Abstract: Abstract In-depth studies of large earthquake rupture characteristics are crucial for understanding earthquake physics, the Earth system, and mitigating seismic risks. Characterizing static complex slip distribution on fault rupture surfaces remains a key unsolved issue in seismology. Advances in source process inversion techniques have yielded abundant static slip data over recent decades. This paper reviews recent progress, introduces five models for characterizing slip distribution patterns, and evaluates their performance. Results show the power-law decay model performs best, while the homogeneous model performs worst. These findings may enhance seismic risk assessment and real-time disaster mitigation strategies.
