The Love and Rayleigh waves (collectively known as surface waves) are the slowest moving but most damaging of the seismic waves.
Earthquakes produce two main types of waves-the P-wave (a compressional wave), and the S-wave (a shear wave). The S-wave is slower but larger than the P-wave and does most of the damage.
