Aftermath of the December 2004 tsunami in Aceh, Indonesia.
The Japanese word tsunami translates to "harbour wave". It is derived from the Japanese terms tsu, meaning "harbour," and nami, meaning "wave".12
A tsunami is a catastrophic ocean wave typically generated by submarine earthquakes, underwater or coastal landslides, or volcanic eruptions. While these events are sometimes referred to as tidal waves, they are unrelated to the tides.2
