Time series data of strong, large (EV1) and weak, small (EV2) two earthquake events were analyzed by dividing them into three different regions. Fractal dimensions of the EV1 and EV2 were produced using the box-counting algorithm for east-west (BHE), north-south (BHN), and vertical (BHZ) components. The small, weak earthquake, EV2, created a larger fractal dimension in phase space by implying its random nature in all regions. However, EV1 is a strong, large earthquake that presents deterministic oscillatory behavior at a long-time region. Oscillatory behavior can be named surface wave. EV2 exhibits weak, high-frequency ground oscillations similar to fibrillation before and after the earthquake in the long-term areas.eninfo:eu-repo/semantics/closedAccessFractal DimensionTemporal VariationsB-ValueSeismicityGeometryFractal DimensionTime SeriesTemporal VariationsPhase SpaceB-ValueFractalsSeismicityChaotic DynamicsGeometryRandom ProcessArticle4559134WOS:00106871330000410.26830/symmetry_2023_1_045N/AQ1
