Travelling at nearly 500 miles per hour, a succession of tsunami waves hit the Hawaiian Islands around breakfast time, devastating downtown Hilo on Hawaii Island and killing 96 people. Across the Hawaiian island chain, 159 people lost their lives to the tsunami.

Another contributing factor was uninformed city planning that allowed residents to rebuild homes and businesses in tsunami risk zones. Shinmachi, a district in downtown Hilo rebuilt after the 1946 tsunami, was destroyed again by the 1960 tsunami. While sobering, these tragedies are critical teaching opportunities.
