magnitude of past earthquakes in the area
The depth of the earthquake focus is not a factor in calculating the moment magnitude of an earthquake. Instead, factors include the seismic moment (the total energy released), the rigidity of Earth's crust, and the amount of slip along the fault.
An earthquake's magnitude is a measure of how strong it is
The moment magnitude uses seismographs plus what physically occurs during an earthquake.

the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
to rate an earthquake
The strength of an earthquake is measured by its magnitude, which indicates the amount of energy released at the earthquake's source. Earthquake magnitude is typically reported on the Richter scale or the moment magnitude scale.
The magnitude of the 2011 earthquake in Christchurch, New Zealand, was 6.3 on the Richter scale.
to rate an earthquake
The size of an earthquake is defined by its magnitude, which measures the energy released at the source of the earthquake. Magnitude is typically reported on the Richter scale or the moment magnitude scale.
The Chilean earthquake that occurred in February 2010 had a moment magnitude of 8.8.
