Fig. 10.

The location of the Tohoku district of Japan and the seismogenic region off Tohoku. The rectangle indicates the seismic fault model used for the forward simulation and inversion analysis. Black arrows indicate the estimated slip deficit rate distribution by geodetic data inversion. Gray and white arrows indicate the horizontal velocity vectors at GPS stations relative to a reference point for the interseismic calm period 1996–2000 and those reproduced from the estimated slip deficit rate distribution. Solid lines connecting the GPS stations define the Delaunay triangles.
