Some time in mid- to late November, geophysicist David Eaton will head into the forests around Fort St. John, Canada, and help to nestle an array of 15 seismometers onto the ground. They will spend their days listening for small earthquakes caused by oil and gas exploration in this part of British Columbia. If Eaton has his way, the seismometers will soon be joined by hundreds more, blanketing Canada as part of an unprecedented quest to probe the nation’s geology.
