World Tsunami Awareness Day is observed annually on November 5 to raise awareness about the dangers of tsunamis and the importance of early warning systems and community preparedness.

World Tsunami Awareness Day is celebrated on November 5 each year. Its primary goal is to make people aware of how to reduce the risks associated with tsunamis and improve community readiness. In 2023, the theme of this day will be aligned with the International Day of Disaster Reduction, focusing on combating inequality for a more resilient future.

During this time, various activities will delve into the connection between tsunamis and inequality. These will highlight how inequality can make tsunamis more devastating for specific groups and how the aftermath of a tsunami can push vulnerable individuals further into poverty, worsening inequality.

The United Nations reports that in the last century, there were 58 tsunamis that claimed over 260,000 lives, averaging about 4,600 deaths per event, making tsunamis the deadliest among all natural disasters. The most catastrophic tsunami during this time occurred in the Indian Ocean in December 2004.

What Is A Tsunami?

A tsunami is a term for massive waves that form due to disturbances beneath the ocean, often triggered by undersea earthquakes. Tsunamis are a kind of natural disaster and can be extremely destructive to people and their belongings. The word ‘tsunami’ originates from Japanese, where “tsu” means harbour and “nami” means wave.

What Causes Tsunamis?

Tsunamis typically happen when there are earthquakes under or near the ocean. They result in a series of massive waves. Tsunamis can also occur due to volcanic eruptions, underwater landslides, rocks falling into the ocean, or even if a big asteroid hits the water.

Tsunami Awareness Day: Significance

Over the past century, as many as 58 tsunamis have brought about widespread destruction, claiming the lives of over 260,000 individuals. This natural disaster has caused more casualties than any such event in history. Hence, observing World Tsunami Awareness Day is crucial.
