  • hot spots
    • where plumes of magma are rising from the asthenospher
      • not necessarily near a margin
      • weak crust= volcanic eruption
        • build up of lava= volcanic island
    • CASE STUDY
      • Hawaiian Islands
        • volcanic islands
        • As the pacific plate has moved north, the volcanoes have too
        • earthquakes
          • movement of the Pacific plate across the islands is not smooth
