Abstract
This report presents the results of a detailed analysis of the variations in geomagnetic parameters on the eve and during the strong earthquake of November 25, 2016 (M=6.4) that occurred in the border area of Tajikistan, China and Kyrgyzstan. To assess the state of the geomagnetic field, the data of the geomagnetic observatory “Alma-Ata”, the international code – AAA; geographical coordinates [43.25°N; 76.95°E]; geomagnetic coordinates [34.3°N, 152.7°E]. A detailed analysis of the variations of the seconds values of the X-, Y-, Z-components of the geomagnetic field showed that sinusoidal oscillations with periods of the order of 52–55 minutes appear before the earthquake in variations of the geomagnetic field.
