The March 27, 1964 "Good Friday" earthquake rocked Southcentral Alaska with 5 minutes of shaking. The magnitude 9.2 earthquake left communities in ruins and triggered a tsunami that traveled south at over 500 mph towards Oregon. When the tsunami struck Oregon and California hours later, it destroyed homes, flooded communities and killed 11 people. It remains the largest tsunami in U.S history.
