METHOD FOR SHORT-TERM EARTHQUAKE PREDICTION Russian patent published in 2011 - IPC G01V1/00 

FIELD: mining.

SUBSTANCE: lithospheric build-up waves of earthquake focus are measured by means of autodyne metres in mode of mutual synchronisation, which are arranged on mutually orthogonal measuring bases. At that, warning signal is extracted by frequency detection of carrier frequency of autogenerator. Vector length of movement direction of lithosphere plate at the focus build-up is calculated through its projections on orthogonal bases. Change of length of the above vector and law of change of oscillation period of amplitude of the resultant signal in time is monitored. Earthquake probability distribution function is obtained due to relative change of the above period. Time of warning signal and shock magnitude is calculated. Then, in compliance with orientation of measuring bases, the vector line of lithosphere plate movement is applied to ground map. Probability of seismic shock on vector line is determined as per density of distribution of probabilities.

EFFECT: improving determination accuracy of seismic shock parameters; increasing the time of warning prediction.
