Do seismic waves travel along the Earth’s surface?
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 radiate seismic energy as both body and surface waves.
Which seismic waves stay on Earth’s surface?
There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.
Do surface waves travel through solids?
Surface waves travel along the surface. There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
Where do seismic waves travel slowest and fastest?
Surface waves travel along the ground outward from an earthquake’s epicenter. Surface waves are the slowest of all seismic waves. They travel at 2.5 km (1.5 miles) per second.
