Hilo, Hawaii

On April 1, 1946 a 7.8 magnitude earthquake near the Aleutian Islands created a 14-meter high tsunami that hit Hilo hours later killing 159. As a result an early warning system was established to track these killer waves and provide warning. On May 23, 1960, another tsunami, caused by an 8.6 magnitude earthquake off the coast of Chile the previous day, claimed 61 lives due to failure to heed warning sirens. Low-lying bayfront areas of the city, previously populated, were rededicated as parks and memorials.
