Fact Check: "Fracking for LNG is linked to increased earthquakes in B.C."
What We Know
Fracking, or hydraulic fracturing, is a method used to extract natural gas by injecting high-pressure fluid into underground rock formations. Recent reports indicate a correlation between fracking activities and increased seismic activity in British Columbia (B.C.). The British Columbia Energy Regulator has acknowledged that several earthquakes, including those with magnitudes ranging from 3.1 to 4.7, were induced by fracking operations in the northeastern part of the province (source).
John Cassidy, a seismologist with Natural Resources Canada, confirmed that the regulator has strengthened its oversight of "induced" seismic activity following these events. The regulator's measures include requiring immediate cessation of operations if a quake of a certain magnitude occurs near fracking sites (source). Over the past year, there have been multiple earthquakes recorded in the region, with significant numbers occurring in close proximity to fracking operations (source).
Analysis
The evidence linking fracking to increased seismic activity in B.C. is supported by credible sources, including the British Columbia Energy Regulator and Natural Resources Canada. The regulator's acknowledgment of induced seismicity and the implementation of stricter monitoring and operational guidelines lend weight to the claim that fracking is associated with increased earthquakes in the region (source).
However, some commentary from industry proponents argues that while fracking can induce small earthquakes, these events are typically minor and do not cause structural damage. For instance, Stewart Muir, in a commentary piece, suggests that the seismicity associated with fracking is manageable and that the industry operates under strict regulations to mitigate risks (source). This perspective highlights a potential bias, as it comes from a source that may have vested interests in promoting the LNG industry.
Additionally, other reports have documented adverse effects of fracking-related seismic activity, including impacts on livestock and ranching operations in the area, which further complicates the narrative (source). This indicates that while the earthquakes may not be large enough to cause significant damage, they can still have real-world consequences for local communities.
Conclusion
The claim that fracking for LNG is linked to increased earthquakes in B.C. is True. The evidence from regulatory bodies and scientific observations supports the assertion that fracking activities can induce seismic events. While the magnitude of these earthquakes may often be low and not typically damaging, the correlation is clear, and regulatory responses indicate recognition of the associated risks.
