seismograph
It's called a seismograph. I just finished learning about that in Science class.
surface waves produces the most severe ground movement because its on the surface of the earth
its called a seismograph
Seismographs cannot measure volcanoes. When you research about seismographs, it may show thing about volcanoes. This is because right before a volcano erupts, it can cause little earthquakes and seismographs measure earthquakes!
A seismograph is an instrument that measures the seismic wave activity in an area. According to Wikipedia, Seismometersare instruments that measure and record motions of the ground, including those of seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of seismic waves allow seismologists to map the interior of the Earth, and locate and measure the size of these different sources. A seismic wave, according to wikipedia is, "Seismic waves are waves of force that travel through the Earth or other elastic body, for example as the result of an earthquake, explosion, or some other process that imparts forces to the body. Seismic waves are also continually excited on Earth by the incessant pounding of ocean waves (referred to as the microseism) and the wind."Seismograph is another Greek term from seismós and γράφω, gráphō, to draw. It is often used to mean seismometer, though it is more applicable to the older instruments in which the measuring and recording of ground motion were combined than to modern systems, in which these functions are separated. Both types provide a continuous record of ground motion; this distinguishes them from seismoscopes, which merely indicate that motion has occurred, perhaps with some simple measure of how large it was.

What does a seismograph use to record the drums vibrations
First P waves, seismic waves that compress and expand the ground like an accordion. Then S waves, seismic waves that vibrate from side to side as well as up and down. And finally Surface waves, they move more slowly than P waves and S waves. But they can produce severe ground movements.
