When in open ocean a tsunamis are usually only a few feet high and often hundreds of miles long. Even with their high speed they often take several minutes to pass.

When they enter shallow water they slow down and increase in height.

A tsunami is not typically visible in deep ocean waters because it has a long wavelength and low amplitude, causing the wave height to be small compared to the water depth. This makes it difficult to detect visually. It is only when the tsunami approaches shallow waters near coastal areas that the wave height increases, leading to the devastating impact we associate with tsunamis.

What is the medium for a tsunami?

A tsunami is typically generated by the displacement of a large volume of water, usually from undersea earthquakes, volcanic eruptions, or landslides. The medium through which a tsunami travels is water, specifically ocean water.


When a tsunami travels through the ocean does it affect whales?

Tsumanis won't affect whales as they travel through the ocean because it would just be another wave out at sea. If the whales were close to shore they could be swept inland, though.


Does a tsunami travel radially outward from its epicenter?

Yes, a tsunami travels outward from its epicenter in a series of waves in all directions. The energy generated by an undersea earthquake causes the ocean water to displace and form a tsunami that spreads across the ocean.


What is the average speed of the wave?

Tsunamis can travel over 600 mph in the open ocean. It can only take a few hours for a tsunami to travel across an entire ocean. A regular wave travels at 90 km/hr. http://www.enchantedlearning.com/subjects/tsunami/


What speed does a tsunami wave move through the open ocean?

23 mph


How many liters of water does a tsunami contain?

The amount of water in a tsunami can vary greatly depending on the size and strength of the wave, but in general, a tsunami can contain millions of liters of water as it travels across the ocean and crashes onto land.


What is the difference between seismic wave and tsunami?

Seismic waves are vibrations that travel through the Earth's layers during an earthquake, whereas a tsunami is a series of large ocean waves caused by displacement of water, often triggered by an undersea earthquake, volcanic eruption, or landslide. Seismic waves originate within the Earth, while tsunamis occur on the ocean's surface.
