![]() The highest tidal waves are found in the Bay of Fundy, in the Canadian province of New Brunswick, where the water level can rise with the tide by 50 feet. ![]() Although, the impact of a tsunami could be influenced by the tidal level at the time it strikes. So, as tsunamis are not related to tides, it is incorrect to consider them a type of tidal waves. While a tsunami differs from 5 minutes to an hour, the wavelengths of a tidal wave differ from 12 to 24 hours. There is also difference in wavelengths between a tsunami and a tidal wave. Because of the diverse causes, a tsunami has the potential to develop anywhere, unlike a tidal wave. The water above such an event is disturbed in such a way that it creates a surface wave with a speed of hundreds of miles per hour (typically around 500 mph on average). The most common reason for a tsunami is an undersea earthquake. The ocean floor may be displaced by an earthquake landslides moving into oceans, bays, or lakes volcanic eruptions a crashing asteroid or underwater explosions, so the water column is uplifted. It is a series of waves caused by a rapid, massive displacement of the seafloor or disruption of standing water. As a rule, tidal waves follow the currents and are unlikely to cause a landfall in areas of temperate climates or northern countries.Ī tsunami, on the other hand, is an extraordinary event. It is also possible that a tidal wave will burn out before it reaches the coast. Due to this fact, water levels may raise by several feet in a matter of hours. ![]() Tidal waves are most pronounced in narrow bays or in rivers along the coast. ![]() It is a result of the daily tides caused by the imbalanced, gravitational influences of the Moon, Sun, and planets (hence the name). However, there is a significant difference between tsunamis and tidal waves based on their origins and characteristics.Ī tidal wave is quite a predictable event impacted by the atmosphere. It is true that both of these types of waves may be very destructive. 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. Myth: Any big surge of water from the oceans is called a tidal wave the terms “Tsunami” and “Tidal Waves” mean the same and are interchangeable. ![]()
