About Tsunami

A tsunami is a set of gigantic waves often caused by volcanic eruptions or earthquakes happening near or below the ocean. It is among the most destructive natural calamities.

In the past 100 years, 58 significant tsunamis have occurred worldwide, causing over 260,000 lives. On average, every tsunami caused 4,600 lives, exceeding any other natural uncertainty.

Over the past twenty years, tsunamis have estimated almost 10 percent of global economic losses from disasters.

Currently, above 700 million humans exist in low-lying coastal regions and tiny islands. As per the US, it is expected that about 50% of the earth’s population will live in coastal areas by 2030. They may be presented to severe sea-level events, including tsunamis and flooding.


At first, World Cities Day was formally taken on 5 November 2016.

On 22nd December 2015, the UN General Assembly chose the fifth of November as World Tsunami Day, by its decision A/RES/70/203, asking nations and world groups to promote tsunami awareness and share innovative efforts.

The UN General Assembly chose the date of 5th November to celebrate the Japanese legend of “Inamura-no-Hi” (indicating “burning of the rice sheaves”).


During an earthquake in 1858, a Japan-based farmer noticed the tide falling and understood a tsunami was nearly to hit. He set fire to alert other villagers so they could escape to high areas. Later, the farmer made a dam and planted trees to preserve the village from future hazards.

How to observe the Day

Since 2016, many nations and cities have hosted various events to spread awareness for tsunamis, including lectures, conferences, educational programs, seminars, and social media campaigns.

Every year a particular theme is chosen, by the United Nations, to raise tsunami awareness and share innovative efforts.
