What is induced seismicity.

A physics-based numerical approach is used to characterize earthquake ground motion due to induced seismicity in the Groningen gas field and to improve empirical ground motion models for seismic hazard and risk assessment. To this end, a large-scale (20 km × 20 km) ...A recent publication by Cesca et al. 1 reanalyzes and expands seismic data to identify hypocenters of observed seismicity induced by the Castor Underground Gas Storage (UGS) operations. Their ...However, more recently induced seismicity has also been tied to hydraulic fracturing both in the Horn River Basin of NE British Columbia [BCOGC, 2012] and in the Fox Creek area of Alberta [Novakovic et al., 2014]. Clearly, such seismicity is of concern to industry, regulators, and the general public. All of the recent syntheses [CCA, 2014; NRC ...The processes behind injection-induced seismicity are not yet understood well enough to make reliable forecasts of the likely seismic response of the underground to hydraulic stimulation.

The seismically active areas in South Africa are broadly divided into two groups in SABS 0160 (1989), namely those where seismic activity is due to natural seismic events (Zone 1 areas), and those where it is predominantly due to mining activity (Zone 2 areas).

In the context of fluid-induced seismicity, various injection parameters have been shown to affect fault behaviour differently, although existing studies about their effects sometimes show ...

Given the high rate of seismicity in Oklahoma, this means that there are still many earthquakes induced by hydraulic fracturing. The remaining earthquakes are induced by wastewater disposal. The largest earthquake known to be induced by hydraulic fracturing in the United States was a magnitude 4.0 earthquake that occurred in 2018 in Texas.

This analysis is accompanied by a study of a 2015 ruling of the Supreme Court of Oklahoma, Ladra v. New Dominion, LLC.
