Earthquake_wave_paths.png (300 × 250 pixels, file size: 13 KB, MIME type: image/png)

Cross section of the whole Earth, showing the complexity of paths of earthquake waves. The paths curve because the different rock types found at different depths change the speed at which the waves travel. Solid lines marked P are compressional waves; dashed lines marked S are shear waves. S waves do not travel through the core but may be converted to compressional waves (marked K) on entering the core (PKP, SKS). Waves may be reflected at the surface (PP, PPP, SS).

Seismographs detect the various types of waves. Analysis of such records reveals structures within the Earth.
