Abstract:
[Problem] To make it possible to accurately predict an earthquake on the basis of the average deformation distance of crustal deformation for each week at each electronic reference point. [Solution] The average deformation distance of crustal deformation over the period of a week is calculated for each electronic reference point. The average deformation distances of each of the latest four weeks for an electronic reference point for which the average deformation distance is equal to or greater than a threshold are compared with data from a database, and if, within a prescribed area, there is an electronic reference point having an average deformation distance that matches, within a range of approximation, said average deformation distances over a past consecutive period of four weeks, this past electronic reference point is extracted. If, after the consecutive period of four weeks, an earthquake of at least a prescribed magnitude that is considered to cause significant damage occurred at the past reference point within two weeks, information about the occurrence of the earthquake is provided as information about a latest predicted earthquake pertaining to an electronic reference value for which the average deformation distance over a latest prescribed period is equal to or greater than the threshold value. Further, if the latest calculated average deformation distance in the next prescribed period is greater than or equal to a prescribed threshold, the aforementioned operation is repeated.
