In this activity, students use maps to plot a graph of earthquakes under New Zealand to show the shape of the North Island subduction zone and compare this to the distribution of earthquakes in the South Island.

By the end of this activity, students should be able to:

  • read a map legend to understand the distribution of earthquakes in New Zealand
  • use earthquake distribution data for plotting
  • gain an understanding of the subduction zone where the Pacific plate is plunging below the Australian plate
  • draw a simple sketch of what the plate boundary might look like at the bottom of the South Island.
