Global Positioning System (GPS) data from experiments conducted in 1985 and 1989 in the southern Gulf of California, Mexico, allow a determination of relative motion between the Pacific and North American plates. The data indicate motion of Cabo San Lucas on the Pacific plate relative to North America at a rate of 47±7 mrn/yr and azimuth of 57±6° west of north (1σ errors), equivalent within uncertainties to the NUVEL‐1 global plate motion model.
