In this activity, students are introduced to some of the methods scientists use to record earthquakes. They obtain data from tables and graphs, carry out simple calculations and draw results on a map.

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

  • use seismograms from three recording stations to locate the epicentre of an earthquake
  • measure the difference in arrival time of P-waves and S-waves, and read the distance from epicentre from a graph
  • plot the epicentre location on a map
  • investigate the area affected by the earthquake
  • write a report that includes a prediction of possible damage, based on type of landscape, human and environmental features.
