How would you describe a tsunami?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
What are the characteristics of a tsunami wave?
A tsunami in the deep ocean has very long wavelengths and very low amplitude. Approaching the shore the tsunami will slow down in speed and amplitudes will increase dramatically. This is due to the fact that the tsunami’s energy flux, which is dependent on both its wave speed and wave height, remains nearly constant.
What a tsunami wave looks like?
Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide.
How many waves does a tsunami have?
3.1 How many waves are there in a tsunami? A tsunami is a series of waves, not just one. These waves are often referred to as the tsunami wave train.
3. Tsunami Characteristics.
|Wave Speed||500-600 miles per hour (in deep water) 20-30 miles per hour (near shore)||5-60 miles per hour|
What is a typical tsunami wavelength?
A very large wind-generated wave might have a wavelength of 200 meters (650 feet), but a typical tsunami has a wavelength of 200 kilometers (120 miles). … Incredibly, tsunamis can travel at 800 kilometers per hour or kph (500 miles per hour or mph) in the open ocean.
Which of the following best describes tsunamis?
A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. … Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height.
Is it possible to surf a tsunami?
You can’t surf a tsunami because it doesn’t have a face. Many people have the misconception that a tsunami wave will resemble the 25-foot waves at Jaws, Waimea or Maverick’s, but this is incorrect: those waves look nothing like a tsunami. … On a tsunami, there’s no face, so there’s nothing for a surfboard to grip.
