A Fractal Analysis of Earthquakes in West Taiwan

Abstract

The fractal dimension is calculated for earthquakes in west Taiwan. The correlation integral algorithm proposed by Hirata et al. (1987) is used to estimate the values of fractal dimensions for earthquakes in two parts, separated approximately by the latitude of 24¢XN in west Taiwan. Results show that the fractal dimension value (1.304 +-0.002) for northern events is less than the value (1.599 +-0.002) for southern events. This indicates that northern events are more heterogeneous than southern events. Besides, the fractal dimension is negatively correlated with the b value.
