Differbetween
A tidal wave is by definition a wave caused by ocean tides, whereas a tsunami is almost always caused by an earthquake under water. Tsunami waves are also very different from normal wind-generated waves, which many of us may have observed on a local lake or at a coastal beach.

Is there a difference between a tsunami and a tidal wave?
Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth ("tidal wave" was used in earlier times to describe what we now call a tsunami.)
Why is a tsunami not a tidal wave?
Tsunamis are mistakenly called tidal waves because, when approaching land, they look as a tide which suddenly rushes away and crashes back in a form of a huge wave. ... Tidal waves are most pronounced in narrow bays or in rivers along the coast. Due to this fact, water levels may raise by several feet in a matter of hours.
Can a tidal wave kill you?
A tsunami can kill or injure people and damage or destroy buildings and infrastructure as waves come in and go out. A tsunami is a series of enormous ocean waves caused by earthquakes, underwater landslides, volcanic eruptions, or asteroids. Tsunamis can: Travel 20-30 miles per hour with waves 10-100 feet high.
Are tidal waves dangerous?
Tsunamis can cause great loss of life and property damage in coastal areas. Very large tsunamis can cause damage to coastal regions thousands of miles away from the earthquake that caused them. Beaches, lagoons, bays, estuaries, tidal flats and river mouths are the most dangerous places to be.
What is the world's worst tsunami?
At 7:59 AM, a 9.1-magnitude earthquake—one of the largest ever recorded—ripped through an undersea fault in the Indian Ocean, propelling a massive column of water toward unsuspecting shores. The Boxing Day tsunami would be the deadliest in recorded history, taking a staggering 230,000 lives in a matter of hours.
What is the biggest tidal wave ever recorded?
An earthquake followed by a landslide in 1958 in Alaska's Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.
