New GPS velocities in the Central Walker Lane record intracontinental transtension.

We model the GPS data with elastic blocks to estimate fault slip rates.

Shear accommodation via normal slip/block rotation is incompatible with GPS data.

Oblique or partitioned right-lateral slip is needed to release accumulating strain.
