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

airplane.

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.
