estimates of earthquake source parameters, such as stress drop and radiated seismic …

Parallel dynamics of slow slips and fluid-induced seismic swarms

P Danré, L De Barros, F Cappa, L Passarelli - Nature Communications, 2024 - nature.com
Earthquake swarms may be driven by fluids, through hydraulic injections or natural fluid
circulation, but also by slow and aseismic slip transients. Understanding the driving factors …

Migration of fluid‐induced seismicity reveals the seismogenic state of faults

L De Barros, N Wynants‐Morel… - … Research: Solid Earth, 2021 - Wiley Online Library
Seismic swarms, in natural contexts or induced by anthropogenic fluid injections, commonly
show migrations of earthquake hypocenters. Classically, such migrations are interpreted as …

Dual seismic migration velocities in seismic swarms

P Dublanchet, L De Barros - Geophysical Research Letters, 2021 - Wiley Online Library
Fluid‐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 …

Misconception of waveform similarity in the identification of repeating earthquakes

D Gao, H Kao, B Wang - Geophysical Research Letters, 2021 - Wiley Online Library
Identification of repeating earthquakes (repeaters) usually depends on waveform similarity
expressed as the corresponding cross‐correlation coefficient (CC) above a prescribed …

Induced seismicity controlled by injected hydraulic energy: The case study of the EGS Soultz‐sous‐Forêts site

K Drif, O Lengliné, J Kinscher… - Journal of Geophysical …, 2024 - Wiley Online Library

Identification of repeating earthquakes: controversy and rectification

D Gao, H Kao, J Liu - Seismological Research Letters, 2023 - pubs.geoscienceworld.org
Repeating earthquakes (repeaters) are events that recurrently rupture the same fault patch
with nearly identical magnitudes. Although repeaters have been widely studied and utilized …

From seismic quiescence to surged activity after decades of wastewater disposal: A case study in central‐west Alberta, Canada

H Yu, H Kao, R Visser, B Wang - Geophysical Research Letters, 2021 - Wiley Online Library

The evolution of fluid injection‐induced seismicity, generally characterized through the
number of events or their seismic moment, depends on, among other factors, the injected …

Permeability anisotropy in sandstones from the Soultz-sous-Forêts geothermal reservoir (France): implications for large-scale fluid flow modelling

M Goupil, MJ Heap, P Baud - Geothermal Energy, 2022 - Springer
The successful exploitation of geothermal reservoirs relies upon the understanding of fluid
circulation in the subsurface. However, large-scale fluid flow modelling often assumes that …
