 The westward propagating and slowly diverging Cocos-Nazca Ridge cuts between the two sub-plates toward the East Pacific Rise.However, the tip of Cocos-Nazca Ridge does not fully meet the East Pacific Rise and, in fact, the westerly propagating Cocos-Nazca Ridge generates secondary transient rifts by shear stresses.The tip of the Cocos-Nazca ridge has maintained a distance of 50 km from the East Pacifc Rise and slightly moved its position into the eastern part of the microplate due to clockwise rotation of the GMP.
