Earthquakes come in all sizes, depths and magnitudes. The vast majority of them transpire along major plate boundaries, largely in response to tectonic forces. However, a growing number of intra-plate earthquakes in connection with industrial activities (also known as ‘induced earthquakes’) are being reported at increasing frequencies and sizes. Some of these induced events are triggered by wastewater disposal, while others have been linked to multistage hydraulic fracturing operations on shale gas formation, most notably in the Western Canada Sedimentary Basin (WCSB).
