World Tsunami Awareness Day
November 5

Recognizing that tsunamis are a global threat, the United Nations General Assembly designated November 5 as World Tsunami Awareness Day. This date was chosen to honor the brave actions of a Japanese farmer and village chief credited with saving many lives from a tsunami on December 24, 1854 (November 5th Japanese calendar).

As many tsunamis do, the event began with an earthquake. After the destructive earthquake, a tsunami wave struck the village of Hiro-mura. Hamaguchi Goryo, a farmer who lived in the village, Hamaguchi Goryo knew a tsunami was a series of waves, not a single wave. Thus, he set fire to his precious sheaves of rice on higher ground, knowing villagers would rush to the site to put out the fire. From the hill top, the villagers saw the next tsunami waves further destroy their village. The villagers understood that it was Hamaguchi Goryo’s actions to attract them to higher ground that saved them from the subsequently larger tsunami waves. See: UN's World Tsunami Awareness Day

NCEI and the co-located World Data Service for Geophysics compile a unique set of tsunami-related products as part of a continuing program to support the interests of tsunami warning centers, engineers, oceanographers, seismologists, and the general public.
