Processing and Solutions

Distribution of GEONET GPS stations used for the processing of Tohoku-oki earthquake on March 11, 2011.

Seismic Wave and Co-Seismic Deformation
Seismic wave and co-seismic deformation for Tohoku-oki earthquake estimated with GPS for GEONET station 0037. Coordinate solution in PPP kinematic processing does not affect "reference station" in baseline processing, and the information can be used for fault modeling of the earthquake directly.
