Geolunch
Geolunchs are informal seminars that takes place on friday (12h30-13h30) in room 203 of the La Doua lab.
We talk about planetology, seismology, tectonics, and so on !

Friday 24th of May : Valérie Vidal (LP-ENS) "Triggering large events with small vibrations in granular and solid friction"
Frictional weakening by vibrations was first invoked in the 70's to explain unusual fault slips and earthquakes, low viscosity during the collapse of impact craters or the extraordinary mobility of sturzstroms, peculiar rock avalanches which travels large horizontal distances. This mechanism was further invoked to explain the remote triggering of earthquakes or abnormally large landslides or pyroclastic flows runout. How can endogenous noise or external mechanical disturbances drastically affect the frictional properties? We investigated experimentally the influence of external mechanical waves on both granular and solid friction. When the system is statically loaded, the typical acceleration of the vibrations which trigger large slip events is orders of magnitude smaller than the gravitational acceleration. These results may be relevant to understand dynamic earthquake triggering by small ground perturbations.
