Outline of Final Research Achievements

This study has derived effective parameters, which are available to detect precursory information leading to the prediction of great earthquakes, using observed GNSS data and numerical simulation of crustal movements. The parameters were comprehensively included in a software named “aPros-G” to construct a practical procedure for predicting the occurrence of great earthquakes. The software system uses both GNSS data of the F3 product and RINEX provided by the GEONET observation system. This study also has conducted numerical analyses of crustal movements simulating the interaction between the continental and sea plates based on the FEM technique. The analytical results were effectively used as a reference to construct the aPros-G system.
