Induced Seismicity

Some of the most attention-grabbing headlines of the first half of the 2010s are related to oil and gas operations and the potential for induced seismicity. Emotions ran high as different stakeholders from government, industry, and the broader community came to terms with the possibility that human operations were affecting the stability of Earth’s crust. Induced seismic events are not new. However, the correlation or potential causation between conventional drilling, unconventional drilling and stimulation, and disposal and injection operations entered the spotlight, and researchers now have a better understanding of how the energy sector affects the subsurface forces beneath our feet. This unit closes with a more holistic look at the public concerns about oil and gas operations, particularly hydraulic fracturing.
