Best Answer

A seismogram is a recording of ground motion at a particular ground location, as collected by a seismometer. Multiple seismograms, taken from different locations, can be analyzed to determine the magnitude, depth and location of an earthquake.

Seismograms used to be recorded on paper by seismograph machines, but virtually all seismograms are recorded digitally, today, since computers are essential to accurately process the simultaneous readings from hundreds of seismometers.

A seismometer is a device that measures the vibrations made be earthquakes. (seismic waves) Seismic waves consist of P(primary) waves LONGITUDIUAL think of them as "PUSH AND PULL" waves because they move buildings up or down. The other wave is the s(seconday) waves TRANVERSE think of them as "SHAKE TO SIDE" waves because they shake buildings from side to side.

Both waves are very dangerous and can do a lot of damage and a seismometer detects this.

I hope this helped!

A seismometer is a device which measures the amplitude and frequency of seismic waves and also the acceleration of the ground surface during an earthquake.
A seismometre is what is used to record the amount of seismic energy that is realised in an earthquake
