the macquarie triple junction is a geologically active tectonic boundary located at at which the indo-australian plate, pacific plate, and antarctic plate collide and interact. the term triple junction is given to particular tectonic boundaries at which three separate tectonic plates meet at a specific, singular location. the macquarie triple junction is located on the seafloor of the southern region of the pacific ocean, just south of new zealand. this tectonic boundary was named in respect to the nearby macquarie island, which is located southeast of new zealand.
