In Stathas and Stefanou (2022) we presented the frictional response of a bounded fault gouge under large coseismic slip. We did so by taking into account the evolution of the Principal Slip Zone (PSZ) thickness using a Cosserat micromorphic continuum model for the description of the fault’s mechanical response. The numerical results obtained differ significantly from those predicted by the established model of thermal pressurization during slip on a mathematical plane (see Mase and Smith (1987…

Thermal pressurization and onset of melting in fault zones

[1] We examine how frictional heating drives the evolution of temperature, strength, and fracture energy during earthquake slip. For small slip distances, heat and pore fluid are unable to escape the

Effects of frictional heating on the thermal, hydrologic, and mechanical response of a fault

The mechanical response of a fault zone during an earthquake may be controlled by the diffusion of excess heat and fluid pressures generated by frictional heating. In this study we formulate a fault

Thermal decomposition of carbonates in fault zones: Slip-weakening and temperature-limiting effects

[1] During an earthquake, the heat generated by fault friction may be large enough to activate the devolatilization of minerals forming the fault rocks. In this paper, we model the mechanical effects

Frictional heating and pore pressure rise due to a fault slip

Summary. Accurate estimation of frictional stress is crucial to determining the bounds of pre- and post-earthquake states of stress. A long-term average value of 10 MPa, deduced from heat flow data

Thermal Pressurization Weakening in Laboratory Experiments

Thermal pressurization (TP) is expected to be a dominant frictional weakening mechanism during earthquakes. However, most of our understanding of TP relies on theoretical studies. Our experimental

Stability analysis of undrained adiabatic shearing of a rock layer with Cosserat microstructure

Stability of undrained shearing in a classical Cauchy continuum has been first analyzed by Rice (J Geophys Res 80(11):1531–1536, 1975) who showed that instability occurs when the underlying drained

Pore-fluid pressures and frictional heating on a fault surface

This study considers the effects of heat transfer and fluid flow on the thernal, hydrologic, and mechanical response of a fault surface during seismic failure. Numerical modeling techniques are used

The Effects of Flash‐Weakening and Damage on the Evolution of Fault Strength and Temperature

The effects of fluid pressurization in altering the fault strength and limiting the temperature rise during earthquake slip are modeled for the case of a thin, but finite, shear zone, with
