In a recent study of the magnitude 5.0 earthquake near Prague, Oklahoma in 2011, the USGS says, “Historically, earthquakes in the central United States have been uncommon. Yet in the year 2011 alone, numerous moderate-size earthquakes occurred in Colorado, Texas, Oklahoma, Ohio and Arkansas. Many of these earthquakes occurred near waste-water injection wells, and some have been shown to be caused by human activities.” Read more of the study here.
