WebbInterplate volcanoes are located at active plate boundaries created by volcanism at mid-ocean ridges, subduction zones, and continental rifts. The prefix “ inter-“ means between. Some volcanoes are intraplate volcanoes. The prefix “ intra-“ means within, and intraplate volcanoes are located within tectonic plates, far removed from plate boundaries.
