A seismograph is an instrument used to measure movement of earthquake. It measures the seismic waves of that area.
A seismograph measures the vibrations made when earth layers "move", such as the waves of movement during an earthquake.Frequency and amplitude of seismic waves.
The first waves to arrive at a seismograph station are primary waves, or P waves.
Seismic waves are measured by seismographs, geophones, hydrophones and accelerometers.
Primary waves
A seismometer or seismograph
earthquakes are measured by seismic waves so scientists use a seismograph. there are a bunch of seismographs at a station and each one records the same stuff according to the p, s, and surface waves.

It's called a seismograph. I just finished learning about that in Science class.
the ground movement caused by seismic waves
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.

Humorous answer: A seismograph never answers; it just waves.
The first waves to arrive at a seismograph station are primary waves, or P waves.
Are they not called fissures RESPONSE TO: Are they not called fissures They are so not called fissures. Fissures are way different from what the question is. Now think, what type of movement do you feel when an earthquake happens. Of course, SHAKING.
