Are Seismic Waves Sound Waves?

As the Earth shakes at the surface, seismic waves are pulsing through the layers of Earth below, invisible to human eyes and ears but observable as sound waves. Sound waves that can be recorded, even monitored, to provide advance warning of a coming seismic event.

What is the difference between sound waves and seismic waves?

Sound is a form of energy that results when vibrating materials produce waves that move through matter. Earthquakes are vibrations in the earth that release the (potential) energy stored in rocks (due to their relative positions and consequent pressure). Earthquakes create seismic waves.

What type of waves are seismic waves?

Types of Seismic Waves

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.
