NOVA: Wave That Shook the World
1: What is a tsunami?
A long high sea wave caused by an earthquake, submarine landslide, or other disturbance.2: When did this tsunami happen?
It occurred in 2004
3: How many people died, in how many countries?
227,898 people died in 15 countries
4: What is the name of the warning center in Hawaii?
Pacific Tsunami Warning Center
5: An area where one tectonic plate is pushing under another is called?
It's called a subduction zone
6: What magnitude was this earthquake? What is a seismograph? It measured an 8.6 magnitude earthquake. A seismograph is an instrument that measures and records details of earthquakes, such as force and duration.
Each unit in magnitude is a factor of _______ of radiant energy of an earthquake.
Earthquake scientists get paged when an earthquake of a factor of ______ or larger
occurs.
7: How do tsunami sensor buoys work? Explain.
How many warning sensors/buoys are there in the Pacific? There are 39 sensors in the Pacific and
In the Indian Ocean?
8: This earthquake was shallow. How many kilometers deep was it?
9: What is “tsunami initiation”? Explain.
11: How fast does the tsunami wave travel? Why is this different than a “surfer’s wave”?
12: What does a boat in the open ocean feel during a tsunami wave?
13: What warning sign often occurs at the beach during a tsunami? What is
Amplification?
If the waves on the beach suddenly suck out and expose the ocean floor for a large
distance out, WHY should you not run out to check it out? What should you do
instead?
14: Is there usually only one wave in a tsunami?
Is there a pattern to the waves? Explain.
15: Where is greater damage likely, on a gently sloping beach or a steeply sloping beach?
Explain why.
16: True or false, you are safe as the tsunami wave is passing back out?
17: How did the quake affect the earth’s day?
18: What area of the United States is at risk for the same type of earthquake?
19: What are the four causes of a tsunami?
How many people on Earth are at risk of a tsunami?
20: What is happening in the Cascadia Subduction Zone? What could happen?
21: What is being done to help prepare for future tsunamis?
22: How many more buoys did the United States add to the Pacific Warning system?
What else is part of the Tsunami warning system?
Assignment: Using the information given in this video, create a newspaper article that
describes the tsunami event on December 26, 2004. (make sure to include who, what,
where, why, when, how).
Article at least 1 page in length and must include a diagram and a photo.
