Показано, что землетрясение вызвало микробарические вариации в атмосфере, а также вариации магнитного и электрического поля на значительных расстояниях от очага сейсмического события. При этом возмущение магнитного и электрического полей зарегистрировано как в период основного толчка, так в период прихода в точку наблюдений инфразвукового сигнала, распространяющегося в атмосферном волноводе. Получено, что землетрясение привело к увеличению ошибки позиционирования GPS на эпицентральном расстоянии ~6008 км от очага землетрясения. Анализ результатов ионосферного зондирования, полученных на станции «Окинава», показал наличие ионосферного эффекта землетрясения в виде вариации критической частоты F2-слоя ионосферы. Приведенные данные в очередной раз демонстрируют влияние явлений и процессов, протекающих в литосфере, на атмосферу и ионосферу.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>We consider the results of instrumental registration of geophysical effects in the surface atmosphere caused by a strong 7.7 earthquake in Myanmar on March 28, 2025. It is shown that the earthquake caused microbaric variations in the atmosphere, as well as variations in the magnetic and electric fields at significant distances from the seismic event source. In this case, the disturbance of the magnetic and electric fields is recorded both during the period of the main shock and during the arrival at the observation point of the infrasound signal propagating in the atmospheric waveguide. It was found that the earthquake led to an increase in the GPS positioning error at an epicentral distance of ~ 6008 km from the earthquake source. The analysis of the results of ionospheric sounding of free access obtained at the Okinawa station showed the presence of the ionospheric earthquake effect in the form of a variation in the critical frequency of the ionospheric F2 layer. These data once again demonstrate the influence of phenomena and processes occurring in the lithosphere on the atmosphere and ionosphere. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>землетрясение</kwd><kwd>инструментальные наблюдения</kwd><kwd>акустический сигнал</kwd><kwd>электрическое поле</kwd><kwd>магнитное поле</kwd><kwd>критическая частота F2-слоя ионосферы</kwd><kwd>вариация</kwd><kwd>ошибка позиционирования GPS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>earthquake</kwd><kwd>instrumental observations</kwd><kwd>acoustic signal</kwd><kwd>electric field</kwd><kwd>magnetic field</kwd><kwd>critical frequency of the ionospheric F2 layer</kwd><kwd>variation</kwd><kwd>GPS positioning error</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования выполнены в рамках государственного задания Министерства науки и высшего  образования РФ (тема № 125012700798-8).</funding-statement></funding-group></article-meta></front><body><p> </p><p> </p></body><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
