Tsunami's and all waves for that matter can move faster than 500mph( 500mph being the average) in open oceanslow when closing in to the shore because of the shallower volume. With tsunami's reaching the coastline the energy concentrates to a smaller energy slows BUT the volume of water is smaller thus a type of containment happens; speed decreases but the amplitude increases.
A small wave that might be unnoticable in wave height in open ocean will therefore grow as there is no place for that volume of energy to go but upward. So you'l see a tidal displacement from a tsunami over say thousands of miles whereas say the Indonesian tsunami still had a huge amount of energy and came if fast in Thailand making for a spectacular but very deadly large wave that travels much slower yet that energy will still puch the wave(s) far inland depending on the power of the earthquake. From ousands of miles away the tsunami drops in size as the energy will dissipate in the miles traveled but still carry a wallop whan it hits shore as seen in the Japanese tsunami that hit the Santa Cruz harbor, and Crescent City( and on Northward. Also there is a variable in where the most power from the earthquake its directed and the ocen floor can alter the strength and direction somewhat. Hope this helps.

How does a tsunamis start and how they develop?
Tsunamis are typically triggered by underwater earthquakes, volcanic eruptions, or underwater landslides. When these events occur, they displace a large volume of water, creating a series of powerful waves that can travel across the ocean at high speeds. As the waves approach shallow coastal areas, they slow down and their energy is concentrated, resulting in a devastating surge of water onto land.
What happens to waves as they slow down and approach shore?
As waves slow down and approach shore, their wavelength decreases while their amplitude increases. This causes the waves to become steeper and eventually break as they approach shallow water. The energy of the waves is dissipated as they break, resulting in the crashing of waves on the shore.
Can tsunamis go 500 mph?
No, tsunamis typically travel at speeds of around 500 to 600 miles per hour in open ocean, depending on the water depth. However, they slow down significantly as they approach the coast, where their speed decreases to about 20 to 30 miles per hour.

What should you do when you are approach ing a fog bank?
SLOW DOWN. If you have fog lights, turn them on.
How does wave energy impact the erosion of rock?
waves slow down as they approach the shoreline!

How do astronauts slow their spacecraft down when approaching the moon?
Astronauts use small bursts from little jets pointed in the direction of travel to slow down the ship when they approach the moon.
What is the fastest way to slow down from a freefall swoop approach?
To slow down from a freefall swoop approach, you can increase the angle of attack of your canopy by adding more rear riser input. You can also use toggle input to flare the canopy gently. Experiment with these inputs to find the right balance that allows you to slow down safely without losing too much altitude.

How fast do Tsunamis travel in the Pacific Ocean?
Tsunamis can travel at speeds of up to 500 to 600 miles per hour (800 to 970 kilometers per hour) in the open ocean, which is comparable to the speed of a jet plane. However, their speed decreases as they approach shallow waters near coastlines, causing them to slow down and increase in height.
How do waves changes as they approach the store?
As waves approach the shore, their height increases due to the decrease in water depth. This causes the waves to slow down and eventually break, transferring their energy to the shore through swash and backwash. The waves also refract, or bend, as they interact with the bathymetry of the seafloor near the shore.
How should you approach an intersection with a flashing yellow light?
Approach an intersection with a flashing yellow light with caution. Slow down, be prepared to yield to oncoming traffic, and proceed with care.
Do dating sites like plenty of fish slow down a computer?
No,visiting websites even when they set cookies or store temporary files don't slow computers down. if a website exploits a security flaw it could execute code that would slow down a computer.
