Japan’s devastating combination of earthquake and tsunami was a wakeup call reminding companies across the world how much they rely on nature to commerce business. On Friday 11 March 2011, an earthquake measuring 9.0 on Richter scale struck off Japan’s north-east coast of Tohoku which happened at 2:46pm (Alabaster et al. 2011). The massive earthquake was caused due to thrust faulting where rocks placed lower in the earth’s crust get pushed over the overlying layers (Alabaster et al. 2011). After the earthquake, the shadow depth underneath the ocean triggered a major tsunami hazard that reached height of up to 40.5 meters, which later on experienced rapidly after the quake.…

Tsunami s are a series of giant sea waves created when a large volume of a body of water, such as an ocean, is rapidly displaced. Earthquakes, volcanic eruptions and other underwater explosions, landslides, asteroid impacts, and other mass movements above or below water all have the potential to generate a tsunami. Due to the immense volumes of water and energy involved, the effects of tsunamis can be devastating. Their hazards can be split into primary and secondary effects. Primary effects are the immediate effects of a hazard impact whereas secondary effects are the after-effects that occur as a result of the hazard and can be present for a long time, as the problems do not stop when the hazard event is over.…
A tsunami is a series of waves created when a body of water, such as an ocean, is rapidly displaced on a massive scale. Earthquakes, mass movements above or below water, volcanic eruptions and other underwater explosions, landslides, large meteorite impacts and testing with nuclear weapons at sea all have the potential to generate a tsunami. The effects of a tsunami can range from unnoticeable to devastating. The term tsunami comes from the Japanese words(津波、つなみ) meaning harbor ("tsu", 津) and wave ("nami", 波). Although in Japanese tsunami is used for both the singular and plural, in English tsunamis is often used as the plural. The term was created by fishermen who returned to port to find the area surrounding their harbor devastated, although they had not been aware of any wave in the open water. Tsunami are common throughout Japanese history; approximately 195 events in Japan have been recorded. The word tsunami is pronounced tsu-nah-mee or tsoo-nah-mee; /tsʊˈnɑːmi/.…
The term tsunami originates from Japanese and means “harbour wave” .It is a series of waves when a body of water, such as an ocean is rapidly displaced on a massive scale. Tsunamis cannot be prevented or precisely predicted, but there are many systems being developed to warn and save the people of regions with a high risk of tsunamis before the wave reaches land.…
It’s almost hard to believe the havoc entailed with a tsunami. The Ocean is so huge that it travels that far and still picking up speed. The after math of one disaster becomes several clenching catastrophes. The variation of a wave train catching people by surprise, a powerful water wall delivers about a hundred thousand tons of water. The creation of a tsunami is wondrous how it grows so quick. But where are the warning signs?…
On the morning of December 26, 2004 a magnitude 9.3 earthquake struck off the Northwest coast of the Indonesian island of Sumatra. The earthquake resulted from complex slip on the fault where the oceanic portion of the Indian Plate slides under Sumatra, part of the Eurasian Plate. The earthquake deformed the ocean floor, pushing the overlying water up into a tsunami wave. The tsunami wave devastated nearby areas where the wave may have been as high as 25 meters (80 feet) tall and killed nearly 300,000 people from nations in the region and tourists from around the world. The tsunami wave itself also traveled the globe, and was measured in the Pacific and many other places by tide gauges. Measurements in California exceeded 40 cm in height, while New Jersey saw water level fluctuations as great as 34 cm .…
Through this course, many topics were analyzed. It was interesting to know that all waves, even from the smallest ripple to the most destructive tsunami, have similar characteristics. For example they all have crests, troughs, wave heights, lengths, and periods. Also, water particles that make up the waves all move in identical orbital patterns and only when waves become unstable this motion is destroyed.…
Natural disaster is a phenomenon that happens naturally, threatening the humans ' lives and damaging the properties. On Friday, 11 March 2011 at 14:46:23 JST, a 9.0 magnitude earthquake happened under the sea of Japan and cause a tsunami with height 133 feet in Tōhoku. It caused thousands of people to die, injured and missing, and damaging…
All tsunamis are caused by the sudden displacement of large volumes of water. All are the result of violent events with enough power to displace large volumes very rapidly. Moreover, Tsunamis are often referred to high waves of water caused by changes in the flow and surge of the ocean. On the other hand, Tsunamis can be caused by a few different factors, which are an earthquake, a large-scale undersea landslide, a submarine volcanic eruption (Cause of Tsunami, n.d.).…
Tsunamis, triggered by an undersea earthquake as well as seiches – waves coming from lakes shaken by a temblor – can submerge whole communities, sweep away edifices, topple trees and drown people.…

Tsunami are notorious natural hazards causing destruction to life, infrastructures, economies and environments. These highly destructive waves have wreaked havoc in the last decade, predominantly in coastal settlements of South-Pacific Asia; as partly demonstrated in Flores, Indonesia in1992 (Tsuji et al., 1995), in Hokkaido, Japan in 1993 (Shuto and Matsutomi, 1995; Shimamoto et al., 1995) and in Papua New Guinea in 1998 (Goldsmith et al., 1999; Kawata et al., 1999). The effects of tsunami in a human context can be attributed to what was previously said where the listed targets of destruction all involve some human aspect. The involvement of a human aspect with tsunami, transforms the giant displacements of water into a natural disaster. In this essay we wish to discuss how tsunami are natural disasters in a human context. This will be achieved by reviewing the human environmental damage caused by tsunami. In particular, two infamous tsunami events of the 21st century will be explored: The Boxing Day tsunami of 2004 and the 2011 Tōhoku tsunami.…
A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.[3]…
