Overview: Students read selections from the book "The Orphan Tsunami of 1700", by Brian Atwater, about earthquake and tsunami threats detected by scientific sleuthing in mud, trees, and the writings of samurai, merchants, and peasants. As they read, students look for evidence of the scientific process, connections between science and culture, and the role of technology in science.
Grade Level:
9 - 12
Objectives: Students will be able to:
  • Explain why studying earthquakes and tsunami are important
  • Describe what and where the Cascadia subduction zone is
  • Describe the process and evidence that scientists used to determine if the Cascadia subduction zone could cause large, destructive earthquakes
  • Describe how to detect and respond in case of earthquake or tsunami
  • Describe what areas of the world may experience the direct effects of subduction zone earthquakes and tsunami
