Question

Estimate, to the nearest tenth of a minute, the times that P-waves and S-waves firstarrived at each recording station (seismograph location) in Figure 4. Then, subtract Pfrom S to get the S-minus-P time interval:
First P arrival First S arrival S-minus-P

Answer 1

P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth.

S waves have a larger amplitude than P waves and cause the ground's surface to move both vertically and horizontally, making them more dangerous. Surface waves, which move slowly, are the last to arrive. P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter. Points of solid media move back and forth perpendicular to the wave's direction of propagation due to S waves, also known as shear or transverse waves. As the wave passes, the medium is sheared first in one direction and then in the opposite direction.
