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 we have studied.Materials:none Procedure: 1. Answer the question based on your exploration on the tsunami website. 2. Submit the assignment according to the directions below.…

Known as one of the worst disasters in the world's history, the Boxing day tsunami took place on December 26, 2004. The tsunami destroyed over 12 different countries and islands, including Sumatra, Indonesia, Malaysia, Thailand, and many more located by the Indian ocean. It had continued trekking countries in the Indian Ocean for over two days and left a devastating mess(Malcolm Moore and Meabh Ritchie). The only good that might have come from this terrible day in history was more knowledge about this disaster and better preparation for more to come.…
The effects of tsunami include damage of properties, the death of humans, serious flooding and diseases.…
A Tsunami forms when energy from an earthquake vertically jolts the seabed by several metres, displacing hundreds of cubic kilometres of water. Large waves begin moving through the ocean, away from the earthquakes epicentre. In deep water the Tsunami moves at great speeds. When it reaches shallow water near coastal areas, the Tsunami slows but increases in height.…
What are tsunamis, and how can we decrease deaths among the human population? Tsunamis are created when underwater tectonic plates rub up against each other creating potential energy and then when they shift, the potential energy turns into kinetic energy which create a very fast wave. Geoscience helps us to better understand them through many ways. Once a tsunami starts, they won’t stop because of all the energy but there are ways to warn people about them through the uses of geoscience. First, geoscientists can predict when and where a tsunami will be formed based on things like earthquake information, detection buoys, tide gauges, etc. these specific tools allow geoscientists to know when to warn the public to evacuate because of tsunamis.…
This is caused by shallow-focus underwater earthquake; volcanic eruption and large land slide into the sea. The displacement of the water becomes the giant sea wave and they normally have a long wavelength over 100m and low wave height when they are still in the open ocean. When it approaches shallower water near the shoreline the speed and the height increases and it can reach 700km/h. tsunami is one of the most deadly seismic hazards can cause significant damage to buildings and infrastructure. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. It killed over 15000 people and the total cost of the disaster was over $300billion and Japan is still recovering today.…
The Earth is 71% oceans. There can be no surprise then that the oceans affects human existence every day. Oceans are a source of economy, leisure, and sustenance. They are also a powerful force to be respected and studied. When the oceans unleash their power and volume in the form of tsunamis the effects are almost always devastating for mankind. These events have changed the course of life on earth more than once. Tsunamis can be triggered by bolide impacts and earthquakes as well as underwater rockslides. Tsunamis have caused mass extinction events, led to significant numbers of human casualties, and produced crippling economic damage. In my lifetime I have witnessed, from afar, the effects of two different tsunamis.…
Lahars travel in the valley bottoms much like pyroclastic flows and kill by suffocation or flooding. Tsunamis can be extremely dangerous also. Tsunamis are giant waves generated either by an earthquake or entire flank of a volcano crashing into to the water. Many tsunamis occur without notice and many die from flooding on the coastline. Non-explosive eruptions can also present dangers.…
On the afternoon of 22 May 1960 the Valdivia Earthquake struck the country of Chile with devastating repercussions for the Chilean people and people around the world. The Earthquake rated a 9.5 on the moment magnitude scale and is, to date, the most powerful earthquake ever recorded. It occurred at roughly 1911 GMT, 1411 local time, and generated a massive tsunami that struck Hawaii approximately fifteen hours later. The tsunami caused little damage to the Hawaiian Islands in general, except in the case of one particular town on the coast of Hilo Bay, on the main island of Hawaii. The tsunami’s power at Hilo Bay was magnified many times compared to its effects throughout the rest of Hawaii. This magnification effect was due to the unique location and topographical features of the bay, which caused the tsunami surges to increase in size and strength by an order of magnitude. In addition to the increase in tsunami size and power, insufficient public education and awareness also contributed to the scope of the disaster. In the end the waves caused nearly $75 million in damage and claimed 61 lives.…
Even though tsunamis and tornadoes are both destructive, on the other hand the destructive power may differ. When tsunamis hit, there is a big initial…

Tsunamis are barely felt as a ripple on the ocean’s surface, but as the waves reach land, they increase in size as the water becomes shallower.…
The 2004 Indian Ocean earthquake was an undersea mega thrust earthquake that occurred at 00:58:53 UTC on Sunday, December 26, 2004, with an epicentre off the west coast of Sumatra, Indonesia. The quake itself is known by the scientific community as the Sumatra-Andaman earthquake.[3][4] The resulting tsunami is given various names, including the 2004 Indian Ocean tsunami, Asian Tsunami, Indonesian Tsunami.…
It was very upsetting to me that these terrible events happened after such a joyous holiday. It was interesting to me how even the buildings were so easily torn down. I also found it interesting how far the water went back after the tsunami hit. Third, I was interested by the fact that the tsunami hit again just moments after the first giant wave. I was comforted by the love and care that the Thai natives showed to Maria when they brought her, Lucas, and Daniel back to their village.…
