Measurements of surface displacements using GPS constrain the motion and deformation of India and India-Eurasia plate boundary deformation along the Himalaya. The GPS velocities of plate-interior sites constrain the pole of the angular velocity vector of India with respect to Eurasia to lie at 25.6¿1.0 ¿N11.1¿9.0 ¿E, approximately 6¿ west of the NUVEL-1A pole of <3 Ma plate motion. The angular rotation rate of 0.44¿0.03¿ Myr-1 is 14% slower than the long-term rate of 0.51¿ Myr-1. Insignificant velocities between plate interior sites indicate that the exposed Indian plate is stable to within 7⋅10-9 yr-1. The observed contraction vector across the Himalaya (≤20 mm/yr) veers from ~N20 ¿E in the northwest Himalaya to ~N25 ¿W in east Nepal, consistent with east-west extension of southern Tibet. ¿ 2001 American Geophysical Union
