In 2011, a major earthquake and tsunami destroyed much of the capital infrastructure in Japan. Those natural disasters were examples of a: negative shock to the LRAS curve. positive shock to the LRAS curve. negative shock to the AD curve. positive shock to the AD curve.

A tsunami is a massive sea wave caused by earthquakes, volcanic eruptions, underwater landslides, and meteor impacts. Natural warning signs are often monitored and observed to prevent this sea wave. One of the signs is a felt shaking of the ground. If you are in a tsunami-prone area while the ground is shaking, protect yourself first by doing the Drop, Cover, and Hold On. Immediately go to higher ground when the shaking stops. Another sign is sea recession which is the receding of the water exposing the normally submerged areas. If this is observed, immediately run away from the shore. And the last sign to look for is hearing an unusual noise similar to that of a train or jet aircraft. Do not wait for an official warning if one of the natural signs of an impending tsunami is observed.

I. Read the paragraphs below and make sure to comprehend. In your answer sheet, answer the guide questions that follow. A. Tsunamis can be generated when the sea floor abruptly deforms and vertically displaces the overlying water. Tectonic earthquakes are a particular kind of earthquake that are associated with the earth's crustal deformation; when these earthquakes occur beneath the sea, the water above the deformed area is displaced from its equilibrium position. Waves are formed as the displaced water mass, which acts under the influence of gravity, attempts to regain its equilibrium. When large areas of the sea floor elevate or subside, a tsunami can be created. Large vertical movements of the earth's crust can occur at plate boundaries. Plates interact along these boundaries called faults. Around the margins of the Pacific Ocean, for example, denser oceanic plates slip under continental plates in a process known as subduction. Subduction earthquakes are particularly effective in generating tsunamis. Guide Questions: 1. How does an earthquake generate tsunami? 2. What specific kind of wave results to a tsunami? 3. What is a tsunami?

A tidal wave or tsunami is usually the result of an earthquake in the Pacific Rim, often 1000 or more miles from Hawaii. Tsunamis are rare but dangerous. Many tsunamis are small and do little damage. However, a tsunami nine meters or higher is very dangerous. Civil Defense authorities sound an alarm telling people near the beach to go to higher ground. About 30% of all recorded tsunamis have been nine meters or higher.†You are writing a report about five recent earthquakes in the Pacific Rim and you want to include a brief statistical profile of some possible events regarding tsunamis in Hawaii. Let r be the number of tsunamis nine meters or higher resulting from five randomly chosen earthquakes in the Pacific Rim. What is the probability none of the tsunamis are nine meters or higher? (Round your answer to three decimal places.)
