One of the biggest natural disasters that can occur is a tsunami that is also often referred to as a tsunami . A large wave caused by the rapid movement of a large volume of water (ocean or sea). We now offer you all the details about the tsunami: what it is, how it forms and where it occurs.
Tsunami: what it is, how it forms and where it occurs
The tsunami is a violent movement of waves from the sea , which can cause waves up to 40 meters high and directed towards the mainland . It is a terrifying phenomenon, which in some cases causes great damage, destroying entire villages along the coast.
A tidal wave can be caused by various phenomena , but in most cases it originates with a violent underwater earthquake . The movements of the seabed give rise to enormous water displacements, which naturally go towards the coast of the nearest continent, reaching the mainland with really huge waves.
In some cases the tidal wave can have heights reaching 40 meters: this means that the destructive power of a phenomenon like this is very high. The water, if it is thrown with force against buildings and people, does not leave an exit and devastates everything in its path to the ground.
However, underwater earthquakes are not always the cause of tsunamis, since tsunamis can also be caused by underwater eruptions or landslides, but these are less frequent events.
Can you foresee the arrival of a tsunami?
Unfortunately, as with the earthquakes that are the main cause, tsunamis cannot be predicted, or rather it cannot be predicted when they will arrive . Today, in the most vulnerable areas such as Hawaii and Japan, measurement tools are used to alert in the event of tsunamis or underwater earthquakes, but this is not enough.
If the earthquake occurs near the continental coast , the tsunami takes a very short time to reach the mainland and there is no way to run for shelter. Therefore, the tsunami can be predicted in a sense, but with too short a time frame compared to the moment of the destructive impact.
How to protect yourself from the risk of a tsunami or tsunami?
The only way to fully protect yourself from the destructive danger of a tsunami would be to avoid building buildings and houses along the coast, at least in the areas of greatest risk. In many cases, this does not happen: we just have to think of Hawaii, which is one of the most popular tourist destinations of all time. However, as we have seen for earthquakes, prevention on our part is the only way to avoid casualties after atmospheric events of this magnitude, against which we are still almost completely defenseless.
