3 main, not sure if there's other devices. (seismoscope, seismometer, ???)
there are three different seismic waves
primary waves [p waves]
secondary waves [s waves]
surface waves
three types of sesimic waves are there
A seismic wave travels through the Earth's layers, after a volcano, explosion, or earthquake. Transverse, compressional, longitude, and shear waves are all types of seismic waves after earthquakes.
Seismic waves occur when there is an earthquake.
Seismic waves are the forms of energy produced by an earthquake.
A seismic wave is created by a earthquake.
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explotion.
Seismic waves are produced by earthquakes
seismic
Longitudinal waves that are produced by earthquake are called primary waves because they are detected by seismometers before the other types of seismic waves due to their higher velocity which means they travel from the epicentre of an earthquake to the seismic station more quickly than the other types of seismic waves.

the waves caused by an earthquake are called seismic waves
P waves - compress and expand the ground like a Accordion S waves - vibrate from side to side as well as up and down Surface waves - make the ground roll like ocean waves The Earthquake is produced by each of the three types of seismic waves.
Seismic waves are produced by earthquakes, rather than the cause of them! The most damaging seismic waves are the surface waves of which there are two types. Love waves and Rayleigh waves. For more information, please see the related links and question.
A seismic wave. If the earthquake occurs under water, the seismic waves can produce waves in the water called tsunami.

seismic waves
Seismic waves are any waves that travel through the Earth. As such all earthquake waves are seismic waves, however not all seismic waves are caused by earthquakes.
