To make accurate earthquake prediction possible on the basis of average fluctuation distance of crustal deformation of each week of each electronic reference point.SOLUTION: The average fluctuation distance of one week of crustal deformation is calculated for each electronic reference point, and for each electronic reference point whose average fluctuation distance is equal to or larger than the threshold value, the average fluctuation distance of the latest 4 weeks is stored If there is an electronic reference point whose average variation distance coincides within the approximate value range for a past consecutive 4 weeks in a predetermined area within the predetermined area, it extracts the electronic reference point, Earthquake occurrence within 2 weeks that is considered to cause serious damage to the earthquake occurrence information, the earthquake occurrence information is compared with the electronic reference value in which the average variation distance in the predetermined period is equal to or more than the threshold value recently, Provide as recently expected earthquake information. Furthermore, when the average fluctuation distance recently calculated in the next predetermined period is equal to or more than the predetermined threshold value, the above operation is repeated.(FIG.
