1. An earthquake prediction method comprising:

  • observing magnetic field vectors of magnetic fields within an observation area;

    estimating telluric current induction field vectors and telluric currents based on vector differences between the observed magnetic field vectors and a geomagnetic vector;

    collating and comparing a change over time of the estimated telluric currents and a state of the estimated telluric currents within the observation area, with past patterns of change over time of telluric currents and a state of the telluric currents; and

    estimating a seismofocal zone, time of occurrence, and seismic intensity of a seismic event based on the comparison.
