Or, by using the Mercalli scale
Activate: What is the difference between the richer scale and the

• Under your copy of the diagram complete the sentences by filling in the correct definition.
• Measures the intensity of an earthquake by taking the numerical scale of movement recorded onto a seismograph during an earthquake.
• Measures the intensity of an earthquake according to the perception people have of how severe the earthquake is by the damage it causes.
• Extension: Which scale do you think is a more accurate way of measuring earthquakes? Why do you think this?
Demonstrate: How can the seismographs be used to create a
living graph?
Living Graph Activity
• Analyse the seismograph reading from an earthquake.
• Read the statements about what might happen before,
during and after an earthquake.
• Decide where you think the statements should go on the
graph.
• Pick 3 of the statements and write a description to explain
why you have put them in this location.
