... in aftershock sequences (Field et al., 2017; Nandan, Ouillon, & Sornette, 2019; Nichols & Schoenberg, 2014; Spassiani & Sebastiani, 2016). Specifically, contemporary forecasting approaches typically utilize the epidemic-type aftershock sequence (ETAS) methodology for simulating seismicity...

... ABSTRACT An understanding of fracture slip susceptibility in geothermal reservoirs is central to the control of fluid injection induced seismicity. To investigate the role of regional fracture systems on induced seismicity, a coupled thermo-hydro-mechanical (THM) model containing fracture...

... ABSTRACT Seismicity can be induced by rock failures or slips along geologic structures around mine workings. Depending on their intensity and proximity to the working area, seismic events may raise safety concerns in underground mining operations. However, the geological and mining parameters...

... will be of paramount importance to reach the world net-zero emissions by 2050. Amongst all the known phenomena related to fluid injection, fault destabilization is one of the main effects to be evaluated with a geomechanical study for the reservoir exploitation. In fact, fault reactivation with induced seismicity has...

... ABSTRACT The Coulomb failure stress (CFS) criterion based on the Mohr-Coulomb friction theory is commonly used to explain physical mechanisms governing injection-induced seismicity. While the CFS criterion can evaluate the onset of fault reactivation caused by fluid perturbations, it cannot...

... seismicity. Numerical modeling of fault reactivation is challenging, while the specific details of induced stresses and fault slip in reservoirs with displaced (i.e. non-zero offset) faults may cause additional challenges depending on the type of numerical formulation employed. To facilitate the systematic...

... ABSTRACT Underground mines are going deeper worldwide with increasing production of mineral resources and decreasing ore grade, and this fact is creating challenging conditions. This fact makes the research into mine seismicity problem paramount. This manuscript focuses on the study of seismic...

... ABSTRACT As part of the development of Induced Seismicity Mitigation Plans (ISMPs) for four proposed enhanced geothermal system sites in Nevada and Oregon, we are evaluating the potential for induced and triggered seismicity and the associated seismic hazard and risk at each site in line...

... ABSTRACT Fracture caging limits hydraulic fracture growth and the activation of faults during high-rate high-pressure fluid injection using pre-drilled boundary wells around the injection well. If successful, this approach could offer a means to limit injection induced seismic magnitudes...

... as they damage excavations, mining equipment and infrastructures, delay production and cause injuries or even deaths of mining personnel. We analyzed the source mechanisms of large mining-related seismic events (M L 1.0 − 2.5) that caused damage to stopes in Siphumelele Platinum Mine. This study attempts...

The resulting TLM data are the foundation for monitoring the temporal changes in fracture characteristics. Furthermore, as new microseismic data...

... ABSTRACT: During the failure of geomaterials, quasi-static (aseismic) and dynamic (seismic) deformation have been observed in laboratory and field experiences. The measurement of both is required for in-depth understanding into the progressive failure of rocks, and to reduce the risk...

... ABSTRACT: Laboratory experimental tests can provide inspirational information for geologists and/or geophysicists to understand field-scale phenomena and processes. Field-scale anthropogenic seismicity catalogs are usually dominated by swarm-like features, while the natural seismicity...

... ABSTRACT: This paper investigates a seismicity sequence that occurred near Stanton, TX between December 2020 and February 2021 with event magnitudes peaking at 4.2. The historically aseismic area has been undergoing shallow salt water disposal (SWD) since the early 1980s, and deep SWD...
