Using slinkies to show how earthquakes produce body and surface waves

The new ELI today is 'The slinky seismic waves demo; using slinkies to show how earthquakes produce P-, S- and surface waves'.

In this activity, two slinky springs are used to show how one earthquake produces P-, S- and surface waves. It can be difficult to understand how one sudden movement along a fault plane at the underground focus of an earthquake can cause three different sorts of earthquake waves with different properties.
Many more activities about earthquakes can be found on our website.
