1.Introduction:
A tsunami warning system (TWS) is used to detect
tsunamis in advance and issue warnings to prevent loss of life and
damage. It is made up of two equally important components: a network
of sensors to detect tsunamis and a communications infrastructure to
issue timely alarms to permit evacuation of the coastal areas.
2. What is Tsunami:
A tsunami is a series of waves caused by
earthquakes or undersea volcanic eruptions. ... Out in the depths of
the ocean, tsunami waves do not dramatically increase in height.
But as the waves travel inland, they build up to higher and higher
heights as the depth of the ocean decreases.
3. How Tsunami Occurs:

A large wave on the ocean, usually caused by an
undersea earthquake, a volcanic eruption, or coastal landslide. A
tsunami can travel hundreds of miles over the open sea and cause
extensive damage when it encounters land. Also called tidal waves.
4.Earth Quake:
The shaking or trembling caused by the sudden release of
energy. Usually associated with faulting or breaking of rocks.
Continuing adjustment of position results in aftershocks. 80%
of all earthquakesoccur in the circum-Pacific belt most of these

result from convergent margin activity.15% occur in the
Mediterranean-Asiatic belt remaining 5% occur in the interiors
of plates and on spreading ridge centers more than 150,000
quakes strong enough to be felt are recorded each year.
Can Earthquakes be Controlled?
• Graph showing the relationship between the amount of
waste injected into wells per month and the average
number of Denver earthquakes per month.
• Some have suggested that pumping fluids into seismic
gaps will cause small earthquakes while preventing large
ones

5. Richter Magnitude Scale :
Measures the Magnitude of an earthquake on a ten
(10) point scale. In 1935, Charles Richter introduced the
concept of earthquake magnitude. Richter magnitude is
determined by measuring the largest amplitude (wave height)
recorded on the seismogram.

Richter magnitude can be expressed in two ways:
1. Wave amplitude increases ten fold (10X).
2. Energy released increases thirty fold (30X).
1. Wave amplitude increases ten fold(10X):
Wave amplitude increases tenfold (10X) with each
increase in Richter magnitude. Each increase in 1 in Richter
Magnitude represents a 10 fold increase in the wave
amplitude (height). Thus, a magnitude 7 earthquake
measures 10 times more amplitude than a magnitude 6

earthquake. A magnitude 8 earthquake measures 10 x 10
(or 100 times) more amplitude than a magnitude 6
earthquake. And so on.
2. Energy released increases thirty fold (30X):
Energy released increases thirtyfold (30X) with each
increase in Richter magnitude. Each increase in 1 in
Richter Magnitude represents a 30 fold increase in the
energy released (size). Thus, a magnitude 7 earthquake
releases 30 times more energy than a magnitude 6
earthquake. A magnitude 8 earthquake releases 30 x 30
or 900 times more energy than a magnitude 6 earthquake.
And so on ….

6. Volcanic Eruption:
7. Tsunami warning system:
A Tsunami Warning System (TWS) is a system to detect
tsunamis and issue warnings to prevent loss of life and
property. In 1949 PTWC was invented by the following the
1946 aleutin island earthquake and a tsunami that resulted in
165 casulaties on Hawaii and Alaska . NTWC was founded in
1967.

8. Seismometers:
When a tsunami event occurs, the first information available
about the source of the tsunami is based only on the available seismic
information. Earthquakes are measured based on its magnitude
recorded by a seismograph.
The seismometer together with the unit recording the signal is
called a seismograph. The seismometer senses the ground vibration
and converts this to a signal that can be recorded. Seismographs can

detect, amplify, and record ground vibrations too small to be
perceived by human beings. Modern seismographs can measure
movements smaller than one nm.
9. DART System:
The DART tsunami detection buoy is deployed in the ocean
from a ship. When an earthquake generates a tsunami , the
magnitude of the resulting tsunami wave is measured by the
tsunameter , and transmitted via satellite to the tsunami warning
centers. Whereit is used to improve the accuracyof the tsunami
forecast.

10. Conclusion:
The Tsunami warning system is very
important system. If there was no tsunami warning system ,
more people might die by tsunami .The issue of the tsunami
warning system is very serious problem. People should solve
this problem. In 2004 many people was dead by tsunami
because the tsunami warning system was not perfect. That
experience is based on , current system is improved , and
protect many lives of people from tsunami.
