Application of fractal methods for analyzing the microdeformation data of the Earth’s crust

The study examines variations in microdeformations of the Earth's crust using fractal and multifractal analysis methods. The main focus is on identifying patterns in the changes of fractal dimension and singularity power indices of data obtained with laser deformographs during periods preceding earthquakes. It was found that the fractal dimension increases prior to seismic events, especially for data from the laser deformograph located on a rocky base. The analysis demonstrated a decrease in amplitude and singularity power indices during active periods. The results confirm the potential of applying fractal methods for monitoring microdeformations of the Earth's crust and predicting earthquakes.
