GPS data can be used to track the rate and direction of plate movement. If a GPS unit measures a latitude velocity of 28.2 mm/yr and a longitude velocity of 59 mm/yr, what is the velocity of plate motion?

Answer and Explanation:

Rate and direction of plate movement obtained by using a latitude velocity of 28.2 and a longitude velocity of 59 then velocity of plate motion.

latitude velocity of 28.2 mm/yr

longitude velocity of 59 mm/yr

velocity = s/t but ib calculation GPS using formula where

a = sin² (Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin² (Δλ/2)

c = 2 * atan2 (√a, √ (1-a))

d = R * c

then velocity of plate motion is 65.4 mm/yr
