In August 2009, an earthquake of magnitude 6.1 hit Honshu, Japan. The Richter scale formula measures and records the movement of the Earth at the epicenter of an earthquake. This number is then used to calculate the energy that has been released. This formula was developed by Charles Richter, in the year 1935. It was prepared from the logarithm of amplitude of waves, that were recorded by seismographs. From 1935 until 1970, the earthquake magnitude scale was the Richter scale, a mathematical formula invented by Caltech seismologist Charles Richter to compare quake sizes. The Richter Scale was replaced because it worked largely for earthquakes in Southern California, and only those occurring within about 370 miles of seismometers.The intensity of an earthquake will typically measure between and on the Richter scale.
