Dynamic weakening during earthquakes controlled by fluid thermodynamics

M Acosta, FX Passelègue, A Schubnel… - Nature …, 2018 - nature.com
Earthquakes result from weakening of faults (transient decrease in friction) during co-seismic
slip. Dry faults weaken due to degradation of fault asperities by frictional heating (eg flash …

Mechanical behaviour of fluid-lubricated faults

C Cornelio, E Spagnuolo, G Di Toro, S Nielsen… - Nature …, 2019 - nature.com
Fluids are pervasive in fault zones cutting the Earth's crust; however, the effect of fluid
viscosity on fault mechanics is mainly conjectured by theoretical models. We present friction …
