Terry in the Black Hills of South Dakota, where he goes to relax now and then. Frame from a video of my Parkfield Earthquake Model Former Graduate Student Bill Power posing by one of the fault surfaces he measured the roughness of, Dixie Valley, Nevada. The top one was sheared to 18 mm, the bottom one to 60 mm. The distributed shear strain accounts for about 9 mm of the slip. The remaining slip occurs on localized boundary-parallel surfaces near the bottom boundary.
