NOAA Wave That shook the world
1. What is a tsunami?
A giant wave with great amounts of energy.
2.When did this tsunami happen?
December 26, 2004
3.How many people died in how many countries?
260,000 people died in 4 different countries.
4. What is the name of the warning center in Hawaii?
The Pacific tsunami warning center.
5.An area where one tectonic plate is pushing under another called?
Subduction
6.What magnitude was this earthquake? What is a seismograph?
Each unit in magnitude is a factor of 30 of radiant energy of an earthquake. the magnitude was a 9.
7. How do tsunami buoys work?
They are detectors in the water and travel with the waves. If the buoy has gone high in the air they know a tsunami is coming.
8. This earthquake was shallow How many kilometers deep was the earthquake?
This earth quake was only 30 Km deep
9. What is "Tsunami initiation?"
Tsunami initiation is When the earthquake raises the water and then splits.
1o.How fast do tsunamis travel?
500 Mph or 1000 Km.
A giant wave with great amounts of energy.

Tsunami initiation is When the earthquake raises the water and then splits.
1o.How fast do tsunamis travel?
500 Mph or 1000 Km.
12. What is "Tsunami Initiation"? Explain.
When water rises and begins to split in different directions. Or when a sudden offset changes the elevation of the ocean and initiates a water wave that travels outward from the region of sea-floor disruption.
13. How fast does the Tsunami wave travel? Why is this different than a surfers wave?
It can go up to 500 to 1,000 km/h (310 to 620 mph)
14. What does a boat in the open ocean feel during a Tsunami wave?
The boat will barley notice the wave under them.
15. What warning sign often occurs at the beach during a Tsunami? What is Amplification?
When the water goes further into the ocean instead of the beach and severe ground shaking.As a tsunami approaches shorelines, water may recede from the coast, exposing the ocean floor, reefs and fish.Abnormal ocean activity, a wall of water, and an approaching tsunami create a loud "roaring" sound similar to that of a train or jet aircraft.
16. Is there usually only one wave in a Tsunami? Is there a pattern to the waves? Explain.
No! There usually is more waves coming but it could be at any moment, hour, day, week. Yes, the pattern is that some are larger than others.
17. Where is greater damage likely, on a gentle sloping beach or a steeply sloping beach? Explain why.
Gentle slope because the wave can go through it easily.
18. True/False, you are safe as the Tsunami wave is passing back out.
FALSE
19. How did the quake affect the earths day?
It made the weather change and made it darker.
20. What area of the United States is at risk for the same type of earthquake?
The West Coast is more likely at risk since it's the closest to the ocean.
21. What are the four cause of Tsunami? How many people on the earth are at risk of a Tsunami?
Asteroids, earthquakes, volcanoes, and landslides. Millions.
22. What is happening in the Casadia Subduction Zone? What could happen.
Land is going under ground. An Earthquake/Tsunami could happen.
23. What is being done to help prepare for future Tsunami's?
More pressure sensors and monitors being put around most near the countries more at risk.
24. How many more buoys did the United States add to the Pacific Warning System?
39 more buoys.
