Difference between Tsunamis and Ocean Waves
The word tsunami (pronounced soo-NAH-mee) is Japanese; it is derived from tsu, which means harbor, and nami, which means wave. A tsunami is a series of huge waves. It washes against the coast several times with great speed and force.
How are Tsunamis caused?
Sometimes an underwater earthquake causes a huge displacement of water which can generate a tsunami. These giant waves travel thousands of miles across the sea. Not only earthquakes but also landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis.
Difference between Tsunamis and ocean waves
Tsunamis occur as a result of the movement of a huge volume of seawater from the seabed to the sea surface, whereas ocean waves are caused by the movement of wind over the sea surface. Tide embankments can protect us from ocean waves, but are sometimes overwhelmed by tsunamis.
