Pore-pressure diffusion, enhanced by poroelastic stresses, controls induced seismicity in Oklahoma
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance We develop a physics-based earthquake-forecasting model for evaluating seismic hazard due to fluid injection, considering both pore pressure and poroelastic stresses.

Induced seismicity in geologic carbon storage
Solid Earth, 2019 . Geologic carbon storage, as well as other geo-energy applications, such as geothermal energy, seasonal natural gas storage and subsurface energy storage imply fluid injection and/or extraction that causes changes in rock stress field and may induce ...

Seismicity and Principal Seismic Effects [PDF]
Geophysical Journal International, 1970 Summary A statistical method is given for estimating the total effect of earthquakes over a given period. The effect may be measured by return-time, shaking or damage, and may be exerted at a point (e.g. building), on a linear object (e.g. road), or on an area. For each type of effect there are given formulae for the statistical distribution,

Heterogeneous Fracture Slip and Aseismic‐Seismic Transition in a Triaxial Injection Test
Geophysical Research Letters, 2020 Fault/fracture slip and seismicity caused by fluid injection are of major interest to subsurface science and engineering. However, some fundamental aspects of the temporal and spatial evolutions of induced seismicity remain unresolved.

Dual Seismic Migration Velocities in Seismic Swarms
Geophysical Research Letters, 2021 AbstractFluid‐induced earthquake sequences generally appear as expanding swarms activating a particular fault. The recent analysis of a swarm in the Corinth rift has revealed a dual migration pattern, with a global slow expansion (m day−1) and episodes of rapid migration (km day−1).

Anomalous stress diffusion in earthquake triggering: Correlation length, time dependence, and directionality [PDF]
, 2003 It has been recently suggested that moderate and large earthquakes can be triggered by similarly sized events at very long range. Here we study the main characteristics of earthquake triggering by determining its correlation length, time dependence, and ...

Induced Seismicity Reduces Seismic Hazard? [PDF]
Geophysical 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 ...
