2.  The tsunami is a series of water waves
caused by the displacement of a large
volume of a body of water, typically an ocean
or a large lake . Earthquakes , volcanic
eruptions and other underwater explosions
(including detonations of underwater.)

3.  How are tsunamis generated Tsunamis can be
generated when the sea floor abruptly
deforms and vertically displaces the overlying
water. Tectonic earthquakes are a particular
kind of earthquake that are associated with
the earth's crustal deformation; when these
earthquakes occur beneath the sea, the
water above the deformed area is displaced
from its equilibrium position. Waves are
formed as the displaced water mass, which
acts under the influence of gravity, attempts
to regain its equilibrium. When large areas of
the sea floor elevate or subside, a tsunami
can be created.

4.  On the average, there are two tsunamis per
year somewhere in the world which cause
damage near the source. Approximately
every 15 years a destructive, Pacific-wide
tsunami occurs. The destructive tsunami on
Dec 26th, 2004 on the Indian Coast seems to
have occurred for the first time in the
history.

5.  What to do after a tsunami Continue listening to a
NOAA Weather Radio, Coast Guard emergency frequency
station, or other reliable source for emergency
information. The tsunami may have damaged roads,
bridges, or other places that may be unsafe. Help
injured or trapped persons. Give first aid where
appropriate. Call for help. Do not move seriously
injured persons unless they are in immediate danger of
further injury. Help a neighbour who may require
special assistance--infants, elderly people, and people
with disabilities. Elderly people and people with
disabilities may require additional assistance. People
who care for them or who have large families may need
additional assistance in emergency situations.

6.  Tsunamis in India The first tsunami to struck
India was back in December 31, 1881.
However, the government of India indicated
that around 11,000 people died and more
than 5,000 were missing and were assumed
dead by the Home Affairs Ministry. An
estimation points out that about 380,000
Indians displaced by this tsunami. It is
expected that reconstruction of these
affected places would cost over 1.2 billion
dollars from the World Bank.
