EARTHQUAKE PREDICTION METHOD BY SATELLITE POSITIONING

摘要

PROBLEM TO BE SOLVED: To solve problems for example, there are 1,200 or more of satellite positioning observation points called as an electronic reference point of the Geographical Survey Institute of the national land traffic ministry in Japan, thereby correct diastrophism is observed, it is possible to grasp the precursory phenomenon of relatively large magnitude of earthquake on the basis of a regulation of a distance connecting two points, or an area of a triangle connecting three points, but there are too many combinations of distances or triangles, so that it is difficult to select optimal distance and triangle.;SOLUTION: An event in which standard deviation of the maximum deviation exceeds a threshold value simultaneously is determined as precursory phenomenon of earthquake in a short period that the height of an ellipsoid is about one week among pieces of satellite positioning observation data in the satellite positioning observation points distributed in a finite area, for predicting earthquake.;COPYRIGHT: (C)2015,JPO&INPIT
