Detailed explanation-1: -The two main types of waves are body waves and surface waves . Body waves can travel through the Earth’s inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.
Detailed explanation-2: -There are two different types wave produced by an earthquake: body waves and surface waves. Body waves are seismic waves that travel through the body of the earth. Body waves are reflected and transmitted at interfaces where seismic velocity and/or density change, and they obey Snell’s law.
Detailed explanation-3: -Introduction. Earthquakes not only release seismic wave energy but also generate other types of energy such as rotational kinetic energy, gravitational potential energy (GPE) and elastic strain energy (Dahlen 1977). Of those, the kinetic energy of rotation is the smallest energy induced by earthquakes (Dahlen 1977).
Detailed explanation-4: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
