Popis: Analysis of aftershock sequences of the strongest earthquakes of the world showed that previously discovered empirical relations are not universal. Bath’s law is found to be invalid in the majority of cases, while Omori’s law is valid only in a short initial interval of aftershock activity. It is supposed that aftershocks of the strongest earthquakes of normal depths are related initially to fracture of zones that preserved their integrity after the rupture in the source of the main shock and at a later stage to relaxation of stresses in the medium adjacent to the rupture.
