Tsunami Review Sheet
What is a tsunami wave? How does it differ from a normal wind-driven wave? Why are the terms "tidal wave" and "seismic sea wave" not good names to describe a tsunami wave?
Define the following properties of a wave: wavelength, frequency, amplitude, velocity. Compare and contrast each of these properties for wind driven waves and tsunami waves (both open ocean and near shore).
Why are tsunamis not detectable in deep water?
Review Figure 15.8. Describe the motion of water as a wind driven wave passes.
List and explain the four ways that tsunamis can be generated.
Why do landslides and impact generate the largest tsunami waves?
What type plate boundary is most likely to generate a tsunami? Why?
Review figure 7.18 in your text. Explain why the amplitude of a tsunami increases when it approaches the shore line.
Describe the following stages in tsunami development: down draw, run up and reflection.
What is the weight of a cubic meter of water? Bedside the force of water, what else can injure or kill people after a tsunami inundates a coastline?
What two instruments do scientists use to determine if a tsunami has been generated by an earthquake?
How long does it take to issue a tsunami warning? Why are warnings only effective for locations 750 km or more from the origin of the tsunami?
List the three factors that influence the effectiveness of a tsunami early warning system.
Why were scientists unable to monitor and issue warnings for the 2004 Indian Ocean Tsunami?
