REAL-TIME METHOD OF FORECASTING PLACE BRACING FOR EARTHQUAKE Russian patent published in 2009 - IPC G01V7/10 

FIELD: physics; measurement.

SUBSTANCE: present invention pertains to real-time methods of forecasting earthquakes and can be used in monitoring systems and processing data from geophysical measurements. On at least each of three seismic stations, a pair of gravitational variometers similar to multi-lobe sensitivity diagrams, is installed at an angle to each other, which is not a multiple of 90°, and oriented in cardinal directions with initial angles of orientation. When the position of the beams of gravitational variometers is changed, the change in angles is determined, relative their initial angles of orientation with subsequent determination, from the diagram, of sensitivity and the change in the angle of orientation of each device directed at the centre of imminent earthquake. The location of the centre is determined through intersection of directions at this position, obtained from at least seismic stations.

EFFECT: more accurate forecast.
