The paper considers quantitative relationships between the length of seismogenic rupture, displacement, and magnitude of earthquakes as a function of slip geometry and regional stress field. These relationships differ for faults of the same geometry (normal, reverse, or strike-slip) formed in different lithospheric stress fields. Strike-slip faults are the most universal seismogenic ruptures. Their parameters show a close relationship with earthquake magnitudes in any stress field. Normal and reverse faults formed under extension and compression, correspondingly, or in transitional fields show most regular relationships of their parameters. Zones of compression are the most complicated settings for faulting with any slip type. The results of these studies are important for reconstructions of paleoseismicity.
