The aftermath of an earthquake, Golcuk, Western Turkey. 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. 1  Earthquakes measuring just one or two on the scale are very common and can happen everyday in places like San Francisco. 2  These earthquakes are so small that people cannot feel them, they can only be picked up by a seismometer.
