In this activity, students explore tectonic movements called slow slips. They plot and interpret a graph using data from an actual event in New Zealand.

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

  • understand the difference between earthquakes and slow slips
  • plot and interpret data on a line graph
  • explain a scientific application of GPS technology.
