Other waves, the P waves (pressure waves) are able to travel through the liquid outer core. When the waves once again reach the crust, they cause smaller earthquakes. While the rippling effect caused by S waves can only be felt where the waves can reach without crossing the outer core, the pressure of the P waves can be felt clear on the other side of the Earth.
