of energy released during an earthquake. It may be expressed using several magnitude scales. One of these‚ Used in Southern California‚ is called the Richter scale. To calculate magnitude‚ the amplitude of waves on a seismogram is measured‚ correcting for the distance between the recording instrument and the earthquake epicentre. Since magnitude is representative of the earthquake itself‚ there is thus only one magnitude per quake. Taking the Lawton earthquake of 1998 APR 28‚ as an example
