However statistical analysis is limited to events above the completeness magnitude mc, which estimation may significantly vary depending on the employed method. To avoid potential biases and optimize the data exploitable for ...With the increase in mining depth, coal bursts have become a major challenge in the safe mining of steeply inclined and extra thick coal seams (SIETCSs). Based on a typical mining induced seismicity triggered coal burst (MSTCB) in SIETCS, a large-scale numerical model was developed using the Universal Distinct Element Code. The numerical model was calibrated and validated by laboratory results ...

Until now, the way that the risk due to induced seismicity has been managed is very different and has been largely driven by Earth science: implicit assumptions are made regarding the exposure and its fragility, and the risk is then mitigated through schemes to either reduce the hazard at the location of the buildings by either relocating the ...

Seismicity associated with reservoir impoundment and seasonal variation in water level is termed reservoir-induced seismicity (RIS), and is a well-known phenomenon (Gupta 1992; Talwani 1997a, b; Tomic et al. 2009).Triggering of earthquakes by artificial water reservoirs was observed for the first time at Lake Mead, USA (Carder 1945; Gupta 2002). ...Here we use numerical models of the physical process to quantitatively assess the relation between induced seismicity and fluid injection/extraction.

Unlike some other regions, where induced seismicity was triggered in response to higher injection rates, the Raton Basin's frequency-magnitude and spatiotemporal statistics are not distinguishable from tectonic seismicity. The similarity suggests that seismicity in the Raton Basin is predominantly releasing tectonic stress.

The injection-linked seismicity near Jones occurs up to 35 km away from the disposal wells, much further than previously considered in existing criteria for induced seismicity . Modern, very high-rate injection wells can therefore affect regional seismicity and increase seismic hazard.Induced seismicity can be of serious public concern and is capable of leading to a failed project purely due to societal pressure.

This requires a thorough understanding of conditions under which ...The fault reactivation and induced seismicity that are induced by fluid injection are more likely to occur and more serious than that induced by fluid production. Because the fluid injection can cause pressure buildup, reducing effective stresses, which may lead to shear failure eventually, occur and induce seismic events (Vilarrasa et al. …

The question we pose for induced seismicity is whether the largest observed magnitudes are consistent with the sampling statistics of the Gutenberg-Richter MFD, given the total number of induced earthquakes at each site.

A correspondence between the presence of thick sedimentary cover and reduced induced seismicity appears to occur elsewhere in the U.S. Both the Michigan basin and the Williston basin of western North Dakota are sites of significant injection activity but do not show corresponding increases in seismicity [Weingarten et al., 2015].

To deal with this issue, a best-practice framework is needed for the site investigations.
