How unusual is the recent pattern of earthquakes in California?

Within the last month there's been a 6.9 off the Northern California coast which I did not feel, a 4.4 near Westwood which I felt, a 5.1 near La Habra which I felt, and a swarm of aftershocks (?) of the La Habra earthquake which I haven't felt. That seems like an unusually large number of earthquakes to me. Has anyone crunched the numbers to find out if the earth has been shaking in California more than usual?
