One key difference is that tsunamis move through the entire water column, the full depth of the ocean – from the ocean surface to the ocean floor – while other ocean waves only affect the near-surface layer of the ocean. This is because of how they are generated. Basic anatomy of a wave.
This of course begs the inquiry “How do tsunamis differ from regular waves?”
Normal ocean waves are caused by the wind, weather, tides, and currents, whereas tsunamis are powered by a geological force. Tsunami waves are surface gravity waves that are formed as the displaced water mass moves under the influence of gravity and radiate across the ocean like ripples on a pond.
When we were writing we ran into the query “What is the difference between ocean waves and tsunamis?”.
The most usefull answer is; basic anatomy of a wave.

• A tsunami is not a single wave but a series of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive. Tsunamis are not tidal waves. • Tsunami waves can be very long (as much as 60 miles, or 100 kilometers ) and be as far as one hour apart.
Is a tsunami and a tidal wave the same thing?
These terms, tidal wave and tsunami, refer to the same natural phenomenon; an unusually large ocean wave caused by an earthquake, underwater landslide, or other large disturbance. They are not, however, used interchangeably and tsunami is now the preferred term.
Why is a tsunami referred to as a tidal wave?
Tsunamis are sometimes referred to as tidal waves. This once-popular term derives from the most common appearance of a tsunami, which is that of an extraordinarily high tidal bore. Tsunamis and tides both produce waves of water that move inland, but in the case of a tsunami, the inland movement of water may be much greater, giving the impression of an incredibly high and forceful tide.
What is the difference between a tsunami and a wind swell?
The wind-generated swell one sees at a California beach, for example, spawned by a storm out in the Pacific and rhythmically rolling in, one wave after another, might have a period of about 10 seconds and a wave length of 150 m. A tsunami, on the other hand, can have a wavelength in excess of 100 km and period on the order of one hour.
How do tsunamis move the ocean?
Sound waves, radio waves, even “the wave” in a stadium all have something in common with the waves that move across oceans. It takes an external force to start a wave, like dropping a rock into a pond or waves blowing across the sea. In the case of tsunamis, the forces involved are large — and their effects can be correspondingly massive.
To understand tsunamis, it is helpful to understand how they are different from the familiar ocean waves one might see when standing on a beach. Even though tsunamis and these other ocean waves have the same basic anatomy, they are really quite different. Basic anatomy of a wave.
Most other ocean waves are caused by wind blowing over the water (wind waves). Typical tsunami sources, like earthquakes, can generate more energy than the wind. Key differences between tsunamis and wind-driven waves.
Tsunamis with runups over one meter (3.28 feet) are particularly dangerous to people and property. Yet, smaller tsunamis can also be dangerous. Strong currents can injure and drown swimmers and damage and destroy boats and infrastructure in harbors.
