... 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...

... ABSTRACT: Seismicity induced by injection of energy depleted geothermal fluid, as well as field injectivity, has been observed to be inversely correlated with the temperature of re-injected fluids at the Hellisheiöi geothermal field, Iceland. Using the Hellisheiöi field injection data...

... ABSTRACT: An important consideration for managing induced seismicity is the characterization of seismicity following operational changes made in an attempt to mitigate seismicity. When operational changes are made to control seismicity, ongoing activity associated with earlier activated...

... ABSTRACT: Seismic events may occur naturally or unnaturally as a result of human activity. The focus of this research is on seismicity caused by human activities in underground mines. Despite significant technological advances in the mining industry, the phenomenon of rockburst and its...

... 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...

... below the surface with plans to reach 3.4 km. The LaRonde mine has been dealing with induced seismicity daily since 2003. The seismic activity can exceed M Richter 2, and the pro-active management of seismic risk is a key element to operate this mine at that depth and under these seismically active...

... ABSTRACT: Injecting CO 2 into a deep geological formation (i.e., geological carbon storage, GCS) can induce earthquakes along preexisting faults in the earth’s upper crust. Seismic survey and regional geo-structure analysis are typically employed to map the faults prone to earthquakes prior...

... measurements and observations to understand these important processes, we study laboratory acoustic emissions in combination with numerical models to shed light on the physics governing seismicity. A dry sample of Berea sandstone was tested to failure under a confining pressure of 40 MPa in a triaxial machine...

... ABSTRACT: Strength of the materials involved in the fluid injection is usually well assessed and injection pressure is maintained below the critical value to avoid induced seismicity. However, a microcracking activity could be triggered at stress levels well below the peak strength and could...

... ABSTRACT: Geological hydrogen storage is a promising technique to seasonally store surplus renewable energy at the large scale. Depleted gas reservoirs are currently being considered as potential storage sites for hydrogen. Induced seismicity is a key aspect of the sustainability...

... ABSTRACT: EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) integrates, within the framework of the European Plate Observing System (EPOS) (www.epos-eu.org), research infrastructures freely open for scientists, engineers, and all others interested in hazards posed by the seismicity...

... geometry and geomechanical status over time without requiring additional data acquisition or monitoring tools. 41 years of raw waveform data from multiple generations of seismic networks from the Geysers geothermal field were amalgamated to generate a catalog of 9,601 stable full-waveform MTI solutions...

... 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...

... conditions, most shale gouges are frictionally strong and exhibit velocity-strengthening response, indicative of fault aseismic slip, except for ~5% of shale gouges showing velocity-weakening behavior and potentially promoting seismic slip. Considering the small proportion of unstable shale gouges...

..., as well as the preliminary results obtained from the capture of geological, geomechanical and operational data. Finally, the seismic response of the rock mass to mining is compared with and without the application of this technique. 1. INTRODUCTION 1.5x105 Joule, in PK 4.600 Tunnel in connection zone...

... ABSTRACT: Efforts to quantify induced-seismicity risk and to develop mitigation strategies are hampered by a dearth of numerical schemes that can accommodate realistic Earth models while capturing the full spectrum of applicable physics. Here we present a new approach to modelling induced...

... ABSTRACT: Understanding the physical mechanisms controlling fluid-injection-induced seismicity in a gouge-filled fault is crucial in the assessment and mitigation of induced seismicity, especially in the context of subsurface technologies like wastewater disposal, hydraulic fracturing, oil...

... ABSTRACT: On 30 November 2018, a felt (ML 4.5) seismic event occurred near Fort St. John, British Columbia, that has been attributed to ongoing hydraulic fracturing operations in the area. Over a 2 week period (3 days before, and 10 days after the mainshock), almost 600 events (M L −0.3 to M...
