When you're 10 or 20 miles away from the origin of an earthquake, the P-waves get to you a little bit before the S-waves. Which of the following best explains this?
(A) When an earthquake happens, P-waves are produced before the S-waves.
(B) P-waves travel through the ground faster than S-waves.
(C) S-waves take a longer, curved path through the Earth to get to you.
P, Primary, or Compressional waves travel the fastest (~6 km/sec in the upper crust). They cause the matter to oscillate forward and backward, parallel to the motion of the seismic wavefront. P waves push (compress) and pull (dilate) the rock that they pass through.
