METHOD OF SHORT-TERM EARTHQUAKE FORECAST Russian patent published in 2008 - IPC G01V9/00 

FIELD: physics.

SUBSTANCE: method for short-term earthquake forecast includes registration of seismic background waves in two distanced points of base, registration of time when regular component of infrasound signal appears, defining fractal magnitude of amplitude-frequency response of the component, tracking time history of fractal magnitude, calculation of dynamic process time constant (T), forecast of expected shock characteristics: shock time t_y=4.7 T, shock magnitude lg t_y[day]=0.54 M - 3.37, hypocentre as cross-point of sight lines drawn from the base direction at angles where B_x1(0), B _y1(0) are autocorrelation function values for signals at zero point on the planes (x, y) of first seismic receiver; B_x2(0), B_y2(0) are autocorrelation function values for signals at zero point on the planes (x, y) of second seismic receiver.

EFFECT: extension of earthquake forecast interval to 4 hours.
