Seismic waves are vibration which travel through the ground. The different types can be divided into to types, those which travel through the rock (body waves) and those which travel along a boundary such as the earth?s surface (surface waves). The distance travelled will depend on the size of the source of vibration (e.g. blast) and the nature of the rock through which the waves travel.
A long-period WAVE caused by an underwater seismic disturbance or volcanic eruption.
A vibrational disturbance in the Earth that travels at speeds of several kilometers per second. There are three main types of seismic waves in the earth: (fastest), (slower), and surface waves (slowest). Seismic waves are produced by earthquakes.
waves sent out during an earthquake by faulting and spread through the solid Earth
the waves generated from an earthquake.
(pronounced SIZE-mic waves) vibrations that move outward from the focus of an earthquake, causing the ground to shake.
Waves of energy emitted at the focus of an earthquake.
Shock waves travelling through the Earth, usually caused by an earthquake. Waves
Waves that pass through or around the Earth caused by an earthquake.
A form of sound waves that travel away from the source of an earthquake. There are several types of seismic waves, but S-waves and P-waves are the most commonly measured and recognized.
