| environ. | sea wave A moving ridge or swell of water occurring close to the surface of the sea, characterized by oscillating and rising and falling movements, often as a result of the frictional drag of the wind | val marin |
| environ. | seismic sea wave A large seismically generated sea wave which is capable of considerable destruction in certain coastal areas, especially where submarine earthquakes occur.

The wavelength in the open ocean is of the order of 100 to 150 km and the rate of travel of a seismic sea wave is between 640 and 960 km/h | undă seismică marină |
