Despite all the talk about the uptick in earthquake activity, and speculation that 2012 would be very active due to the December 21st 2012 Mayan Calendar end date, 2012 actually turned out to be a below average year for 5.0+ magnitude earthquakes with a total of 1774 earthquakes for an EQPD rate of 4.84.During the study period (October 2004-present) the average EQPD rate is 5.27. 2012 had 582 fewer 5.0+ magnitude earthquakes than 2011, 74 fewer 6.0+ earthquakes, and two fewer 7.0+.

This concludes the report for December 2012.
