Gutenberg-Richter law
The Gutenberg-Richter Law describes the relationship between the magnitude of earthquakes and their frequency. Essentially, it states that smaller earthquakes happen much more often than larger ones. Specifically, for each increase in magnitude, the number of earthquakes decreases exponentially. For instance, if one magnitude 7 earthquake occurs, there will be about 10 magnitude 6 earthquakes and approximately 100 magnitude 5 earthquakes. This law helps seismologists understand and predict the occurrence of earthquakes, providing insight into the distribution of seismic activity over time and helping improve safety and preparedness efforts.

The Gutenberg-Richter Law is a statistical relationship that describes the frequency of earthquakes in relation to their magnitude. It suggests that smaller earthquakes are much more common than larger ones. Specifically, for every increase of one unit in magnitude, the number of earthquakes diminishes by about ten times. For example, if there are 100 magnitude 5 earthquakes, there would be about 10 magnitude 6 earthquakes, and 1 magnitude 7 earthquake. This principle helps scientists understand seismic activity and assess earthquake risks in different regions.
