… data to conditions typical of earthquake nucleation depths (7–15 km). It seems that faults
are lubricated during earthquakes, irrespective of the fault rock composition and of the specific …

… in the fault exposures. Both field and experimental data coherently indicate melt lubrication
and low fault strength during earthquakes. Assuming that most frictional work during faulting …

… f during the experiments, we favor the former interpretation based on the following observations:
(1) the attainment of two steady states was never observed during … weakening during the …

… the fault dynamics in light of a fault lubrication mechanism using near-field seismograms and
a detailed rupture model. The fault … following the Reynolds lubrication equation. When the …

… develops during slip lubricates and weakens the fault, … lubricate the fault. We developed a
rotary apparatus specifically designed to simulate earthquake weakening on a laboratory fault …

… or fault area lubricated … during an earthquake. In this study we develop a theory to quantitatively
predict the observable effects of coseismic lubrication by a viscous fluid in a confined fault…

… friction during earthquake slip in the presence of fluids 7,8 . However, up to date, the possible
triggering of EHD in natural faults … For sake of simplicity, tectonic faults can be described at …

… in fault lubrication are still not fully understood. In particular, there is no quantitative model
for fault lubrication during earthquake slip 4 in fine-grained granular material (fault gouges) …
