However, It has had at least 17 quakes above magnitude 4 since 1970, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 1 to 5 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeStrongest in 3 yearsThe earthquake was the strongest to hit this part of the United States in over 3 years.
