Apparently things are moving and shaking in Oklahoma, literally. In the past 8 years earthquakes in the Sooner State have increased from 2 a year to 2 a day. Is the expansion of gas and oil exploration during that same period of time a mere coincidence? This week on Sea Change Radio, we hear from Ole Kaven, a geophysicist with the US Geological Survey. Kaven s area of expertise is human-induced seismicity, in other words, how human activity contributes to earthquakes. He talks about the work he has been doing studying the effects of carbon sequestration on seismic events, the sharp increase in Oklahoma s seismicity, and what the government and the public should know about how oil and gas industry practices could be making the earth move under our feet.
