исследования показали, что в строении, распределении и локализации месторождений меди в пермских отложениях есть много общего с размещением залежей углеводородов. Месторождения имеют пластовую и линзовидную форму залежей, субгоризонтальное залегание, латерально-вертикальную зональность, многоярусное строение продуктивных толщ, приуроченность к соляной тектонике, цветковым и радиально-концентрическим структурам. Сделан вывод о том, что, возможно, их объединяет общий генезис, связанный с современными геодинамическими процессами в земной коре. Месторождения медистых песчаников в надсолевых отложениях могут быть продуктом вертикальной миграции гидротермальных растворов по неотектоническим разрывным нарушениям из глубоких горизонтов.The aim of this work was to study the distribution and localization of copper ore occurrences in the Permian deposits of the sedimentary cover of the Cis-Ural foredeep, the frontal folds of the Urals and the eastern part of the Russian Platform with respect to radial-concentric structures identifi ed by the results of interpretation of space photographs, seismotectonic and geomorphological data. Studies have shown that in the structure, distribution and localization of copper deposits in Permian deposits, there is much in common with the location of hydrocarbon deposits. The deposits have a sheet and lenticular form of deposits, subhorizontal occurrence, lateral-vertical zoning, a multi-tiered structure of productive strata, confi nement to salt tectonics, fl oral and radialconcentric structures. It is concluded that, perhaps, they are united by a common genesis associated with modern geodynamic processes in the earth’s crust. Deposits of cupriferous sands in post-salt deposits may be the product of vertical migration of hydrothermal solutions along neotectonic faults from deep horizons.

The vertex set of Γ(F1×F2×F3) (Γ(J1×J2 ×J3)) is Z∗(F1 ×F2 ×F3) (Z∗(J1 ×J2 ×J3)), the set of non-zero zero divisors, and two distinct vertices (x1, x2, x3), (y1, y2, y3) are adjacent if and only if (x1, x2, x3) · (y1, y2, y3) = (0, 0, 0), the additive identity of the ring F1 × F2 × F3 (J1 × J2 × J3). The vertex set of Join graph Γ(F1 × F2 × F3) + Γ(J1 × J2 × J3) is V (Γ(F1 × F2 × F3)) ∪ V (Γ(J1 × J2 × J3)) and edge set is E(Γ(F1 × F2 × F3)) ∪ E(Γ(J1 × J2 × J3)) ∪ {(x1, x2, x3) · (y1, y2, y3) : (x1, x2, x3) ∈ V (Γ(F1 × F2 × F3)), (y1, y2, y3) ∈ V (Γ(J1 × J2 × J3))}.

The study of language and literature today are inseparable. Unfortunately, the phenomenon of Indonesian learning in junior high schools is in a hesitant position due to the lack of formulating literature as teaching material including indigenous wisdom-based literature that can threaten the extinction of indigenous literature. At Buru Island, literature learning is integrated into Indonesian subjects, but the teachers there are more focused on teaching language using general literature rather than indigenous wisdom literature. Therefore, this study aimed to explore the situation and needs analysis of the indigenous wisdom-based literature in teaching Indonesian language at Buru Island. To achieve the objectives of the study, the researchers employed Research and Development (R&D) applying Borg and Gall’s steps. This method has certain procedures for the information collecting data related to the situation and needs analysis of 350 junior high school students through questionnaire distribution, interview, and observation toward the process of Indonesian teaching in the classroom. The situation of learning literature in the study involved (1) the law of local content learning, (2) curriculum, (3) syllabus, (4) lesson plan, (5) coursebooks, (6) teachers’ competence, and (7) stakeholders’ concerns, while, the students’ need analysis involved (1) current ability and interest in literature, (2) feedback of students’ ability and interest in literature, (3) literature skills priority, (4) learning style, (5) literature learning facilities and infrastructure, (6) literature materials on indigenous wisdom, (7) coursebook of indigenous wisdom-based literature, and (8) learning approaches and strategies based on indigenous wisdom. The result shows that there were still many shortages in implementing of indigenous wisdom-based literature learning in junior high schools, so students’ ability and interest were lack. Therefore, the situation and need analysis becomes very important to be explored and to be a consideration in designing course books in indigenous wisdom-based literature for the future.
