P-waves (P stands for primary) are compressional earthquake waves ... waves travel along the Earth's surface. Two examples of surface waves are Rayleigh waves and Love waves.

The diagrams show what happens when P waves and S waves pass through the Earth. S waves do not pass through the Earth's core S waves cannot pass through the liquid outer core, but P waves can.

All available three-component time-series for the 12-month span between 2005 November 1 and 2006 October 31 have been cross-correlated to yield estimated empirical Rayleigh and Love wave Green's ...
