6.05 Tsunamis | Purpose: To investigate tsunamis Introduction:I have always been fascinated by tsunamis. I have to say that when I vacationed in Hawaii and snorkeled in the Pacific Ocean‚ I did give a fleeting thought to tsunamis. In the last activity‚ I mentioned that the characteristics and behaviors of waves that you learned from the video could be applied to other waves. As you complete this activity‚ I want you to think about the similarities between the rogue tsunamis and the common waves

velocity as they enter the shore. The top of the wave is called a crest and the bottom is called a trough. The wave crest which will break as it enters the shore. You will view that in this week’s animation. Surface waves should not be confused with Tsunamis or tidal waves. Those are caused by the energy of Earthquakes or other natural disasters. They are massive amounts of water moving out in every direction. Watch the animation‚ Ocean Circulation‚ located in your Week Four area of your Materials

it will take the global population to reach a certain level. Tsunami A tsunami is a high-speed sea wave of seismic origin created by "an underwater earthquake‚ landslide‚ or volcanic eruption"(Johnston‚ 2001). A shallow water wave is a water wave in which the wavelength is larger than the water height‚ or ocean depth (Banks‚ 1998). Since humans are concerned with a tsunami primarily at the shore‚ where the water is not deep‚ tsunami are explored as a shallow water wave. That is‚ people are most

come help in the response effort. This is demonstrated in various situations. The first being the geological hazard of a tsunami. A tsunami is a giant sea wave caused by a large scale and sudden disturbance of sea water caused by large rapid movement of the sea floor initiated‚ nine times out of ten‚ by an earthquake – 90% of tsunamis occur in the Pacific basin. Detection of tsunami relies heavily on earthquake (seismic) monitoring out in the ocean. Taking the Japan Earthquake of 2011 for example‚ the

An earth quake can be described as a shaking of the Earth’s crust. It is mainly a movement of the whole crust that originates in the center of the earth. Earthquakes happen when the underlying rock suddenly shakes or breaks off. The moving of the underlying rock causes the surface rocks to slide and‚ as a result‚ leads to the earthquakes. Earthquakes can be extremely disastrous and cause a lot of damage in the place where they happen. The earthquake can happen once or happen as a series. This depends
