Here are the averages listed on the usgs website:

8.0+ = 1
7.0+ = 15
6.0+ = 134

How far over this would we have to go before you personally would consider it strange or unusual?

Hmm…Actually I see now that I was being too vague. Those are the average number of earthquakes that occur worldwide per year according to the USGS.
