(a) Map of the Tokai area. The Philippine Sea Plate is subducting in the NW direction beneath the Eurasian Plate. Dashed lines show depth contours of the plate interface (Noguchi, 1996; Nakamura et al., 1997). The vectors represent the total amount of slip that took place on the interface by 2009. The hypothetical source area of the anticipated Tokai earthquake is delineated by thick curves near the center (Central Disaster Management Council, 2001). (b) The accumulated seismic-moment release. The inverted triangles represent the times that gravity measurements took place in and around the Tokai slow-slip area.
