The undersea wave can move at up to 500 mph (800 kph). But as the tsunami moved inland, its forward speed was as slow as about 10-30 mph (15-45 kph) depending on the terrain, so some people were able to outrun it once they saw it. But the warning time to recognize the threat, and to find an escape route, was usually measured in a few seconds.

Can seismographs stations in Europe or Asia or anywhere in the world detect the P-wave or S-waves?
yes because the waves sometimes travel very fast
Why do earthquake waves travel fast in the crust but slowest in the interior of the earth?
Earthquake waves travel fastest in the interior of the Earth, as speed of waves increases as we go inside the Earth. The speed of a wave depends on the properties of the medium it travels in. The wave propagates faster in the denser and heavier core.
How do sound waves effect plants?
Sound waves are waves of energy created by the vibration of a source (vibrating phone, vocal cords, etc.) that travel through a medium (air, water, solids). This means that the plant will get extra energy aside from sunlight that will make it grown at faster rates. It depends how fast those sound waves travel (frequencies) and how loud the sound waves are. Hope that answers your question!
Why can't secondary waves travel through liquids or gases?
S waves can only pass through solids. They cannot pass through liquids (e.g. water, molten rock).
Are s-waves slow or fast?
s-waves are slower they always occur after p-waves
How do sound waves travel compared to light waves?
light waves fast
How fast do these waves travel?
really fast man. like super fast.
How fast do Transverse waves travel?
3x10^8
How fast to brain waves travel?
About 120m per second
How fast does theRadio waves travel?
Radio waves travel at the speed of light 300 Million meters/second, 300e6 meters/second
What are similarities of light and sound?
They both travel in the form of waves, and they both travel very fast.
What waves travel the fastest?
P-waves travel the fastest. This is also knows as a Primary waves, or compressional wave. P-wave stravel twice as fast as an S-wave

How fast do sound waves travel near sea level?
lool
How fast can sound waves travel in copper wire?
200m/s
How fast do waves of radiation travel through space?
About 30km/hour
Why is diffraction of sound waves more easily observed than diffraction of light waves?
sound waves travel fast than light waves
