The Love and Rayleigh waves (collectively known as surface waves) are the slowest moving but most damaging of the seismic waves.
Seismic waves that travel along the outer layer of Earth, show the highest amplitudes on a seismogram, and are the most destructive. Smaller earthquakes that follow the main earthquake. This magnitude scale is a measure of the energy released and is determined from the amplitude of the largest seismic wave. It does NOT directly measure the extent of building damage.
