APRIL is Tsunami Awareness Month in Hawai'i!
2023 marks 77 years since the April 1, 1946 Aleutian Islands earthquake that generated a tsunami that hit Hawai'i 4.5 hours later, without warning, killing 158 people statewide, including 120 on the Big Island mostly in and around Hilo. The tsunami led to the establishment of the US Seismic Sea Wave Warning System in 1948 in Honolulu. Today, NOAA's Pacific Tsunami Warning Center provides US tsunami warning center services to the State of Hawaii, as well as American Samoa, Guam and the Commonwealth of the Northern Marianas Islands, Puerto Rico, and the US Virgin Islands.
