Investigations and new insights on earthquake mechanics from fault slip experiments

L Dong, Q Luo - Earth-Science Reviews, 2022 - Elsevier
Earthquakes occur mainly on active faults. Fault slip is closely related to seismicity and is
thus widely discussed in Geosciences, Seismology, and Engineering. Slip experiment is a …

Stabilization of fault slip by fluid injection in the laboratory and in situ

F Cappa, MM Scuderi, C Collettini, Y Guglielmi… - Science …, 2019 - science.org
Faults can slip seismically or aseismically depending on their hydromechanical properties,
which can be measured in the laboratory. Here, we demonstrate that fault slip induced by …

F Cappa, Y Guglielmi, C Nussbaum, L De Barros… - Nature …, 2022 - nature.com
Understanding the response of faults to the injection of high-pressure fluids is important for
several subsurface applications, for example, geologic carbon sequestration or energy …

[HTML][HTML] A shift from drought to extreme rainfall drives a stable landslide to catastrophic failure

AL Handwerger, MH Huang, EJ Fielding, AM Booth… - Scientific reports, 2019 - nature.com
The addition of water on or below the earth's surface generates changes in stress that can
trigger both stable and unstable sliding of landslides and faults. While these sliding …
