The three waves that are shown on a seismogram in order are P waves, S waves, and surface waves.
A record of the waves co used by an earthquake is called seismogram the diagram above shows simplified seismogram
A seismograph is used to delete seismic waves under the surface of the Earth. It helps seismologists to determine the locations of earthquakes.
Earthquakes are caused when energy is released as the lithosphere (crust and upper mantle) of the Earth moves. Energy is emitted in the form of waves. There are different types of waves, some move faster, slower, sideways, or up and down. A seismograph records these waves on a seismogram.

The insrument that is used for scientist to study earthquakes is a seismogram
You can learn the location of the earthquakes epicenter.
a seismograph records the pattern of shcok waves on a revolving drum of paper.ans tracing on the paper is known as seismogram
"Shake, Rattle, and Roll". But seriously folks, it's called a "seismogram".
Assuming you mean 'seismogram' - it's a printout from a seismometer... which is an instrument that measures earthquakes.
