What is the precautionary measures for tsunami?
Signs that s Tsunami is Approaching
There are some signs that could warn you if a tsunami is going
to happen. Take note of the following: 1. If an earthquake occurs
near a body of water.
2. If water along a shoreline recedes dramatically.
3. Some kinds of animals hear the noise of tsunami and move
towards the opposite direction towards inland.
4. When you hear a loud roar similar to that of a train or an
The tsunami warning system consists of sensors
that can detect tsunamis andcommunications system that could alarm
to allow evacuation of coastal areas. Since tsunamismove at 0.14 to
0.28 km/s and earthquake waves at 4 km/s, it is assumed that, when
an earthquake is confirmed, there is enough time to predict a
tsunami.To reduce the effect of a tsunami, a tsunami wall of 4.5
meters in height can be constructed in populated coastal areas.
Floodgates and channels can be built to redirect the water from the
tsunami, and the shore can be covered with trees. All these slow
down and moderate a tsunami. However, they cannot totally prevent
the destruction and loss of life. Before a tsunami Watch out
for warning signs. Remember to run uphill when you are near the
shore and you felt an earthquake, when you observe animals heading
uphill or away from the shore, or when you observe the water at the
beaches recede into the sea. During a Tsunami If you run
uphill on the first warning signs, you will probably have enough
time to reach safe high ground. If not, the only thing you can try
is to climb up a tree, although there is no assurance that the
water will not reach you. The best thing is to run at the first
warning signs or when an evacuation announcement has been made.
After a Tsunami to wait for some time to make sure there are
no other waves coming after the first wave before you clear up the
debris. A tsunami is a series of waves. The first wave may not be
the most dangerous. The waves may come five minutes apart to an
hour apart. The cycle may be marked by repeated retreating and
advancing of the ocean or sea. Do not go to the shore once the
first wave has gone. Expect more to come.
