Velocity profile across the NCSZ. Plotted velocities show a component perpendicular to the profiles. a Velocities along profile A–A′ from April 2005 to December 2009. Red and blue curves are calculated velocities of elastic dislocation models for a vertical strike slip fault with a creeping rate of 4 and 6 mm/year, respectively. b Same as a but from July 1997 to June 2000. But profile B–B′. c Velocities along profile B–B′ from April 2005 to December 2009. d Same as c but from July 1997 to June 2000. e Velocities along profile C–C′ from April 2005 to December 2009. f Same as c but from July 1997 to June 2000
