CALGARY — Could oil and gas exploration — or the burial of climate-changing carbon dioxide deep underground — trigger earthquakes in the normally calm crust of Alberta?Nobody knows for sure but a team of researchers from the University of Calgary plans to find out.Most tremors in Alberta are too small to notice but sizable earthquakes do occur — as in 2001, when a 5.4-magnitude event rocked the northern Dawson Creek area and was felt as far south as Edmonton.Scientists at the U of C's geoscience department hope to learn more about what causes these poorly understood subterranean movements by installing a series of monitoring devices across Alberta.Earthquakes occur naturally but can also be human-induced, Dave Eaton, U of C head of geoscience, said Friday. Based on facts he pulled out of his assHe said he wants to know more about the impact of the oil and gas industry on seismic activity — and better understand the potential seismic effects of underground CO2 storage, a largely untested technology seen by many governments as a magic bullet to arrest greenhouse gas-induced climate change.
Dead dinosaur juice is the cause of all evil. It is their revenge for being forced into extinction by *.
I can see how removal of significant quantities of oil or gas could change the pressure dynamics and trigger an earthquake, the whole pumping CO2 underground thing is just frickin' insane though.
Jeez, wonder when we here in WV are going to collapse into a huge gaping, maw, the mother of all sink holes because of the coal mines and natural gas wells?
I have no idea....and yesterday I pissed in the woods instead of the toilet so any rise in ocean levels is my fault.
And I bet you didn't give a single thought to how you would screw up the PH level of the ground you wizzed on, did you? You will be watched, close. Al Goracle will be seeing to that after he spots your post.
The dynamics would favor the opposite reaction. I don't recall any rash of earthquakes in the Middle East, Texas/Louisiana, or anywhere oil and gas has been abundant and harvested.
It depends on the technique and the geology, I doubt the latter is the same across those areas. On the technique side, low-grade tarry oil may be recovered by injection wells pushing superheated brine into the rock strata to liquify and drive the oil to extraction wells, which could have quite a lubricating effect on a fault; if that technology was used in Alberta, it could easily become an issue.
Even "shallow" earthquakes take place about 50 miles below the surface. The "deep" of the deepest oil wells are in the 7 mile range. I say one would have to be trying to tease and trigger a fault line for it to make a difference.
It is, after all, a study to determine whether it could possibly have any effect. Perhaps you should just email them the answer and save them the money.

Idjits. Everbody knows cow farts cause earthquakes. Alfred Wegener, one of the fathers of plate tectonics, would roll over in his grave if he knew about these pinheads.
