Question

How does a seismograph generate a seismogram?

Answer 1

During an earthquake, the seismometer remains still while the case around it moves with the ground shaking. ... Seismographs can detect quakes that are too small for humans to feel. During an earthquake, ground-shaking seismic waves radiate outward from the quake source, called the epicenter.

• 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.
