Induced seismicity

We investigate the spatiotemporal evolution of ground motion caused by reservoir-induced seismicity at the Pertusillo artificial lake in southern Italy. The area has a strong seismogenic potential, having been affected in the past by the 1857, Mw 7.0 Basilicata earthquake. We consider ∼1,000 microearthquakes that occurred from 2001 to 2018 and were recorded by a local network of nine seismic ...

About 60 shocks were registered in about 15 days and on the night of October 9, 1963, 350 million cubic metres of rock broke off Mt. Toc and plunged into the reservoir. A huge wave 230-metre high ...If induced seismicity interferes with the use or enjoyment of another's land, then the inducing activity may be a legal nuisance, even if the seismicity causes little physical damage.

Criteria are established to assist in regulating well operations so as to minimize the seismic hazard associated with deep well fluid injectionWith 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 ...This study statistically evaluated the characteristics of induced earthquakes by geothermal power plants (GPPs) and generated a probabilistic model for simulating stochastic seismic events. Four well-known power plant zones were selected worldwide from the United States, Germany, France, and New Zealand. The operational condition information, as well as the corresponding earthquake catalogs ...The fluid pressure then migrates from east to west through faults in the basement as evident from the timing and location of the induced seismicity. Finally, the fluid pressure may migrate vertically upward along the west sequence fault, as hinted by the seismicity pattern (Birdsell et al., 2015; Haagenson & Rajaram, 2020).

Yet, little is known about how the public perceives induced seismicity, whether they support ...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).The spatiotemporal patterns of injection-induced seismicity (IIS) are commonly interpreted with the concept of a triggering front, which propagates in a diffusion-like manner with an associated diffusivity parameter. Here, we refer to this diffusivity as the "seismic diffusivity." Several previous studies implicitly assume that seismic ...

P Jauhari in his paper "Reservoir-Induced Seismicity (RIS)" said "The most widely accepted explanation of how dams cause earthquakes is related to the extra water pressure created in the micro-cracks and fissures in the ground under and near a reservoir. When the pressure of the water in the rocks increases, it acts to lubricate faults ...Induced seismicity is a limiting factor for the development of Enhanced Geothermal Systems (EGS). Its causal mechanisms are not fully understood, especially those of post-injection seismicity.The USGS has focused some research on the seismicity in Oklahoma and determined that the main seismic hazard within the state is the disposal of wastewater from the oil and gas industry by deep injection, though some smaller quakes (magnitude 0.6 to 2.9) have been shown to correlate directly to fracking. A 50% increase in earthquake rate has ...To reduce the probability of future large earthquakes, traffic light systems (TLSs) define appropriate reactions to observed induced seismicity depending on each event's range of local earthquake magnitude (ML). The impact of velocity uncertainties and station site effects may be greater than a whole magnitude unit of ML, which can make the difference between a decision to continue ("green ...

Mining-induced seismicity has been investigated for a long time in many countries with mining ...Induced seismicity is often expected to follow a clear pattern, yet pressure perturbations in the subsurface are controlled by local geology, which varies widely. The far-reaching effects of fluid pressure in sedimentary basins of varying depth, lithology, and structure, combined with low triggering thresholds, create variety in the temporal ...The induced seismicity is outside of the inferred diffusivity envelopes, which suggests a different causal mechanism. Several faults appear to be solely induced seismicity and a result of flow through natural fractures or pressure perturbations.
