B. GPSデータから推定されるバックスリップの分布 （石橋モデルの断層投影範囲より西の、遠州灘海域にバックスリップ量の大きな領域が広がる。）
Figure 3. Distribution of the back-slip in the Tokai district. Arrows and solid contours represent both direction and magnitude of back-slip at each point on the plate boundary. Dashed lines show depth contours of plate boundary configuration. Shaded area is Matsumura"s [1997] locked zone estimated from seismicity data.
