The kind of seismic waves travel through the earth are Congressional longitudinal waves and shear transverse waves.

Explanation:

There are two kinds of seismic waves and they are the Congressional longitudinal waves and shear transverse waves.They are called the P waves and S waves when they pass through the earth. P waves are the primary because they are the fastest waves whereas S waves are the secondary since they are slowerP waves move as alternate compressions and dilations along the side of propagationS waves move as alternate compression and transverse motion along the perpendicular side of propagation.
