Seismicity refers to the geographic and historical distribution of earthquakes. Induced seismicity is a seismic event resulting from human activity, and can be caused by industries such as mining, dam impoundment and natural gas development.The seismic activity's exact cause remains undetailed, but the possibilities range from tectonic plate movements and volcanic activity to human activities like mining and reservoir-induced seismicity.Thus, observed seismicity must be attributed to a different mechanism, which we assume is poroelastic contraction and associated horizontal stress reduction, Δσ h, induced in the reservoir [Segall and Fitzgerald, 1998]. As a result, the resolved shear stress on faults is increased and, if this exceeds the concurrent strength increase, the ...Human-induced seismicity, in particular associated with oil and gas operations, has been observed for almost a century. One of the first documented examples was in the Goose Creek Field in Texas, where subsidence of an area following the contours of the oil field was accompanied by surface faulting and small earthquakes (Pratt & Johnson, Reference Pratt and Johnson 1926).

Induced seismicity is typically earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth's crust. Most induced seismicity is of a low magnitude.For induced seismicity, however, this network is developed in quite an irregular and inconsistent way, driven by local requirements for different operators and industries. Consequently, the network's detection and location capabilities have been, and still are, highly variable. This significantly hampers the identification of the full extent ...Injection of fluid into the crust can generate seismicity, with source mechanisms similar to natural earthquakes and occasionally large enough to cause damage (1-6).Induced seismicity is generally regarded as a manifestation of the effective stress principle, where the increase in pore pressure reduces the effective normal stress and brings a preexisting fault or intact rock mass to failure ().

Dec 16, 2016 · Fluid injection–induced seismicity has become increasingly widespread in oil- and gas-producing areas of the United States (1–3) and western Canada.It has shelved deep geothermal energy projects in Switzerland and the United States (), and its effects are especially acute in Oklahoma, where seismic hazard is now approaching the tectonic levels of parts of California. Induced seismicity in geothermal projects appears to be related to both net fluid balance considerations and temperature changes produced in the subsurface. Different forms of geothermal resource development appear to have differing potential for producing felt seismic events. High-pressure hydraulic fracturing undertaken in some geothermal ...
