Richter scale
Richter scale is an open-ended scale that gives an idea of the amount of energy released during an earthquake and is based on the amplitudes (half the height from wave-base to wave-crest) of seismic waves at a distance of 61 miles (100 km) from the epicentre. The Richter scale is logarithmic, where each step of 1 corresponds to a tenfold increase in amplitude. Because larger earthquakes produce more waves, an increase of 1 on the Richter scale corresponds to a 30-fold increase in energy released. Named after Frank Richter, an American seismologist.
