Improving the monitoring and analysis of induced earthquakes

地震的大小、深度和震级各不相同。它们中的绝大多数沿着主要板块边界蒸发，主要是对构造力的反应。然而，越来越多的与工业活动有关的板块内地震（也称为“诱发地震”）正在以越来越高的频率和规模被报道。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，尤其是在加拿大西部沉积盆地（WCSB）。

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).
