Unit Objectives:

  • Compare the characteristics and behaviour of the two types of seismic body waves
  • Summarize the variations in seismic-wave velocity as a function of rock type and temperature and pressure conditions
  • Explain how the principle of elastic deformation applies to earthquakes
  • Describe how the main shock and the immediate aftershocks define the rupture surface of an earthquake, and explain how stress transfer is related to aftershocks
  • Explain the process of episodic tremor and slip
  • Describe the relationship between earthquakes and plate tectonics, including where we should expect earthquakes to happen at different types of plate boundaries and at what depths
  • Distinguish between earthquake magnitude and intensity, and explain some of the ways of estimating magnitude
  • Explain the importance of collecting intensity data following an earthquake
  • Describe how earthquakes lead to the destruction of buildings and other infrastructure, fires, slope failures, liquefaction, and tsunami
  • Discuss the value of earthquake predictions, and describe some of the steps that governments and individuals can take to minimize the impacts of large earthquakes
  • Explain some of the ways that seismic data can be used to understand planetary interior
  • Give evidence for the fact that the earth is layered
  • Diagram or model the interior of the earth, labeling all principal parts and showing the approximate thickness of each layer
  • Differentiate among the layers of the earth and describe their characteristics
