Primary (compressional) waves. P-waves are the fastest waves created by an earthquake. They travel through the Earthâs interior and can pass through both solid and molten rock. They shake the ground back and forth â like a Slinky â in their travel direction, but do little damage as they only move buildings up and down. Secondary (shear) waves.
