Shipboard laboratory index property data, shore-based consolidation tests, and in-situ stress and pore-pressure measurements are used in this study to constrain the stress conditions at ODP Site 808, Nankai Trough. Results of these tests are presented along with additional interpretations of porosity rebound and permeability. The sediment at Site 808 is highly affected by excess fluid pressures throughout the sediment column. Excess fluid pressure is severe below the major fault boundary, the décollement. The in-situ measurement of lateral stresses, which are shallow in the sediment section, confirms that the principal stress direction is rotated from a "normal" basin-type condition where the principal stress direction is vertical.

During Leg 125, scientists drilled three holes (782A, 784A, and 786A) in the Izu-Bonin forearc near 31° N that had sufficient recovery to obtain paleoinclination data. A total of 169 paleomagnetic samples were analyzed using either alternating field or continuous thermal demagnetization. Unfortunately, poor recovery, complex magnetization in the older sediments, and dipping beds prevented us from obtaining results that were older than middle Miocene. However, six reliable data points (one Pleistocene, three Pliocene, and two Miocene) were obtained. These data agree with past work from around the Philippine Sea plate, which suggest about 20° of northward translation since the Eocene. This paleomagnetic data set can be used to help constrain models for the origin and history of the Philippine Sea plate.
