Richter magnitude scale -- The Richter magnitude test scale (or more correctly local magnitude ML scale) assigns a single number to quantify the size of an earthquake.
This magnitude, which came to be known as the Richter scale, means that when earth movement increases arithmetically, an earthquake's destructive power increases exponentially.
While the new work will not help seismologists predict earthquakes with any greater accuracy, it does help them estimate the likelihood of future damage, since an area with many smaller quakes can be tagged as one likely to experience a larger quake.
