Аннотация:The three-dimensional geomechanical model of Southern California was developed including
a mountain relief, fault tectonics and internal border characteristics such as the roof of the
consolidated crust and Moho surface.
During the last six years on the basis of the developed geomechanical model and current
seismicity is realized an approbation of technology for the estimation of possible future
seismicity on a two weeks interval. All four strongest events with М ~ 5.5–7.2 occurred in
South California during the analyzed period were prefaced by the stress anomalies in peculiar
advance time of weeks-months.
Inside the stress state background level investigation it was identified the feature of the largescale
interaction between two seismically active tectonic provinces of Southern California.
