Coseismic fault lubrication by viscous deformation (2021)
Journal Article
Pozzi, G., De Paola, N., Nielsen, S., Holdsworth, R., Tesei, T., Thieme, M., & Demouchy, S. (2021). Coseismic fault lubrication by viscous deformation. Nature Geoscience, 14(6), 437-442. https://doi.org/10.1038/s41561-021-00747-8

Despite the hazard posed by earthquakes, we still lack fundamental understanding of the processes that control fault lubrication behind a propagating rupture front and enhance ground acceleration. Laboratory experiments show that fault materials dram... Read More about Coseismic fault lubrication by viscous deformation.

Thermal weakening friction during seismic slip experiments and models with heat sources and sinks (2021)
Journal Article
Nielsen, S., Spagnuolo, E., Violay, M., & Di Toro, G. (2021). Thermal weakening friction during seismic slip experiments and models with heat sources and sinks. Journal of Geophysical Research. Solid Earth, 126(5), Article e2020JB020652. https://doi.org/10.1029/2020jb020652

Experiments that systematically explore rock friction under crustal earthquake conditions reveal that faults undergo abrupt dynamic weakening. Processes related to heating and weakening of fault surfaces have been invoked to explain pronounced veloci...

Scaling Seismic Fault Thickness From the Laboratory to the Field (2021)
Journal Article
Ferrand, T. P., Nielsen, S., Labrousse, L., & Schubnel, A. (2021). Scaling Seismic Fault Thickness From the Laboratory to the Field. Journal of Geophysical Research. Solid Earth, 126(3), Article e2020JB020694. https://doi.org/10.1029/2020jb020694

Pseudotachylytes originate from the solidification of frictional melt, which transiently forms and lubricates the fault plane during an earthquake. Here, we observe how the pseudotachylyte thickness a scales with the relative displacement D both at t... Read More about Scaling Seismic Fault Thickness From the Laboratory to the Field.
