Earthquakes have become more than 10 times more common in normally quiescent parts of the U.S., such as Ohio and Oklahoma, in the past few years. Given the simultaneous uptick in fracking—an oil and gas drilling technique that involves fracturing shale rock deep underground with the use of a high pressure water cocktail—it’s common to [...]
