Abstract
A method and apparatus for predicting the occurrence of an earthquake in a monitored area as described by detecting the vertical component of the Earth's magnetic field at a plurality of pairs of spaced points, the spacing 'd' between the points of each pair being from 450 to 2,300 meters in a first horizontal direction, the spacing 'Y' between each pair of points being between 450 and 25,000 meters in a second horizontal direction substantially perpendicular to the first horizontal direction.
