What precautionary measures before during and after tsunami?
Signs that s Tsunami is ApproachingThere 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.
