Rivka Galchen, Letter from Oklahoma: Weather Underground: The arrival of man-made earthquakes. The New Yorker, 13 April 2015. “Until 2008, Oklahoma experienced an average of one to two earthquakes of 3.0 magnitude or greater each year. (Magnitude-3.0 earthquakes tend to be felt, while smaller earthquakes may be noticed only by scientific equipment or by people close to the epicenter.) In 2009, there were twenty. The next year, there were forty-two. In 2014, there were five hundred and eighty-five, nearly triple the rate of California. Including smaller earthquakes in the count, there were more than five thousand. This year [2015], there has been an average of two earthquakes a day of magnitude 3.0 or greater.”
