Continuous GPS array of Japan and its application to crustal activity modeling

A continuous GPS array is a very useful tool for monitoring and modeling crustal activity. GPS observation has revealed various unknown aspects of tectonic deformation in Japan and other locations. Quasi-real time data acquisition and dense spatial coverage enable incorporation of GPS data into simulation models for crustal activity forecast, which is similar to data assimilation in weather forecast. For that purpose, it is important to develop new techniques of geodetic inversion and time series analysis
