What is a tsunami wave geology quizlet?
Tsunami. a wave train or series of waves generated in a body of water by an impulsive disturbance that vertically displaces the water column or by the transfer of momentum to the ocean water.
What is the definition of tsunami wavelength quizlet?
-Tsunami wave has wavelength of 100-200km with deep water heigh of 1m or less. -Travels as fast as 200 m/s (440mi/hour) in open ocean. -As it approaches the shore, it slows, steepens, and rises. What does it mean “The wave keeps coming”?
What is a tsunami quizlet oceanography?
A tsunami is a series of water waves (“splash waves”). They can happen in lakes, frequently in Japan, many different causes. Tsunami. A series of waves with very long wavelengths (100-200 km) and periods (10-80 minutes). Their periods are much longer than storm-generated swell.
Why is a tsunami called a tsunami?
The word tsunami (pronounced tsoo-nah’-mee) is composed of the Japanese words “tsu” (which means harbor) and “nami” (which means “wave”). … Thus, the Japanese word “tsunami”, meaning “harbor wave” is the correct, official and all-inclusive term.
What forces generate tsunamis quizlet?
Most tsunamis are caused by earthquakes generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces. The friction between the subducting plate and the overriding plate is enormous.
Which type of seismic wave has the fastest velocity?
P-Waves. The P in P-waves stands for primary, because these are the fastest seismic waves and are the first to be detected once an earthquake has occurred. P-waves travel through the earth’s interior many times faster than the speed of a jet airplane, taking only a few minutes to travel across the earth.
What did the government of Japan do after the Fukushima disaster quizlet?

What is a characteristic of a tsunami quizlet?
Tsunamis have a very long wavelength (sometimes over 100km) and a low wave height (under 1 metre) in the open ocean, and they travel quickly at speeds of over 700km per hour but, when reaching shallow water bordering land, increase rapidly in height.
What happens to a tsunami wave as it approaches the shore quizlet?
What happens to a wave when it reaches the shore? As the wave comes near the shore, the ocean floor starts to slope upward towards the beach (the slope is called the continental shelf). The ocean floor causes friction on the wave and the wave length gets shorter and the wave hight increases.
