Seismic monitoring equipment around the world allows us to map the location and size of earthquakes as they occur, enabling us to predict the probable impact of future earthquakes. The pattern of the internal structure of the Earth, tectonic plates, and three main types of plate boundaries are all shown graphically.
Students should create annotated diagrams showing the structure of the earth and tectonic movement leading to an earthquake, concentrating on correct use of terminology. Research where significant earthquakes have occurred in the past, then compare to a map of tectonic plates, to see the correlation. Discuss the role of monitoring earthquakes, considering how it works, who funds it and who it can potentially help. Explain how the Richter scale is measured using a seismograph and ensure that students have an understanding that this is an exponential scale.
