What is the difference between a primary wave and a secondary wave?

Primary seismic waves (also called P-waves) are a type of ground motion most commonly associated with earthquakes, though the waves are also caused by large explosions (nuclear tests) and would be expected from an asteroid impact. For a primary seismic wave, the motion of the ground is caused by a series of compressions and decompressions in which the ground at any point is moving on an axis which passes through the epicenter, while each individual wave front is spherical around the epicenter. Since solids (such as rock) are not readily compressible by significant amounts, the vibratory movement is very slight and the wave travels very rapidly. As a consequence, P-waves travel faster than Secondary waves (S-waves) also generated by the same seismic event. Consequently, P-waves are the source of the deep rumbling sound which can be heard at the beginning of an earthquake just before the far more destructive S-waves arrive.


How far is an observer from an earthquake epicenter is he or she observed a P wave 8 minutes after the earthquake?

14,4oo km away. i think. check calculations to be sure.


Are primary seismic waves slower than secondary waves?

Primary waves are called so because they are the first to arrive, and secondary waves are called so because they arrive second. Based on this logic I would say no. There is in fact a marked difference, which is used to tell how far away the epicenter is from a particular seismograph.


Approximately how far is an observer from and earthquake epicenter if he or she observed a p wave 8 minutes after the earthquake?

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.
