dc.description.abstract	Fractal and multi-fractal properties of the Earth’s magnetic field time variations caused by the earthquake took place on January 24, 2020 in Turkey were investigated. Using the Dynamical Fractal Analysis method proposed by the authors for both (D and H) horizontal components of geomagnetic field, the time dependences for the Hurst fractal dimension were obtained. With usage of the Wavelet Transform Module Maxima method and the Multi-Fractal Detrended Fluctuation Analysis method, the set of traditional and original multi-fractal numerical characteristics was estimated. Combining the fractal and multi-fractal analyses results with ones for the time-frequency structure, obtained the Continuous Wavelet Transform application, the set of disturbances caused by the earthquake was discovered. For these disturbances, all needed time-frequency, fractal and multifractal characteristics were estimated. The disturbances were shown to be fractal ultra-wideband processes with complex, non-stationary multi-fractal structure. Two promising candidates for the role of earthquake harbingers were revealed. One possible earthquake harbinger in both horizontal components of the geomagnetic field time variations seems to be detected. This harbinger was shown to be registered 25.5 hours before the earthquake event. Being be found in time variations of the multifractal characteristics only for both horizontal components of the geomagnetic field, another possible earthquake harbinger took place 0.5 hours before the earthquake event. The so-called transition of the multifractal process to the mono-fractal mode was detected. For both harbingers, the time-frequency, fractal and multifractal characteristics were estimated.
