About World Tsunami Awareness Day
World Tsunami Awareness Day falls every year on November 5 and was established by the United Nations to help coastal communities understand tsunami risk before the water ever arrives. A tsunami is a series of powerful ocean waves usually triggered by undersea earthquakes, and it can race across entire oceans in hours and strike shorelines with devastating force. The day exists to close a simple but deadly gap: many residents of coastal areas still do not know the natural warning signs or the correct response.
The campaign is championed by the UN Office for Disaster Risk Reduction and supported by governments, schools, and scientific agencies worldwide. In recent years the focus has widened from fast, earthquake-driven waves to rarer volcano-triggered tsunamis, such as those that followed the 2022 eruption of Hunga Tonga-Hunga Ha'apai, which sent shockwaves across the Pacific. Drills, school lessons, public alert tests, and museum exhibits all play a part.
The date honors Japan's Inamura-no-hi story, in which a village elder burned his own rice sheaves on a hilltop to guide neighbors to high ground before the 1854 Ansei tsunami waves arrived.
History of World Tsunami Awareness Day
The date November 5 recalls the Ansei-Nankai earthquake and tsunami of 1854, when the Japanese legend of Inamura-no-hi, the burning of rice sheaves, saved the villagers of Hiromura. After the 2004 Indian Ocean tsunami killed more than 227,000 people across a dozen countries, the UN established the Indian Ocean Tsunami Warning System, agreed in 2005. Japan repeatedly proposed a global awareness day, and on December 22, 2015, the UN General Assembly designated November 5 as World Tsunami Awareness Day. Resolution 70/203 called on all countries and organizations to observe the day and share tsunami risk knowledge. Since then, annual themes have rotated among preparedness, early warning, and the targets of the Sendai Framework for Disaster Risk Reduction, linking the day to broader resilience goals such as reducing disaster deaths and improving multi-hazard alert coverage.
