Discussion

Systematic analysis reveals regional variability in earthquake source parameters, suggesting implications for seismic hazard assessments.

Earthquake source parameters show significant regional variability, impacting seismic hazard assessments.
The analysis involved over 6200 earthquake recordings, focusing on moment magnitudes from 3.1 to 6.6.
Assessment of earthquake source parameters was based on a new Fourier spectral attenuation model developed for Australia.
Findings highlight the utility of derived parameters for national-scale ground-motion models and regional studies.

Trevor I. Allen (2025) studied this question.
