Preliminary analysis of the self-similarity of the aftershocks of the Japanese earthquake on March 11, 2011

The quantitative parameters of the self-similarity of the aftershocks of the Japanese earthquake on March 11, 2011 were obtained. The parameters p in the Omori law (1.06), b in the Gutenberg-Richter law (0.61), and the fractal dimension (D) of the earthquake epicenters (1.52) were determined. Self-similarity is manifested in a range of two orders of temporal and spatial scales and four units of magnitude. The stability in time of parameter p and spatial variations in b and p parameters were revealed.
