2000 KPH on open water and when it reaches Sumatra it slowed to 1200 KPH
The wave would slow down as it approaches the shore.
The speed of a tsunami wave decreases as it approaches the shore due to the shallowing of the ocean floor, causing the wave to compress and slow down. However, the height of the wave may increase as the energy in the wave is concentrated, leading to higher waves onshore.
The top speed of a tsunami is 900 kilometers per hour (600 mi/hr) and the top speed of a cheetah is 120 kilometers per hour (75 mi/hr). Therefore, the average speed of a tsunami is faster than the top speed of a cheetah.
In deep ocean water, the speed of a tsunami can exceed 500 mph but the wave height may be only a few feet. As the tsunami approaches shallow water and the sea floor rises, the speed decreases while the wave height increases significantly. This is why tsunamis can cause devastating flooding and destruction when they reach the coastline.
A tsunami, like the category you posted it in?
As a tsunami wave approaches the shore, its speed decreases due to the wave energy being compressed into a smaller space. This leads to an increase in wave height and impact force when the tsunami hits the coastline.
Yes the speed of a wave does depend on the source.
800 kmh
50,000 people per hour.
The wave would slow down as it approaches the shore.
Huge.
20 miles per hour
23 mph

A tsunami wave can be detected by a wave gauge and pressure monitors.
The top speed of a tsunami is 900 kilometers per hour (600 mi/hr) and the top speed of a cheetah is 120 kilometers per hour (75 mi/hr). Therefore, the average speed of a tsunami is faster than the top speed of a cheetah.
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/
