Hazards are anything that could cause damage to humans or buildings. Many volcanic and seismic events happen that cause hazards to humans. Often the world’s poorest people are hit the worst‚ however wealthier countries can also be adversely affected. The Kobe earthquake in Japan 1995 struck at 5.45am. Many people were asleep in bed‚ causing the hazard to be increased because the people were unaware. Although many Japanese buildings were of aseismic design‚ the roofs of their houses were designed

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

motions in the seafloor can sometimes generate enormous waves‚ called tsunamis that can devastate entire coastlines. Also‚ regular patterns of smooth‚ rounded waves in the open ocean are called swells. Swells are defined as mature undulations of water in the open ocean after wave energy has left the wave generating region. Like other waves‚ swells can range in size from small ripples to large‚ flat-crested waves. In conclusion‚ ocean waves have a significant impact on the shape of the Earth’s coastlines

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

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
