• A seismograph is an instrument which can record the seismic waves.
• It contains a metal rod or a pendulum which can vibrate as the earthquake occurs.
• The metal rod is attached to a pen which records the waves on the paper.
• Scientists study these waves and then construct a map of the earthquake.
• This also helps them in determining the power of the earthquake.
