The probability density functions (PDFs) of earthquake energy fluctuations at different times have fat tails with a q-Gaussian form. We analyze the PDFs of energy fluctuations for different faulting styles and the relationship between the deviation from the Gaussian distribution and the faulting style. There are common features between the b-value and q-parameter dependence on the faulting styles. We suggest that the deviation from Gaussian distribution for the PDFs of earthquake energy fluctuation may be a useful indicator in earthquake-hazard research.
