Scaling organization in the dynamics of blocks-and-faults systems

Some elements of the model of scaling organization of fracture tectonics (SOFT) are incorporated into the model of block structure dynamics (BSD). The resulting new model permits to obtain a power law relationship between earthquake energy and fault area with an exponent 3/2, as for observed seismicity. This is an important advantage of the new model in comparison with the BSD model, in which this dependence is generally linear.
