2. Question of the Day 1) Please take out a sheet of paper and write your name near the top on the right hand side. 2) Write your answer to the following questions: Last Friday, many people in Japan received a text message warning them of the earthquake 8 seconds before the shaking began. This warning system cost $30 million. Do you think the warning system was “worth it?” Why or why not? Should the U.S. have a similar system?

4. Now Your Turn Interview the partner next to you (can take notes) Interview the partner next to you (can take notes) You will tell me about your partner: You will tell me about your partner: –Name –Brief background –One time they did their best –One thing they don’t like

5. Tsunami Pictures and Videos Answer the following in your notebook or on your piece of paper. 1. What caused the Tsunami? 2. How fast was the Tsunami (in relative terms)? 3. What happens before the Tsunami hits? 4. Does is appear to be several waves or one single large wave? 5. If a similar earthquake occurred off the coast of Washington what do you think would happen here? 6. Are there hazards here like the nuclear reactor plants that we would need to be concerned about?

6. Seismic Waves Homework: Research the facts of the Japan Tsunami 1. What are the size of the waves? How many? 2. What was the size and location of the earthquake? 3. What effects did the earthquake and Tsunami have? Research the risk of a Tsunami in our area: 1. Where would it come from? 2. How big of an earthquake and how close would it need to be? 3. Could the sound be effected? 4. What are the early warning systems we have in place? 5. How could we be more prepared?

8. Entry Task Tsunamis are one of nature’s most powerful forces but one of the least understood. Write a paragraph to convince your congress person that more money should be spent on research on Tsunamis using facts that you have learned so far about possible tsunamis in the Northwest.

12. Seismic Sea Waves Often called Tidal Waves they have nothing to do with tides but are generated by Seismic Activity (undersea volcano, earthquake or landslide) The number of oceanic trenches and volcanoes along the Pacific Basin cause more incidence of seismic sea waves. Think about this: What happens when you lift the edge of a small swimming pool?

13. Seismic Waves Facts 1. Seismic sea waves travel to speeds of 300-500 miles per hour 2. Seismic waves are not visible in the open sea because their height is only a few feet 3. Speed decreases as the wave comes into shore 4. Their huge height allows them to come ashore for a prolonged period of time 5. They come in group of waves-the first is not the longest 6. Wave heights can vary from a few feet to 100 feet 7. There may be a sudden withdrawal of water before the wave http://www.masternewmedia.org/news/2006/12/08/tsunami_video_ke y_video.htm http://www.masternewmedia.org/news/2006/12/08/tsunami_video_ke y_video.htm http://www.youtube.com/watch?v=Iw3Dj6uGT04&NR=1

15. Tsunami Detectors Deep-ocean tsunami detectors, as depicted in this illustration, are being designed by the U.S. to take the surprise out of tsunami attacks. The detectors depend on sensors stationed on the seafloor. When one of the instruments senses a tsunami wave overhead, it will send acoustic signals to a buoy at the surface, which will relay the warning via satellite to officials who will sound an alarm.

17. Homework: Write a paper on what you would do if you were in charge of preparing residents for an impending Tsunami. Use the following questions to think about what you would do: What would you think were the important pieces to consider to inform residents? What would you spend local tax dollars on?
