Figure 2. (WWW-version) Bathymetric map of the Nankai margin south of Shikoku showing the location of the 1999 3-D seismic survey (green rectangle), proposed primary (red stars and labels) and secondary (pink stars and labels) Leg 190 Eastern Nankai Trough drill sites, Site 808 (yellow square), and Line 141-2D. Primary sites are indicated by larger site numbers.
Figure 3. (A) Line drawing interpretation of seismic Line 141-2D. (B) Interpreted cross section showing location of proposed Leg 190 sites. Primary sites are in bold.
Figure 4. Correlation between seismic data and porosity at Site 808, ODP Leg 131 (after Taira,
Hill, Firth, et al., 1991; Taira et al., 1992).
Figure 5. Regional seismic reflection line across the toe of the western Nankai Trough (WNT) accretionary prism showing locations of previous Deep Sea Drilling Project (DSDP) drill sites and proposed alternate Leg 190 sites in the WNT. PTZ = proto-thrust zone.
