Abstract

The paper investigates the dynamics behavior of earthquake occurences by using the framework of nonlinear and chaotic systems. The phase space reconstruction approach is used to analyze chaotic time series of earthquake occurrences in Bali and the surrounding region. In addition, the calculations of fractal geometry are performed in the distribution of space and time. The large fractal dimension related to seismicity in space dimension indicates a random distribution of earthquake occurrences and associate with irregular geometry. While in time series, fractal patterns can be used as reference in earthquake preparedness and hazard mitigation. The results show that earthquake behavior has characteristic of deterministic chaos and varying the value of fractal.
