抄録	Large scale true polar wander episodes are considered to have occurred several times in Mars. Because they accompany relocation of the Martian equatorial bulge, milli-strain level horizontal extension/compression is expected to have occurred as well as kilometer scale vertical crustal movements. Here we pick up one of such episodes reported by Perron et al. (2007), and try to compare the expected strikes of faults with those observed in satellite images. Wrinkle ridges seem to have preferred orientations aligned with the meridian connecting the present and ancient poles, which suggests that some of those may reflect the crustal stress imposed by this true polar wander episode.
