METHOD OF PREDICTING EARTHQUAKE AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2012 - IPC G01V3/08 

FIELD: physics.

SUBSTANCE: invention relates to geophysics and can be used for rapid prediction of the epicentre of an expected earthquake. The geomagnetic field is locally compensated for by generating a compensation magnetic field with opposite intensity to that of the geomagnetic field. Spontaneous disruption of the compensated magnetic field is monitored. An earthquake precursor is indicated by onset of said disruption and the emergence of an additional component of magnetic field intensity which disrupts local compensation of the geomagnetic field. Upon detection of an earthquake precursor, direction finding of the epicentre of the expected earthquake is carried out from several spaced apart observation points on the direction of the vector of the additional component of magnetic field intensity. The apparatus for realising said method is in form of a compass with a magnetic needle (3) and an azimuth scale (2), capable of adjustment rotation. The housing (1) of the compass is mounted on posts (5, 6) of a base (7). A rotating platform (8) is also mounted on the base (7). A circular wire loop - solenoid (21) is also mounted on the posts (15,16) of the rotating platform (8) with possibility of adjustment rotation around a diametrical horizontal axis and, together with the rotating platform (8), around a vertical axis. The centre of symmetry of the solenoid (21) coincides with the centre of the magnetic needle (3) of the compass and its diameter is much greater than the length of the magnetic needle (3). The solenoid (21) is connected into an electric circuit having a stable current source, a current direction inverter, a switch, a normally closed button and a current regulator.

EFFECT: rapid prediction of the epicentre of an approaching earthquake.
