Определить координаты очага землетрясения с минимально возможной ошибкой за счет оптимального выбора сейсмодатчиков. Метод. Для нахождения ошибок в определении гипоцентра землетрясения в зависимости от взаимного расположения трех сейсмодатчиков используются данные скоростей сейсмических волн, разности времен прихода сейсмических волн на сейсмодатчик и заданная ошибка в определении разности времен. По данным с ошибкой и без нее определяются два гипоцентра, разности которых и дают информацию об ошибке определения гипоцентра. Проведен анализ влияния взаимного расположения сейсмодатчиков и очага землетрясения на точность определения координат очага. Результат. Установлено, что для повышения точности определения координат эпицентра и гипоцентра землетрясения желательно использовать разные комбинации сейсмодатчиков. Даны рекомендации по их выбору с целью уменьшения ошибки в определении координат очага землетрясения. Получены зависимости ошибки в определении координат гипоцентра от взаимного расположения сейсмодатчиков и очага землетрясения в пространстве, при наличии ошибок в определении расстояния до гипоцентра землетрясения, как в сторону увеличения расстояния, так и в сторону уменьшения для всех сейсмодатчиков в различных вариациях. Для определения зависимости ошибки в определении координат очага от взаимного расположения трех сейсмодатчиков произведено перемещение третьего сейсмодатчика на горизонтальной плоскости по окружности с центром в начале координат. Вывод. При выборе сейсмодатчиков необходимо чтобы один из них был перпендикулярным центру отрезка, образованного между двумя другими сейсмодатчиками. Вероятность разнонаправленной ошибки измерения времени прихода волн тем выше, чем ближе расположены сейсмодатчики друг к другу и обусловлена тем, что сейсмические волны проходят близкие по расположению трассы.</p></abstract><trans-abstract xml:lang="en"><p>Objectives. To determine the coordinates of the seismic focus of an earthquake with a minimum margin of error with the use of an optimal selection of seismic sensors. Method. Seismic wave velocity data, relying on the time discrepancies between the registering of seismic waves on the seismic sensor and the defined error in determining the time difference, were used to identify errors in the location of an earthquake's hypocenter depending on the respective positions of three seismic sensors. Discrepancies between data containing an error and those without it used to determine two hypocenters provide information about the hypocenter locating error. An analysis of the influence of the respective arrangements of the seismic sensors and the earthquake epicentre on the accuracy of determination of epicentre coordinates was carried out. Results. It is established that, in order to improve the accuracy of epicenter and hypocenter earthquake coordinate determination, it is preferable to use different combinations of seismic sensors. The present recommendations are based on the desire to reduce errors in determining the earthquake source coordinates. Due to earthquake epicenter distance determination errors found in different seismic sensors both with increasing and decreasing distance, the hypocenter coordinate determining error has been found to depend on the respective arrangement of seismic sensors and on the earthquake source's geographical location. In order to determine the dependence of the source coordinate determining error on the relative position of three seismic sensors, the third seismic sensor was displaced on a horizontal plane at the location centered at the coordinate of the origin. Conclusion. When selecting seismic sensors it is essential that one of them be located perpendicular to the center of the segment formed by the other two seismic sensors. The probability of a multidirectional error of measurement at the moment of arrival of seismic wave is higher the closer the seismic sensors are to one another; this is due to the fact that seismic waves pass close by the trajectory layout.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>землетрясение</kwd><kwd>сейсмодатчик</kwd><kwd>сфера</kwd><kwd>ошибка</kwd><kwd>уравнение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>earthquake</kwd><kwd>seismic sensor</kwd><kwd>scope</kwd><kwd>error</kwd><kwd>equation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шахриманьян М.А., Нигметов Г.М., Сосунов И.В.
