Fig. 12.

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