Slip vectors of multiple orientations on a single fault surface may be explained by the interaction of crustal-scale faults in response to nearby earthquakes. Field observations of at least five sets of striae on a single planar fault surface can be reproduced in numerical experiments. These experimental results suggest that slip vectors having variable orientations may reflect a highly transient local stress state in an otherwise constant regional stress field. Our results suggest that stress-inversion techniques should be applied with caution to areas with complex regional-scale fault patterns.
