During a seismic event, a monitoring station detects two types of body waves traveling through the Earth's crust: primary (PPP) waves, which are longitudinal, and secondary (SSS) waves, which are transverse.
Compare the motion of the ground particles during the passage of an SSS-wave to their motion during a PPP-wave, clearly relating your description to the direction of energy transfer.
