The speed of an earthquake wave is not constant but varies with many factors. Speed changes mostly depending on depth and rock type. P waves travel between 6 and 13 km/sec. S waves are slower, which travel between 3.5 and 7.5 km/sec.
Based on the average speed of a P-wave (6 km/s), if the observer detected the P-wave 8 minutes after the earthquake, they would be approximately 2880 km away from the epicenter. This calculation assumes the P-wave travelled directly through the Earth without any barriers altering its speed.
A seismic wave.
therre is more than one wave, it could be a surface wave, or an s wave or p wave
a tsunami is a tidal wave caused by an underwater earthquake :]
A body earthquake wave that cannot penetrate the Earth's core is called a P-wave. P-waves are the fastest seismic waves and travel through the Earth by compressing and expanding the rock. While they can travel through the Earth's core, their speed and path are altered, causing them to refract instead of penetrate it.
Seismic wave velocity is mostly dependent on the material they travel through (things like magnitude do not affect wave velocity). As the earth is relatively uniform, there is virtually no deviation in earthquake 'speed'. (Wave velocity will differ depending on phase, depth, etc. - but that's different.)
the sound wave
Wavelength = (speed) / (frequency) = (5,000) / (10) = 500 meters = 0.5 km.
Based on the average speed of a P-wave (6 km/s), if the observer detected the P-wave 8 minutes after the earthquake, they would be approximately 2880 km away from the epicenter. This calculation assumes the P-wave travelled directly through the Earth without any barriers altering its speed.
it creates a earthquake!
A tidal wave is caused by an earthquake.
The Secondary or S-wave.
A mechanical wave.
The first shock wave of an earthquake is known as the P-wave or primary wave. It is the fastest seismic wave and can travel through both solid and liquid materials. P-waves are responsible for the initial jolt felt during an earthquake.
The P wave
It can be either.
An earthquake.
