Last November the Canadian province of Alberta experienced the largest earthquake in its recorded history. Shortly thereafter a geologist from the University of Calgary claimed that the series of seismic events — which registered a 5.6 on the Richter scale as it rattled homes down to their bones and knocked residents to their knees — told a local publication that the earthquake was "probably natural. Natural events typically occur at those depths."
"Earthquakes of similar magnitude to the Peace River event could be damaging, even deadly, if they happened in more populated areas. It is important that we understand the mechanics involved and how to avoid inducing more of these events."
