What is a Tsunami? A Tsunami is a set of huge waves of water
that are usually caused by earthquakes or volcanic eruptions. This
happens when an underwater earthquake pushes the water upwards and
creates a series of long waves that travel at approximately eight
hundred kilometers per hour towards the seashore. The Tsunami waves
get higher as they reach the shallow water. At that point, the
water on the shore might retreated into the ocean and the big
Tsunami waves will then strike the coast and damage everything in
front of them up to one kilometer inland.

What is a Tsunami (continued)? A Tsunami is not only a series
of huge waves crushing everything that is in front of them, but
they even make really dangerous floods, and in the end of the
Tsunami coastal flood, all the water is retreated back into the
ocean. These huge waves are one of the most deadly natural
disasters by the way that they smash or kill every single thing
standing in their way. Tsunamis can also be formed by volcano
eruptions, land slides and earthquakes.
Slide 5
Where do Tsunamis occur most? Most Tsunamis occur in the
pacific and Indian oceans. Tsunamis mostly occur near countries
like Japan, India and Indonesia. Regions in Tsunami danger zones
often have warning systems in place to give as much time as
possible to run away. Japan has the most probability than any other
place in the world for a Tsunami to happen. In fact Japan has had
most Tsunamis than any other place in history.

The 2004 Indonesian Tsunami - disaster. In December 2004, a
powerful earthquake moved the seabed off Indonesia in Southeast
Asia. Strong waves spread out like ripples. The waves travelled
3,100 miles to wreck towns on the shores of India and even Africa.
The damage caused by the Tsunami was worst on the coast of
Indonesia. Whole towns were completely flattened by waves. Boats
were swept onto the shore and carried far inland. This Tsunami was
given four names: 2004 Indian Ocean Tsunami, South Asian Tsunami,
Indonesian Tsunami or Boxing Day Tsunami.
Slide 7
How does global warming link to Tsunamis? Scientists say that
as the atmosphere heats up and geology is altered, global warming
may trigger even more Tsunamis or other natural disasters.
Disappearing Greenland and Antarctic Ice sheets threaten to let
loose underwater landslides, triggering Tsunamis that could reach
the coast of Britain. It seems that changes in the earths crust may
cause more Tsunamis, but Tsunamis have no direct link with global
warming.
