Abstract

By analyzing the seismicity in natural time and studying the evolution of the fluctuations of the entropy change of seismicity under time reversal for various scales of different length i (number of events), we can identify the approach of a major earthquake (EQ) occurrence. The current investigation is extended from 1984 until now for the seismicity in Japan.
