In Japanese, tsunami means "harbor wave." Tsunamis are ocean waves triggered by an earthquake, volcano, or other movement of the ocean floor. Potentially imperceptible in deep water, a tsunami increases in height as it encounters the shallow waters of shore, often leading to extensive wreckage and loss.
