Abstract The seismic focal process is controlled by two kinds of physical parameters: On the one hand, stable entities namely the tectonic-stress field, the dimensions of elastically reacting volumes, and the size and orientation of preexisting fractures; on the other hand, frictionlike processes which greatly influence the situation before an earthquake and the seismic dislocations. Because of the singular direction of fault movements the friction processes change in an irreversible manner. These continuously changing situations determine, however, the relationship between aseismic creep and seismic movements. The friction phenomena also determine the distribution of seismic dislocations on focal surfaces of different geometric area.
