Evidence supporting the seismokinetic origin of the variations in the vector magnetometer was the discrepancy between the total magnetic field measured by the absolute magnetometer and the total magnetic field calculated from the vector magnetometer readings. Equations were derived that relate variations in the components of the magnetic field to the tilt angles of the sensor, enabling the determination of the direction of arrival of seismic shock waves. Azimuths of earthquake epicenters were calculated from oscillations observed in magnetogram records for several events, and these were compared with azimuths obtained from a network of seismic stations. It is shown that, in order to improve the accuracy of geomagnetic field measurements\u2014required for the study of seismoelectric and seismomagnetic phenomena, as well as for identifying earthquake precursors\u2014the design of magnetic observatories should be supplemented with an inclinometer to enable correction of vector magnetometer measurement results.<\/jats:p>","DOI":"10.3390\/s26134239","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T15:15:04Z","timestamp":1783091704000},"page":"4239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Method for Identifying Seismokinetic Effects in Earth\u2019s Magnetic Field Measurements"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6216-0443","authenticated-orcid":false,"given":"Ivan","family":"Vassilyev","sequence":"first","affiliation":[{"name":"Special Design and Technology Bureau \u201cGranit\u201d, 292 Hussainov Street, Almaty 050060, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir","family":"Saveliev","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3818-404X","authenticated-orcid":false,"given":"Zhassulan","family":"Mendakulov","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0416-6724","authenticated-orcid":false,"given":"Vadim","family":"Lutsenko","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9996-4050","authenticated-orcid":false,"given":"Linara","family":"Zhadigerova","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3507-913X","authenticated-orcid":false,"given":"Andrey","family":"Malimbayev","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0085-5802","authenticated-orcid":false,"given":"Botakoz","family":"Seifullina","sequence":"additional","affiliation":[{"name":"Institute of Ionosphere, 117 \u201cIonosphere\u201d Gardening Association, Kamenskoye Plateau, Almaty 050020, Kazakhstan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jelena","family":"Caiko","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science, Information Technology and Energy, Riga Technical University, 12\/1 Azenes Street, LV-1048 Riga, Latvia"},{"name":"Natural Sciences and Information Technology Department, Riga Nordic University, 1 k-5 Valerijas Seiles Street, LV-1019 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,3]]},"reference":[{"key":"ref_1","unstructured":"Shroder, J.F., and Wyss, M.
