NOVA : The Wave That Shook the World1.What is a Tsunami?
A Tsunami is a big wave created usually by earthquakes but it can be also be created by asteroids , Volcanos , Landslides , and every other geological event.
2. When did this Tsunami happen? (DATE)
December 26, 2004
3. How many people died, in how many countries?
250,000 people died in 12 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?
Subduction.
6. What magnitude was this earthquake? What is a seismograph?
Each unit in magnitude is a factor of 30 or radiant energy of an earthquake.
Earthquake scientists get paged when an earthquake of a factor of 9 or larger occurs.
7.- How do Tsunami sensors buoys work? Explain.
A tsunami buoy is a specialized buoy which is able to detect subtle changes in water pressure which could indicate an incoming tsunami.When a tsunami buoy detects a pressure pattern which could be a tsunami, it immediately sends information to the satellite, and the information is passed on to regional tsunami warning centers.
8.-How many warning sensors/buoy's are there in the pacific?
There are 6 sensor /buoys.
9.-The earthquake was shallow. How many kilometers deep was it?
30 kilometers deep.
10.- What is "Tsunami Initiation"? Explain.
When plates makes the water go up and cause tsunamis.
11.- How fast does the Tsunami wave travel? Why is this different than a surfers wave?
500m/h this is more faster than the normal ones , these waves are different than the surfers wave because their volume is about 30,000 m/h .
12.- What does a boat in the open ocean feel during a Tsunami wave?
The boat doesn't really feel any difference , it just get some turbolences.
13. What warning sign often occurs at the beach during a Tsunami? What is Amplification?
Some of the warming sings in a beach is that the water goes to the center this means the water basically dissapear or goes down and all the animals inside for example fish they go to the surface .Amplification is when the water slows down to the land.
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 out? What should you do instead?
I should not go and check out , because all of these signs are signs of a Tsunami. Instead i should run away from there or scape and teel everybody that go away from there because everybody is at risk staying there.
14. Is there usually only one wave in a Tsunami? Is there a pattern to the waves? Explain.
No , there is usually more than 1 wave in every Tsunami. These may occurs quickly after the 1st one or after a couple of minutes , hours , weeks , etc. Every minute is a risk of having a new Tsunami wave.
15. Where is greater damage likely, on a gentle sloping beach or a steeply sloping beach? Explain why.
There is more damage in a gently slopping beach , because there is no sand walls , or something that can help a little bit the water to goes all the way forward.
16.- True/False, you are safe as the Tsunami wave is passing back out.
False
17. How did the earthquake affect the earths day?
It makes the day shorter , by spinning faster it makes the day shorter.
18. What area of the United States is at risk for the same type of earthquake?
Hawaii and the Pacific North West.
19. What are the four cause of Tsunami? How many people on the earth are at risk of a Tsunami?
Asteroids, earthquakes, volcanoes, and landslides. 1/4 of the world population.
20. What is happening in the Casadia Subduction Zone? What could happen.
Higher risks of Tsunamis.
21. What is being done to help prepare for future Tsunami's?
The Wave Maker.
22. How many more buoys did the United States add to the Pacific Warning System?
39 buoys to increase the protection.
