World Tsunami Awareness Day is celebrated every 5th of November in order to emphasize the importance of disaster prevention and awareness. This day aims to give importance to early warnings, the role of public education on science in order to give a clear understanding of tsunamis, and the development of measures that will mitigate the costly effects of tsunamis.
About World Tsunami Awareness Day
What are the characteristics of a tsunami?
A tsunami is a series of waves brought by sudden disturbances in the sea or ocean. They are most commonly caused by earthquakes under the ocean. But they can also be caused by volcanic activities, landslides, some weather disturbances, and the fall of meteorites into the sea.
Most tsunamis are less than 10 feet in height. But there are extreme cases when they reach over 100 feet. These kinds of tsunamis are those that devastate coastal areas and reach even the mainland cities causing mass flooding, destruction of properties, and death of people. The first wave of a tsunami may only be mild or not damaging. However, the danger of tsunamis can last up to a few hours or even days. Small tsunamis may not devastate coastal areas but they are dangerous to swimmers, surfers, and boats on the ocean.
Any kind of coast is prone to tsunamis. But those that are most vulnerable are low-lying areas like bays, beaches, lagoons, river mouths, and harbors. Tsunamis are very much unpredictable in the long run. They can occur any time, season, or in any weather. They can arise far away from the ocean or even near coasts, the latter of which can arrive in coastal areas only minutes after the disturbance.
How is a tsunami predicted?
Fortunately, experts are now capable of warning people about tsunamis. For instance, the occurrence of earthquakes in the ocean, especially strong ones, can be detected by experts and they can estimate if there will be a tsunami and how high it will be. Doing so will allow them to warn people to evacuate immediately so that they can escape from the havoc of a tsunami.
What is the World Tsunami Awareness Day?
In addition, to help people prevent themselves from getting devastated by a tsunami, World Tsunami Awareness Day was stated. This day aims to inform people about the threat of tsunamis, how to prepare for them, how to restore areas devastated by a tsunami, and how to help people who became victims of a tsunami.
Even though tsunamis are rare, when they occur, they can be extremely devastating and deadly. In the past century, an estimated 300,000 people have died because of tsunamis. The estimated average number of casualties for a tsunami is 4,600, more than any other natural or man-made disaster.
Because of the devastating effects of Tsunami, World Tsunami Awareness Day was declared by the UN General Assembly on the 5th of November. Such date was chosen to commemorate a story in Japan called “Inamura-no-hi”, which means the “burning of the rice sheaves”. This tells a story of the aftermath of an 1854 earthquake wherein a farmer saw the tides receding which is a sign of an upcoming tsunami. To warn the villagers, he set fire to the rice he harvested and made them run to the high ground. Because of that, many lives were saved. After the tsunami, he helped his community withstand the future threats of a tsunami by constructing an embankment along the coast and planting trees that can weaken the force of an upcoming tsunami.
Similarly, World Tsunami Awareness Day wants to do what the heroic man did – to spread awareness about the dangers of a tsunami and the importance of early warning systems that can detect tsunamis and construct measures that mitigate their effects. This special day, in general, also calls on all countries, civil societies, and international bodies to help educate people about tsunamis.
World Tsunami Awareness Day is always celebrated on the 5th of November each year. This means that the upcoming World Awareness Day will be celebrated on, November 5
