Shear Wave (S-Wave) Animation Back Deformation
propagates. Particle motion consists
of alternating transverse motion.
Particle motion is perpendicular to the direction of propagation
(transverse). Transverse particle
motion shown here is vertical but can be in any direction; however Earth’s
layers tend to cause mostly vertical (SV) or horizontal (SH) shear motions. Material returns to its original shape
after wave passes. |
