• The physics of earthquakes (2001, background): “If a fault zone is narrow and slightly rough, and if the material in the fault zone behaves as a viscous fluid, it is also possible that elastohydrodynamic lubrication plays an important role in reducing friction for large events (Brodsky and Kanamori 2001).”
• Earthquake source scaling and self-similarity estimation by stacking P and S spectra (2004, methodology): “We allowed the values of n to vary while using g = 1 as well as g = 2; that is, we experimented with both the Brune [1970] and Boatwright [1980] models, allowing the falloff term to vary as well as corner frequency and relative seismic”
• A thermal pressurization model for the spontaneous dynamic rupture propagation on a three‐dimensional fault: 1. Methodological approach (2006, background): “boundary lubrication regime and we do not enter in the hydrodynamic lubrication range [Brodsky and Kanamori, 2001].”
• Frictional melt and seismic slip (2008, unknown): “The contribution of hydrodynamic pressure [ Brodsky and Kanamori, 2001 ] at high slip rates could be accounted for by adding a term to sn resulting in”
• Heating and weakening of faults during earthquake slip (2006, background): “Melts, if sufficiently hot, have a low viscosity and may lubricate faults reducing dynamic friction [ Sibson , 1975; Spray , 1993; Brodsky and Kanamori , 2001].”
• Earthquake ruptures with thermal weakening and the operation of major faults at low overall stress levels (2009, background): “These include elastohydrodynamic lubrication (due to pressure gradients established by viscous shear of fault zone fluids or a melt layer trapped between the walls of the fault) [Brodsky and Kanamori, 2001] and silica gel formation [Goldsby and Tullis, 2002; Di Toro et al., 2004].”
• Slip‐weakening behavior during the propagation of dynamic ruptures obeying rate‐ and state‐dependent friction laws (2003, background): “Moreover, other physical processes can contribute to the weakening mechanisms, such as thermal-weakening [Sleep, 1997], fluid pressurization [Andrews, 2002] or mechanical lubrication [Brodsky and Kanamori, 2001].”
