Induced seismicity
The U.S Geological Survey (USGS) has produced a one-year 2017 seismic hazard forecast for the central and eastern United States from induced and natural earthquakes that updates the 2016 one-year forecast; this map is intended to provide information to the public and to facilitate the development of induced seismicity forecasting models ...The white circles mark the locations of the six clusters investigated in this study. The induced seismicity in western Canada is mostly limited to a zone of moderate tectonic moment rate of ∼10-20 × 10 5 Nm/m 2 /year and relatively high injection volume (see Figures S1 and S8). The tectonic moment rates are calculated using a shear modulus ...The filling of surface reservoirs with water also causes earthquakes. This so-called “reservoir-induced” seismicity has been documented ever since large reservoirs were constructed. The first well studied example accompanied the impoundment of the Colorado River, USA by the Hoover Dam to form Lake Mead (Carder 1945 ).

But they also pose a whole new set ...The Salamon-Linkov method (as previously described) is currently used to simulate mining-induced seismicity and is a principal vehicle for providing hazard assessment. However, the fact that the method is unable to simulate volumetric sources and is restricted to a single elastic material is somewhat unsatisfactory.The results can provide important evidence about the triggering mechanism of induced seismicity. In addition, we also determined the local stress state using the focal mechanism solutions and estimated the pore pressure changes required to trigger the fault slip.

In response to the Dutch Safety Board (Onderzoeksraad voor Veiligheid = OVV) ...The seismicity distribution suggests a statistically significant association with injection, and event migration can be described by a hydraulic diffusivity of ~0.2 m 2 /s. A comparison between daily seismicity rate and analytical stress evolution inferred from daily injection volumes implies that pore pressure diffusion largely controls ...A critically stressed fracture will slide in response to the increase in fluid pressure inside the fracture while impounding, which will trigger induced seismicity.

In general, two types of mining-induced seismic events exist (Gibowicz and Kijko 1994).The first type results from the formation of fractures near the faces, e.g., roof fracturing (Bischoff et al. 2010; Iannacchione et al. 2005; Xu et al. 2015; Zhang et al. 2020) or punching of a remnant pillar (Alber et al. 2009).

We infer from the spatial and temporal pattern of seismicity that the seismicity at The Geysers is induced by geothermal production activities. With the expansion of power production by approximately 70% in 1979-1980, seismic activity has developed near the new production areas. Seismicity has also expanded northwestward of the present ...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].
