The record shows that damaging tsunamis from distant earthquakes reached Hawaii these years: 1837, 1841, 1868, 1869, 1877, 1883, 1906, 1918, 1923, 1933, 1946, 1957, and 1960. Other smaller tsunamis that caused no significant damage in Hawaii were generated by distant earthquakes in 1896, 1901, 1906, 1919, 1922, 1923, two in 1927, 1928, 1929, 1931, 1938, 1944, 1952, and 1964. In a period of 157 years, a damaging or destructive tsunami struck the Hawaiian Islands on the average of once in every twelve years.
