The power of an earthquake is measured using a seismometer.

A seismometer detects the vibrations caused by an earthquake. It plots these vibrations on a seismograph.

The strength, or magnitude, of an earthquake is measured using the Richter scale.

The Richter scale is numbered 0-10 with 10 being the greatest strength or magnitude.
