These videos are also used in the lesson plan Stressed Out! (grades 9-12).
An earthquake is caused by a sudden rupture or movement in the earth’s crust, usually due to the release of tectonic stresses which have accumulated over time. Seismic waves radiate from an earthquake’s epicenter as energy from the rupture is transferred and dissipated through the earth. When this rupture occurs underwater, water is also displaced, creating massively destructive waves called tsunamis. These clips from the NATURE episode “Can Animals Predict Disaster?” examine the tsunami of December 26, 2004. They challenge students to theorize about how animals’ greater sensitivity to seismic waves might have given them a lifesaving warning about the disaster which claimed over a quarter million human lives.
Suggested Focus Questions:
Clip 1: Destructive Forces
- What are some possible historical instances of animals fleeing an upcoming natural disaster?
- What might be some explanations for these flights?
Clip 2: Waves of Destruction
- What causes a tsunami?
- Why would the seismic waves traveling though the earth move so much faster than the tsunami’s waves of water?
