From: Analysis of plate spin motion and its implications for strength of plate boundary
Global geographical distribution of spin motion on a Mercator projection based on the plate model PB2002 (Bird 2003). The blue and green curved vectors represent clockwise and counterclockwise spin motion, respectively. The radius of the vector is correlated with the rate of spin motion. Black vectors indicate the directions of plate motions of the Pacific plate (PA), the Australia plates (AU), and the Nazca plate (NZ). The two letters with each vector identify the plate, AU Australia, EA Easter, JZ Juan Fernandez, KE Kermadec, NZ Nazca, NI Niuafo’ou, PA Pacific, TO Tonga
