In Japanese, a tsunami means a huge wave. In fact, the name fully corresponds to reality, but every year such waves cause enormous damage to many coastal cities and countries. Scientists say that there are many reasons for its formation, but the main one is an underwater earthquake. To avoid tragedy, you should remember some safety tips for tsunamis.
Shifts form because of the tremors at the bottom of the ocean – one part of the bottom goes down, the other starts to rise. All of this causes a sudden movement of water reaching the surface. But as soon as this mass tries to return to its original state, huge waves will begin to form.
Earthquakes in the ocean may or may not be felt on land. If an earthquake is strong enough, the first damage will come from it. Even at this point, people in the coastal area need to think about safety precautions for tsunamis and possible flooding.
If the tremors are observed in the open ocean, the height of the waves may not exceed one meter. According to experts, such oceanic earthquakes pose no danger to navigation because the width between the wave crests is too wide.
After the sudden cessation of the tremors, there is a lull. It seems that the danger has passed, but the wave keeps moving. The waves move in circles from the epicenter of the earthquake, as if a stone had been thrown at the epicenter. The body of water moves inexorably toward the shore, and sooner or later, there comes a moment when the lower part of the wave touches the bottom. The lower part slows down not evenly but practically stops. At this point, it is too late to run because there are only a few minutes left before the disaster, although it is as dangerous to stay in the house as it is outside.
At the back, the wave is still moving due to the impossibility of getting anywhere. It simply overlaps upwards the whole length. Logically, the speed of the wave will fall, and the height will rise, which is why the deadly waves reach forty meters or more. The thickness of the water collapses onto the shore, simply because it has nowhere else to go, and this is called a tsunami.
The sudden danger is almost impossible to predict, although seismological stations monitor it. After each major earthquake, the tsunami immediately begins to move toward the shore.
To save yourself from it in advance, you have to be careful. The ocean literally moves away from the shore while the wave is still coming. So coastal residents need to keep their eyes on the ocean at all times. Not for meditation, but for safety.
But we are all living people – we want to eat to sleep, read blogs, and not watch the movements of the water at all. And if we talk about locals, they must buy the necessary medicines, warm clothes, special goggles, and a respirator in advance.
As for tourists, they should remember that the best protection from a tsunami is a timely evacuation. It is useful to study the plan in advance so it will be much better to navigate in an extreme situation. Usually, all emergency information is transmitted by radio or television.
In the event of a natural disaster, the main thing to do is not to panic – you need to get to shelter as soon as possible. Staying in the house is dangerous because the big wave can knock out all the windows. The risk of getting hurt by shards or fragments of furniture increases at times. It is strictly forbidden to use vehicles because visibility is reduced, and any movement on the road is dangerous. The force of the wave will simply wash the car off the road or, worse, carry it back into the ocean.
