... phenomena. Its complexity can be described by a fractal behavior in both space and time. For aftershocks, the quantity of small and large events are related by the Ishimoto-Iida/Gutenberg-Richter law ( Ishimoto and Iida, 1939 ; Gutenberg and Richter, 1944 ). The temporal distribution of aftershocks often...

...Mamoru Kato Abstract Frequency distribution of the maximum amplitude of seismograms at a station exhibits a power‐law relation, which is the Ishimoto–Iida law (II law). We investigate whether the II law is applicable to modern strong‐motion seismograms. Distribution of maximum amplitudes records...

.... The slope is the same for Tonga-Fiji for all depth ranges. In this paper, the frequency of occurrence of earthquakes in relation to their size is investigated for different individual tectonic units. The magnitude versus frequency relation was first investigated by Ishimoto and Iida (1939) and later...

... that can be traced back to Ishimoto and Iida's empirical power law formula in 1939 describing the frequency of maximum amplitudes of observed seismic waves. The G-R relationship is unambiguously defined by a simple formula, but some ambiguities about the G-R relation exist as well. For example, possible...

The coefficients k and m are to be determined. For a, it is sufficient to consider the maximum...
