World Tsunami Awareness Day is observed annually on November 5th to raise awareness about the importance of tsunami preparedness and the need to mitigate the risks associated with tsunamis. The United Nations General Assembly designated this day in 2015, following a proposal made by Japan, which has had a long history of dealing with devastating tsunamis.

The purpose of World Tsunami Awareness Day is to promote a global culture of tsunami awareness, including early warning, preparedness, and mitigation. Efforts are made to educate people about the measures that can be taken to reduce the risks posed by tsunamis, as well as the importance of community-based disaster risk reduction. This day serves as a platform to share knowledge and promote actions that can help protect communities and save lives in the event of a tsunami.

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.

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.


History of World Tsunami Awareness Day

World Tsunami Awareness Day was established by the United Nations General Assembly in December 2015, with the first commemoration held on November 5, 2016. The proposal for this day originated from Japan, a country that has experienced some of the most devastating tsunamis in history, including the Great East Japan Earthquake and Tsunami in 2011.

The 2011 disaster was a significant impetus for the international community to recognize the importance of preparedness and mitigation efforts for tsunamis. The devastating impact of the tsunami on Japan’s eastern coast, including the Fukushima Daiichi nuclear disaster, underscored the critical need for global awareness and collaboration to minimize the risk and impact of such events in the future.

World Tsunami Awareness Day serves as a platform to promote education, preparedness, and awareness about the risks associated with tsunamis. Its main goal is to reduce the loss of life and property damage caused by these destructive natural phenomena. The day is marked by various events, activities, and educational programs aimed at educating people about the importance of early warning systems, evacuation procedures, and community-based disaster preparedness.


Through initiatives like World Tsunami Awareness Day, the international community seeks to strengthen cooperation and coordination in disaster risk reduction, enhance early warning systems, and promote resilience in vulnerable coastal communities around the world. It serves as a global reminder of the ongoing need for vigilance and preparedness in the face of natural disasters, particularly those as potentially devastating as tsunamis.

Significance of World Tsunami Awareness Day

World Tsunami Awareness Day holds significant importance due to several key reasons:

  • Risk Reduction: The day serves as a reminder of the potential threat posed by tsunamis, prompting communities and authorities to take necessary measures to reduce the risks associated with these natural disasters.
  • Education and Preparedness: World Tsunami Awareness Day emphasizes the importance of education and preparedness in coastal communities. It encourages the dissemination of knowledge about early warning systems, evacuation procedures, and other essential measures to minimize the impact of tsunamis.
  • Global Collaboration: The day fosters international cooperation and collaboration in the field of disaster risk reduction. It encourages countries to share their experiences, best practices, and technological advancements related to tsunami preparedness and response.
  • Community Resilience: By highlighting the importance of community-based resilience, the day encourages local communities to take an active role in developing and implementing strategies that can help mitigate the impact of tsunamis and enhance their ability to respond effectively during emergencies.
  • Policy Advocacy: World Tsunami Awareness Day serves as a platform for advocating policy initiatives and investments in early warning systems, disaster preparedness, and infrastructure development, with the aim of reducing the vulnerability of coastal areas to tsunamis.
  • Memorialization of Past Events: The day also serves as a memorial for the victims of past tsunami disasters, honoring their memory by raising awareness and promoting actions that can help prevent similar tragedies in the future.

By highlighting the significance of World Tsunami Awareness Day, communities and policymakers can work together to minimize the risks associated with tsunamis and build more resilient societies that are better equipped to handle such natural disasters.
