space geodesy%North Hemisphere%compression%Euler parameter
The convergent and divergent velocities of active plate boundaries in the North Hemisphere are obtained with space geodetic data. The relative motions of adjacent plates in north-south direction are almost convergent; the spreading rates of the north mid-Atlantic ridge are smaller than the south mid-Atlantic ridge; the closed differences of the baseline length rates between stations on different plates along the latitudinal circle of 7.7(, 23.3o, 34.8o, 42.0o and 51.0o are all negative. All these show that the North Hemisphere is a compressive hemisphere.
