Lithospheric stress field as a control over seismogenic fault parameters and earthquake magnitudes

The paper considers quantitative relationships between the length of seismo genic rupture, displacement, and magnitude of earthquakes as a function of slip geometry and regional stress field. These relationships differ for fau lts of the same geometry (normal, reverse, or strike-slip) formed in differ ent lithospheric stress fields. Strike-slip faults are the most universal s eismogenic ruptures. Their parameters show a close relationship with earthq uake 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 t he most complicated settings for faulting with any slip type. The results o f these studies are important for reconstructions of paleoseismicity.
