As a cause-driven observance, World Tsunami Awareness Day focuses on education and fundraising rather than commercial deals.

Corporate partners often support these initiatives through matching gift programs or by promoting educational materials. Companies like Google, with its Public Alerts and Crisis Response tools, and IBM, which applies AI for disaster preparedness, may highlight their contributions.

History of World Tsunami Awareness Day
On December 22, 2015, the United Nations, through resolution 70/23, designated November 5 as World Tsunami Awareness Day. Although they are rare, tsunamis are one of the most devastating and dangerous natural disasters. They have no borders since they do not affect only coastal communities. They also reach and destroy other towns and communities that are located away from the coast.
Coastal communities are the most vulnerable when there is a risk of a tsunami. Even though tsunamis are hazardous, there are often natural warnings that a tsunami may be approaching. It could be strong ground shaking, volcanic eruptions, or the water receding unusually far and exposing the seafloor. International cooperation is key in trying to raise global awareness about effective actions, policies, and practices to reduce exposure to this kind of natural disaster.
About 58 tsunamis have taken more than 260,000 lives in the past 100 years, more than any other natural disaster. The highest number of deaths during those 100 years occurred in December 2004 when the Indian Ocean tsunami took place. It caused approximately 227,000 fatalities in 14 countries, including Indonesia, Sri Lanka, India, and Thailand. Just three weeks after that tsunami, the international community came together in Kobe, Japan, where Governments adopted the 10-year Hyogo Framework for Action. This agreement was the first comprehensive global agreement on disaster risk reduction.
Rapid urbanization and growing tourism in tsunami regions are putting even more people in danger. That is why it is so important that the world makes everything possible to achieve a substantial reduction in disaster mortality.
World Tsunami Awareness Day timeline
An earthquake and tsunami kill 118 people along the western coast of Puerto Rico.
It causes 110 deaths, some as far away as Crescent City, Califonia.
It reaches heights of 65 to 100 feet in Sumatra and causes more than 200,000 deaths from Indonesia to East Africa.
The United Nations General Assembly designates this day to promote global culture on tsunamis.
How Businesses Can Celebrate World Tsunami Awareness Day
Local businesses in coastal areas can play a critical role in World Tsunami Awareness Day by reviewing and updating their own emergency plans. They can host public information sessions, distribute educational materials from local emergency services, or participate in community-wide evacuation drills. Restaurants and retailers might offer small discounts to customers who can demonstrate they’ve signed up for local emergency alerts, encouraging preparedness across the community.

Tsunamis are rare but devastating events; over the last 100 years, more than 260,000 people have been killed by tsunamis, making them one of the deadliest natural hazards. Approximately 700 million people live in low-lying coastal areas globally, making them vulnerable.
Which countries are most at risk of tsunamis?

What causes a tsunami?
Tsunamis are most commonly caused by large undersea earthquakes that displace a massive volume of water. Other causes can include volcanic eruptions, underwater landslides, or even meteorite impacts, all capable of generating powerful ocean waves.
