Identification of earthquake precursors by signals of seismic activity via the method of information-entropic analysis

Abstract

We have studied singularities of seismic time series for the periods before, during and after the earthquakes due to search their precursors. We have used the new methods for analysis of chaotic signals developed in nonlinear physics. It was shown that entropy of a part of seismic signals increases in comparison with quiet periods before all earthquakes under examination observed in our region. It is necessary to notice that the increasing of entropy is relatively small for earthquakes with small magnitudes, and growths with increasing of magnitude of an earthquake. The studies were fulfilled on the basis of data provided by the Seismological experimental-methodical expedition of CS MES of RK.
