| 内容記述 | From the relationship between temporal changes of gravity and leveled heights in tectonic region, a new practical equation for detecting temporal change in orthometric height, which provides unstable modes of vertical crustal movement in a special case, i.e., growing gravity-induced orthometric height decay instability is presented. This instability generates at the time of the maximum growing geoid level so as to stabilize the geopotential in the area and to regulate further crustal upheaval and returns from the high unstable level to the initial linear stable level, generating the earthquakes around the zone of increasing geoidal undulation. By making some assumptions to solve this equation, unstable fluctuation mode and strong instability mode were estimated to occur with periods of 15-17 years and 44-46 years, respectively, basing on the 7-8 year phase difference of crustal deformation under the assumption of the earthquake recurrence period of 117 years in the Nankai-Tokai zone. It is pointed out that the occurrence mode of the large anomalous crustal deformation, which may be related to the great earthquake, can be, conversely, estimated by the sequential mode analyses from these superposed instability modes within a few years deviation. | |||||
