Asperity distribution and earthquake occurrence in the southern Kurile Islands arc [PDF]

Physics of the Earth and Planetary Interiors, 1987
The seismicity in the southern Kurile Islands arc is characterized by a complex overlapping of aftershock zones of a few great and many large earthquakes (Ms ≧ 7.0). The spatial relationships of these aftershock zones can be explained in terms of a simple pattern of fault plane heterogeneity.
