World Tsunami Awareness Day

What day is it?

Human casualties caused by tsunamis can be measured in hundreds of thousands of people. Despite the danger of this natural disaster, people are able to minimize the number of victims and damage caused. The cause of tsunamis is underwater earthquakes with high magnitude. Seismological scientists insist on the dissemination of information in order to save human lives. Compared to other natural disasters, tsunamis occur less often and do not last as long, but its destructive power should not be underestimated. The UN General Assembly proposed to hold the Tsunami Awareness Day annually on November 5.

How did the idea of ​​celebrating World Tsunami Awareness Day come about?

At all times, man was drawn to water. We all know the calming power it has. However, in a matter of seconds, water can turn from a place of peace and reliability into a terrible angry element that spares no one.

The “younger” brother of the tsunami can be considered storm waves. The difference between them is that during a tsunami, water affects not only the surface water, but also the water mass in the ocean column.


Tsunamis outpace even the wind and reach up to 700 km/h. In addition to underwater earthquakes, tsunamis can also be caused by landslides of glaciers, volcanic eruptions, and meteorites falling into the ocean. The word “tsunami” itself is formed by two Japanese words – “tsu” (harbor, port) and “nami” (wave).

Over the last century, the number of intervals between tsunamis has decreased, which means that they should be expected to occur more often. The accident at the Fukushima nuclear power plant in 2001 is the result of a tsunami that was caused by an earthquake.

In order for the society to be more aware, the UN decided to determine one day when citizens of the whole world will be introduced to information on how to protect themselves during such a disaster.

The date was chosen in honor of a Japanese peasant. On November 5, 1854, he donated his harvest to save his village and fellow villagers. He was the first to notice the impending disaster and set fire to his sheaves of rice. People saw the fire and managed to leave their houses and village in time. When the tsunami was over, he made every effort to rebuild the village.


That is why, in December 2015, on the initiative of the Japanese delegation, it was established to celebrate November 5 as the Tsunami Awareness Day.
