1. Tsunami in Japan 2011
Japan was hit by an enormous earthquake on March 11, 2011, that triggered a deadly 23–foot
tsunami in the country's north. The giant waves deluged cities and rural areas alike, sweeping
away cars, homes, buildings, a train, and boats, leaving a path of death and devastation in its wake.
Video footage showed cars racing away from surging waves. The United States Geological Survey
reported the earthquake and on Monday revised its magnitude from 8.9 to 9.0, which is the largest in
Japan's history. The earthquake struck about 230 miles northeast of Tokyo. The PacificTsunami
Warning Center issued warnings for Russia, Taiwan, Hawaii, Indonesia, the Marshall Islands, Papua
New Guinea, Australia, and the west coasts the U.S., Mexico, Central...show more content...

2. Essay on The Tsunami Disaster
The Tsunami Disaster At 0059 GMT on 26 December 2004, a magnitude 9.3 earthquake ripped apart
the seafloor off the coast of northwest Sumatra.
Over 100 years of accumulated stress was released in the second biggest earthquake in recorded
history.
It unleashed a devastating tsunami that travelled thousands of kilometres across the Indian Ocean,
taking the lives of nearly 300,000 people in countries as far apart as Indonesia, the Maldives, Sri
Lanka and Somalia.
THE EARTHQUAKE
Two hundred and forty kilometres (150 miles) off the coast of Sumatra, deep under the ocean floor,
at the boundary between two of the world's tectonic plates, lay a 1,200km (745...show more content...
"We were astonished to find ourselves walking through a pristine marine ecosystem, missing only its
multitude of colours, its fish, and its water," said Professor Kerry Sieh, from the California Institute
of Technology, US.
Yet, when the shaking from the earthquake subsided, no–one had any idea that the tremors had set in
motion something far more deadly – a tsunami.
THE TSUNAMI
Deep under the Indian Ocean, at the epicentre of the quake, the 20m (65ft) upward thrust of the
seafloor set in motion a series of geological events that were to devastate the lives of millions.
Billions of tonnes of seawater, forced upward by the movement of the seabed now flowed away from
the fault in a series of giant waves.
The only people in the world to have any idea what had happened were thousands of kilometres
away on the island of Hawaii.
But, relying on seismic data alone, the scientists at the Pacific Tsunami Warning Centre had no idea
the earthquake had unleashed an ocean–wide tsunami.
It was a full 50 minutes after they first picked up the tremors that they issued a warning of a possible
local tsunami.
Thirty minutes after the shaking had subsided, the first wave, travelling eastwards, crashed into
Sumatra.

3. On the shores directly facing the epicentre, the waves reached heights of 20m (65ft), stripping
vegetation from mountain sides 800m (0.5 mile) inland,

4. Essay On Tsunamis
Since Tsunamis have occurred, there has been a considerable amount of destruction to buildings
and structures. People have spend Millions in rebuilding these structures which is not benefiting
the economy and this disaster has been continuously been in the news and also has been
happening around the world especially in the Ring of Fire. This part of the world is disastrous as
many seismic sea waves, earthquakes and volcanoes occur. [1] There are many problems relating
to waves that affect people over the world. Some waves being very dangerous while other not as
much. Tsunamis (Seismic sea Waves) is a series of very huge waves which are created by
underwater disturbances including earthquake, landslide, volcanic eruptions or meteorites. [2]
Tsunamis are one of the most deadliest and destructive disasters as...show more content...
One major limitation to Curved seawalls or seawalls in general is that they ruin the view and
scene for tourists. Although, seawalls protect and prevent any harm to human residence, a big tall
concrete structure instead of an open area with a view will ruin the tourist attraction in an area.
Coming to a beach, people and especially tourists would expect to have a beautiful scene with
nothing blocking their sight. Would a concrete wall ruin tourists view on shorelines or beaches?
This connects to a social aspect as people want to enjoy and have fun at the beach with sunny
weather and also a great view, but with a big concrete wall, tourists and people would not feel that
welcomed. This also connects to Beach reviews online as tourists might comment something
negative about the scene and view. This also connects to an economical aspect because tourists will
not be as attracted to the beach or shoreline as they used to be, meaning, that the workers in stores,
shops or workers doing activities will not earn as much money as not many people would be there.

5. Tsunami Essay
Tsunamis become disasters because of the human context in which they occur. Do you agree or
disagree with this statement? Use examples of known tsunami events recently and in the past to
illustrate your arguments.
According to Wisner et al 2004, "disasters occur when hazards meet vulnerability," implying that in
unpopulated areas hazards can not become disasters as there is no vulnerability (Quarantelli E.L.
1998). Without humans being involved, tsunamis are nothing but giant waves; they may modify
areas of uninhabited land and destroy some reefs but that does not make them disasters. Tsunamis
become disasters when humans are involved; when their lives are at risk, their homes are destroyed,
their livelihoods are lost etc. In addition,...show more content...
The landscape was altered unrecognisably, with large areas of coastlines washed away and some
landmarks shifted to new locations. Debris and waste were widely scattered and farmland and
underground water supplies flooded (Global Education, 2009). According to Grossman (2012), the
large amount of the estimated 25 million tons of debris caused by both the Tohoku earthquake and
tsunami washed away into the sea could hit the Hawaiian Islands and have catastrophic
consequences, such as damage to the reefs and beaches that are homes of many indigenous species.
The Tohoku tsunami resulted in the Fukushima nuclear power plant accident with three reactors
melting down: the largest nuclear accident since the 1986 Chernobyl disaster (Kyutoku et al., 2012).
Officials from the Japanese Nuclear and Industrial Safety Agency reported that radiation levels
inside and outside the plant were up to 1,000 times and 8 times normal levels respectively
(Tabuchi and Walk, 2011). The reactors of the nuclear plant sustained major damage to the cooling
system meaning that radioactive isotopes were released into the air, ultimately leading to
contamination of soil, water and food. Radioactive chemicals were found in tap water in many
cities, as well as in the soil and food products (Hur, 2011). Damage and destruction of water
treatment and sewage systems increase the likelihood of outbreaks of cholera and typhoid, although
outbreaks are less likely to

Introduction:
A massive Tsunami (Japanese for "Harbor wave") had hit southern Asia the day after Christmas
2004. The cause of the Tsunami was an offshore earthquake that results in the tectonic plates being
displaced and the creation of a vertical shift in the ocean floor. This vertical shift lead to a large
volume of water being uplifted and turned to create a huge wave that traveled up to 300 miles per
hour, gradually slowing as it reached the shore. At that time, people in...show more content...
These countries had neither the proper disaster warning systems nor any type of acceptable
emergency shelters. Additionally, they did not have an ample number of hospitals, medicines,
supplies of food and enough shelters to care for the survivors of the tsunami. Therefore the
wounded died suffering infections, hunger and depression and left thousands possibly missing. The
tsunami washed parts of countries away leaving the inhabitants in total devastation. Though, the
worst is yet to come. It has been found that people are now drinking from tainted water supplies,
since the fact that many resources or cargoes were unable to reach the people in a timely manner.
The need for clean water is pressing. Health officials say that cases of diarrhea illness were reported
across the areas of South Asia. The World Health Organization predicated that about five million
survivors of the calamity are at the risk of getting infections from the disease (Dr Samlee
Plianbangchang, 2005). Volunteers attempting to treat the survivors are still struggling to provide
the necessary help across all the nations affected. In addition to the diarrhea illnesses, there are major
concerns about other illnesses such as cholera and typhoid. People can become infected very easily
with the consumption of tainted food and water. Once infected, the individual can suffer form
diarrhea, dehydration, and eventually death. Other illnesses

Environmental Science
Tsunamis
A tsunami (soo–NAH–mee) is a series of waves that occur in an ocean or other large body of water
and that are caused by some activity that displaces big amounts of water. Tsunami is the Japanese
word for "harbor wave."
Earthquakes that occur on the seafloor or in coastal areas usually cause tsunamis.
The energy generated by the earthquake is transmitted through the water. In deep oceans the energy
in these seismic sea waves can travel virtually unnoticed because the wave height may be only
twelve inches. When this energy reaches the shallow waters of coastlines, bays, or harbors, it forces
the water into a giant wave. Some...show more content...
Fishermen twenty miles out to sea didn't notice the wave pass under their boats because it only had a
height at the time of about fifteen inches. They were totally unprepared for the devastation that
awaited them when they returned to the port of
Sanriku. Twenty–eight thousand people were killed and 170 miles of coastline were destroyed by
the wave that had passed under them.
Tsunamis in deep water can have a wavelength greater than 300 miles (500
2)
kilometers) and a period of about an hour. This is very different from the normal
California tube, which generally has a wavelength of about 300 feet (100 meters) and a time of
about ten seconds. (The period of a wave is the time between two successive waves.) Tsunamis are
shallow–water waves, which means that the ratio between water depth and wavelength is very small.
These shallow–water waves move at a speed equal to the square root of the product of the
acceleration of gravity (9.8m/s/s) and the water depth.
The deeper the water, the faster and shorter the wave is. For example, when the ocean is
20,000 feet deep, a tsunami travels at 550 miles per hour. At this speed, the wave can compete with a
jet airplane, traveling across the ocean in less than a day.
Another important factor in considering tsunamis is the rate at which they lose energy. Because a
wave loses energy at a rate inversely related to its
