Regulator says drilling likely triggered 4.4 temblor.

Fox Creek, Alberta:
'Location of earthquake consistent with being induced by hydraulic
fracturing operations,' says Alberta Energy Regulator spokesperson.
Hydraulic
fracturing, a technology used to crack open difficult oil and gas
formations, appears to have set off a swarm of earthquakes near Fox
Creek, Alberta, including a record-breaking tremor with a felt magnitude
of 4.4 last week.
That would likely make it the largest felt earthquake ever caused by
fracking, a development that experts swore couldn't happen a few years
ago.
Fracking operations in British Columbia's Montney shale generated
similar seismic activity of that magnitude last year, and earthquake
scientists at Ontario's Western University are still analyzing the two
events to see which is the largest. MORE
