A tsunami is a series of water waves caused by the displacement of a large volume of water, often from earthquakes, volcanic eruptions, landslides or other disturbances below or above water. Tsunami waves have a very long wavelength and can cause enormous destruction in coastal areas, with wave heights over tens of metres. The 2004 Indian Ocean tsunami was one of the deadliest natural disasters, killing over 290,000 people across 14 countries.

TSunami - A natural Disaster which is like a Giant devil galloping the whole world. A Tsunami is a series of ocean waves that are usually caused by seismic events.
The word Tsunami is a Japenese word and is pronounced as ‘soo-nah-mee.’
It means ‘harbour wave’ with ‘tsu’ meaning harbour and ‘nami’ meaning wave A Tsunami is a series of ocean waves that are usually caused by seismic events.
Tsunami is a Japanese word Tsu means ‘harbour’ and nami means ‘wave’.
They are called tidal waves but they have actually nothing to do with the tides. However their appearance from shore is similar to rapidly rising or falling tides.
Tsunami is a series of wave created when water is moved very quickly.
Tsunami is gravity wave system, triggered by vertical disturbances in ocean. They are long waves sometime with hundreds of miles b/w their crests, just like the concentric waves generated by an object dropped into a pool.
First tsunami was recorded in 1480 B.C. in eastern Mediterranean, when the Minoan civilization was wiped out.
A large tsunami accompanied by the earthquake of Lisbon in 1755.
The Kutch earthquake of June 16, 1819 generated strong tsunami which submerged the coastal areas and damage to ships and country made boats of fishermen.
North and South American records have dated such
events back to 1788 for Alaska and 1562 for Chile. Records of Hawaiian tsunami go back to 1821.
Tsunami hits the Mona Passage off Puerto Rico in 1918, grand banks of Canada in 1929.
This is a PowerPoint Presentation based strictly on Tsunami.

A series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water by a large event.
7. A tsunami (plural: tsunamis or tsunami; from Japanese: 津波, lit. "harbour
wave";[1] English pronunciation: /suːˈnɑːmi/ soo-NAH-mee or /tsuːˈnɑːmi/ tsoo-
NAH-mee[2]) 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]
Tsunami waves do not resemble normal sea waves, because their wavelength is
far longer. Rather than appearing as a breaking wave, a tsunami may instead
initially resemble a rapidly rising tide, and for this reason they are often
referred to astidal waves. Tsunamis generally consist of a series of waves
with periods ranging from minutes to hours, arriving in a so-called "wave
train".[4] Wave heights of tens of metres can be generated by large events.
Although the impact of tsunamis is limited to coastal areas, their destructive
power can be enormous and they can affect entire ocean basins; the 2004 Indian
Ocean tsunami was among the deadliest natural disasters in human history
with at least 290,000 people killed or missing in 14 countries bordering
the Indian Ocean.
14. TSUNAMI IN ANDAMAN & NICOBAR
A severe earthquake measuring 8.9 Richter scale, was felt in Andaman and Nicobar
Islands having epicentre at 3.7N and 95E off the island of Sumatra between 0630 to 0635
hours in the morning of 26th December, 2004. The quake was followed the "Killer
Waves" or Tsunami which caused extensive damages to life & property in this
archipelago.
But we would like to draw the attention of all about the true picture of the effect/damage.
The maximum damage has been in the Nicobar group of Islands and NOT in the
Andaman group of islands. If you look at the map of the Andaman & Nicobar Islands ,
you will find that Andaman & Nicobar are two completely different group of islands.
The entire Andaman group of islands (excepting Little Andamans) have been literally
spared from the devastating Tsunami. Most importantly there has been no injuries or
deaths amongst tourists - since tourists are anyway not allowed to visit the Nicobar group
of islands.
Things are now fast coming back to normal here. Since, there has been no big damage in
any of the major/popular tourist spots/destinations (like Port Blair, Havelock, Neil island,
etc.) - Indian Airlines & Jet Airways have restarted their daily scheduled flights from
Kolkata (Calcutta) & Chennai (Madras) and tourists are now allowed to come here once
again.
There was a temporary prohibition (just as a precautionary measure) on scuba diving for
sometime - which has also now been removed. So, tourists can now once again go for
diving, snorkeling, game fishing, etc.
16. TSUNAMI IN
PORT BLAIR (THAI LAND)
Tsunamis are large waves of water usually triggered by an earthquake,
explosion or other event displacing a large amount of water. Out in the open
ocean, tsunamis are typically harmless and unnoticeable to the naked eye.
When they start, tsunami waves are small and wide -- the height of the waves
can be as small as a foot, and they can be hundreds of miles long and move
very quickly, so they can pass practically unnoticed until the get to shallow
water closer to land. But as the distance between the bottom of the ocean floor
and the water gets smaller, these short, wide, fast waves compress into
extremely high, powerful waves that wash onto land. Depending on the
amount of energy involved, they can reach more than 100 feet in height.

The 2004 Tsunami, referred to as the 2004 Indian Ocean Tsunami, the 2004
Indonesian Tsunami or the 2004 Boxing Day Tsunami, was one of the worst
natural disasters in recorded history. It was triggered by an undersea
earthquake with an estimated magnitude of between 9.1 to 9.3, making it the
third most powerful quake ever recorded.
The tsunami that the massive earthquake generated killed more than 230,000
people in Indonesia, Sri Lanka, India and Thailand, displaced hundreds of
thousands of people and caused billions of dollars in property damage.
22. Tilly Smith (born 1994) is a British woman who, as a girl aged 10,
was credited with saving nearly a hundred foreign tourists at
Maikhao Beach in Thailand by warning beachgoers minutes before
the arrival of the tsunami caused by the 2004 Indian Ocean
earthquake.
Tilly Smith learned about tsunamis in a geography lesson two
weeks before the tsunami from her teacher Andrew Kearney
at Danes Hill School in Oxshott, Surrey. She recognised the
symptoms of receding water from the shoreline and frothing
bubbles on the surface of the sea and alerted her parents, who
warned others on the beach and the staff at the hotel
on Phuket where they were staying. The beach was evacuated
before the tsunami reached shore, and was one of the few beaches
on the island with no reported casualties.
At Danes Hill Preparatory School a cameraman was allowed to
follow Smith around for a day to find out what she normally did at
30. TSUNAMI IN GALLE
The country of Sri Lanka (formerly Ceylon), located 31 miles off the south-eastern coast of
India, was hit by a tsunami triggered by a 9.0 magnitude earthquake off the coast of Sumatra
on December 26, 2004. The tsunami was one of the worst disasters ever recorded in Sri
Lankan history. The tsunami left tens of thousands dead, many more homeless, and caused
widespread chaos throughout the island. In addition to the human impacts, the tsunami had
widespread effects on Sri Lanka's environment and ecosystems. It is still too early to express
the long-term effects caused by the tsunami, but short-term effects are clearly evident.
Human Impacts
Civilian casualties in Sri Lanka were second only to those in Indonesia (see Indonesia).
Reports vary on the number of deaths since many people are still missing and the country
lacks adequate communications. As of March 1, 2005, estimates state that 36,603 people
perished in the months following the tsunami. Another 800,000 people living on the coasts
of Sri Lanka have been directly affected. The eastern shores of Sri Lanka faced the hardest
impact since they were facing the epicenter of the earthquake. The southwestern shores were
hit later, but the death toll was just as severe.
The coastal lifestyle of people in Sri Lanka contributed to the high death tolls. The following
images illustrate the correlation between population, affected areas, and mortality rates. In
addition to the high number of fatalities, approximately 90,000 buildings were destroyed.
Houses were easily destroyed since they were built mostly from wood. This wooden debris
that was left behind is now raising issues of its own

34. The term tsunami has its origins in the Japanese language; an English equivalent is "seismic sea
waves." Tsunamis are often incorrectly interchanged with the term" tidal waves," which refer to
high waves of water caused by changes in the flow and surge of the ocean. Tsunamis, on the other
hand, can be caused by a few different means: 1) the down drop or upthurst of the Earth’s crust
which results in an earthquake; 2) a large-scale undersea landslide; 3) a submarine volcanic
eruption of a certain degree; or potentially, 4) a large meteor impact at sea. The vast majority of
tsunamis result from earthquakes.

How Earthquakes Cause Tsunamis
The illustration below shows a subduction earthquake (one where a denser plates shifts below its
neighboring plate, at left). Energy is transferred and the displaced water forms a wave. As the
wave travels and enters shallower water in the coastal area, it begins to increase in amplitude
(National Geographic).
Killer Wave! Tsuanmi--National Geographic Kids
Tsunamis are not always colossal waves when they come into the shore. In fact, "... most
tsunamis do not result in giant breaking waves (like normal surf waves at the beach that curl over
as they approach shore). Rather, they come in much like very strong and very fast tides (i.e., a
rapid, local rise in sea level)." (USGS website) Nevertheless, there is destruction of life and of
property by floating debris and impact of water. The tsunami produces a series of rushing waves
and also a series of withdrawals.
