“Tsunami” is a Japanese word. Tsu means “harbor” and nami means “wave.”
On the open spaces of the ocean, a fast-moving tsunami may only be a few feet high, with 100 miles separating wave crests. As they approach shore, waves increase in height and currents intensify, which create a bigger threat to life and property.
Few tsunamis “break” like the waves seen in wind-generated waves popular with surfers. Tsunamis are more often associated with strong currents and walls of water that do not retreat like normal tidal waves do.
Tsunamis may be local, regional, or far away. The type of tsunami depends on the location of where the tsunami started and where it may hit land.
