Figure F8. RAB image of breakouts (dark low-resistivity parallel lines down image) at 460505 mbsf in Hole 808I showing images at 1-in (shallow), 3-in (medium), and 5-in (deep) penetration from the borehole. This image is ~100 m below the frontal thrust zone, close to the base of logging Unit 2. The breakouts indicate the orientation of the minimum horizontal compressive stress (2) ~northeast-southwest, which is in good agreement with the plate convergence vector of ~310314the maximum compressive stress, 1 (902).
