METHOD FOR SHORT-TERM PREDICTION OF LOCAL MAGNITUDE OF EARTHQUAKE Russian patent published in 2015 - IPC G01V9/00 G01V1/00 

FIELD: physics.

SUBSTANCE: method includes calculating a Fourier spectrum from waveforms of external earthquakes detected by two seismic stations, wherein one of the stations, which is close to the earthquake hypocentre, is called the input station and the other, which is located at the point of estimating tension in the earth environment, is called the output station; calculating the quasi-amplitude-frequency characteristic of the earth environment at the location of the output station, as well as two criteria therefrom: integral and fractional-integral; deducing an imminent earthquake from observing a sharp decrease in the values of the integral criterion and a sharp increase in the values of the fractional-integral criterion; predicting the local magnitude of the imminent earthquake from the maximum value of the fractional-integral criterion, wherein the local magnitude is predicted using a calibration curve of local magnitudes of earthquakes plotted in advance for a specific pair of stations from values of the fractional-integral criterion.

EFFECT: short-term prediction of the local magnitude of an earthquake.
