Origins of World Tsunami Day

In the winter of 1854, a magnitude 8.4 earthquake struck Japan’s Kii Peninsula. After the earthquake, Goryo Hamaguchi, an elder in the village of Hiro, set fire to sheaves of newly harvested rice to get the attention of villagers near the coast and guide them to high ground in the darkness. The 1854 tsunami caused damage and casualties, but his actions saved many in Hiro. It became part of Japanese folklore and was recounted by Lafcadio Hearn in 1897 in one of the earliest stories about Japan in the English language.


A Japanese delegation to the United Nations requested that November 5th be designated World Tsunami Day in remembrance of Goryo Hamaguchi and how knowing that tsunamis can quickly follow large earthquakes saved his village. In establishing World Tsunami Day, Yuki Matsuoka, head of the UN Office for Disaster Risk Reduction, explained “Rather than selecting a memorial day or a tragic day, such as 11 March or 26 December, 5 November was selected as a ‘forward-looking’ day when many lives were saved due to proactive actions.” You can learn more about World Tsunami Day by visiting the United Nations website

Learning From Past Tsunamis

Tsunamis can impact people near and far from where they are created.  Learning how tsunamis form, the signs that a tsunami is coming, and how to be safe during a tsunami will save our lives and those around us. Ordinary people can be tsunami heroes and heroines.
