Outline of Final Research Achievements

We developed the prototype system of rapid coseismic fault model estimation for the large earthquake whose magnitude is more than 7 based on real-time GNSS and strain meter. We showed the method for the high precision kinematic GNSS analysis and investigated the precision of kinematic GNSS time series using developed precise movable table for GNSS antenna. We also investigated the uncertainties estimation of the rapid coseismic fault model estimation using GNSS data based on MCMC approach. Furthermore, we improved the method for rapid coseismic fault model estimation based on borehole strain meter. Finally, we have started operation the prototype system of the distribution and its analysis of crustal deformation continuous observation data.
