The average number of earthquakes of a certain size is the average since they have been taking records. Some years there will be more, some years less. To have any statistical meaning where it comes to earthquakes we don't even possess enough data yet and even if we did, no computer yet exists that could run the models. Same thing with the weather.
It's pure arrogance to think that anyone can predict much of anything on either topic.
For instance today's earthquake was epicentered at the exact same spot expected for one in that area. Same thing in regards to the ones at the New Madrid. The one in Colorado is also not in an unexpected location no matter how may spread that falsehood. I guess some just like to advertise their lack of study or knowledge or do it on purpose to scare people for fun.
Seismic Hazard Map for that area showing that this was were it would be expected to happen historically.
Some truthful information on the Virginia Quake as opposed to the fabricated stuff making the rounds on ATS.
The Virginia earthquake of 2011 August 23 occurred as reverse faulting on a north or northeast-striking plane within a previously recognized seismic zone, the "Central Virginia Seismic Zone." The Central Virginia Seismic Zone has produced small and moderate earthquakes since at least the 18th century. The previous largest historical shock from the Central Virginia Seismic Zone occurred in 1875. The 1875 shock occurred before the invention of effective seismographs, but the felt area of the shock suggests that it had a magnitude of about 4.8. The 1875 earthquake shook bricks from chimneys, broke plaster and windows, and overturned furniture at several locations. A magnitude 4.5 earthquake on 2003, December 9, also produced minor damage.
Link to the Seismic Hazard Map for the one in Colorado, once again showing it DID NOT OCCUR IN AN UNEXPECTED AREA!
NOTE: To see these maps you have to click on the link and look at them.
Folks, ignore the fear mongers who are spreading false information. People who fabricate stuff to scare people are not your freinds.

It is not the earthquakes in areas with faults or volcanoes that should be payed attention to, as there will always be earthquakes.
Rather it is the ones that are in what would be considered geologically stable areas that bear for us to pay attention to, as they are out of the ordinary and should be of concern. The 2 that the OP mentioned, the one in Colorado/New Mexico, and the one in Virgina, those are something that everyone should wake up and pay attention to, as there is no faults in that area, infact looking at the geological maps they do not make sense as to why they occured.
