Аннотация

In a detailed analysis of the local features of the stress-strain state within the framework of the geomechanical model of Southern California, a rapidly developing high-amplitude shear deformation anomaly was identified in the upper crustal interval (at depths of up to 10 km) – the so-called “intense deformation quantum” – with a maximum increase in deformation by two orders of magnitude within 0.5 month. Such “quanta” can be integral elements of the entire deep deformation process associated with seismicity. The paper discusses the quantitative characteristics of deep deformation “quanta” and the conditions for their occurrence.
