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).

地震的规模、深度和震级各不相同。其中绝大多数都是沿着主要板块边界蒸发的，主要是对构造力的反应。然而，与工业活动有关的板内地震（也称为“诱发地震”）的数量越来越多，频率和规模越来越大。其中一些诱发事件是由废水处理引发的，而另一些则与页岩气地层的多级水力压裂作业有关，最明显的是在加拿大西部沉积盆地（WCSB）。
