Global physics-based database of injection-induced seismicity [PDF]

open access: yesEarth System Science Data, 2023
Fluid injection into geological formations for energy resource development frequently induces (micro)seismicity. Moderate- to large-magnitude induced earthquakes may cause injuries and/or economic loss, with the consequence of jeopardizing the operation ...

A physics-informed optimization workflow to manage injection while constraining induced seismicity: The Oklahoma case

open access: yesFrontiers in Earth Science, 2022
A newly developed modelling framework is presented which specifically focusses on the central Oklahoma case and the high-volume injection of wastewater, which led to a surge of induced seismicity.

Seismic Diffusivity and the Influence of Heterogeneity on Injection‐Induced Seismicity

open access: yesJournal of Geophysical Research: Solid Earth, 2021
Abstract 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 ...

Induced Seismicity Reduces Seismic Hazard? [PDF]

open access: yesGeophysical Research Letters, 2019
AbstractEarthquakes caused by human activities have been observed for decades. Often these are related to industrial activities pumping fluids into deep geologic formations, like with wastewater disposal. The simplest theory connecting these processes to earthquakes is straightforward: injection leads to fluid pressure changes that either reduce the ...

Fluid-induced seismicity: comparison of rate- and state- and critical pressure theory

open access: yesGeothermal Energy, 2017
Induced seismicity as generated by the injection of fluids in a homogeneous, permeable medium with faults with variable proximity to rupture conditions is simulated using the rate- and state-dependent frictional fault theory (RST) of Dieterich (J Geophys

Deep Well Injection Induced Seismicity

open access: yesCivil Engineering Dimension, 2022
Injection of fluid into subsurface geologic strata for geothermal energy, oil production, and waste disposal has been linked to induced seismic activity in the United States as well as in several other countries.

Earthquake Nucleation Characteristics Revealed by Seismicity Response to Seasonal Stress Variations Induced by Gas Production at Groningen

open access: yesGeophysical Research Letters, 2023
Deterministic earthquake prediction remains elusive, but time‐dependent probabilistic seismicity forecasting seems within reach thanks to the development of physics‐based models relating seismicity to stress changes. Difficulties include constraining the

A Probabilistic Approach to Injection‐Induced Seismicity Assessment in the Presence and Absence of Flow Boundaries

open access: yesGeophysical Research Letters, 2018
Induced seismicity models that do not account for the effects of flow boundary conditions and uncertainty in initial stresses on the seismicity rate fail to predict the seismicity observed in real‐world injection sites.

Regional variations in the diffusion of triggered seismicity [PDF]

open access: yes, 2005
We determine the spatiotemporal characteristics of interearthquake triggering in the International Seismological Centre catalogue on regional and global scales. We pose a null hypothesis of spatially clustered, temporally random seismicity, and determine
