When two blocks of rock or two plates are rubbing against each other, they stick a little. ... When the rocks break, theearthquake occurs.

The power of an earthquake is measured using a seismometer. ... It plots these vibrations on a seismograph. The strength, or magnitude, of anearthquake is measured using the Richter scale. The Richter scale is numbered 0-10.
