Search of the operational earthquake precursors on the basis of the identification measurements of the seismographic records

The applicability of the identification measurements of seismographic records for the formation of the informative parameters of their analysis is shown in this paper. The type of identification parameter is experimentally defined which change is connected with a distribution structure of the seismographic records reading. The computer device was created realizing the seismographic records analysis with the instruments of identification measurements. The method for determination of the earthquake precursors is offered which is based on the consecutive comparison of an identification S-parameter changing as approaching the earthquake moment with some of its threshold value. The seismographic records analysis with the various forces of earthquakes allowed establishing the threshold value of S-parameter in the expert way for the operational forecast of earthquakes.
