Research Interests

MaroneŇs recent research has focused on earthquake physics, friction, and geomechanics.  Recent themes have included: 1) slow earthquakes and the spectrum of tectonic fault slip behaviors, 2) rate-state friction mechanics, fault healing and the application of laboratory derived friction constitutive laws to faulting, 3) rock-fluid interaction, reservoir properties, and poromechanics of rock deformation, 4) the role of dynamic stressing in frictional instability, 5) granular mechanics and the effect of particle properties on friction and jamming, 6) the role of shear fabric and clay mineralogy on the frictional strength and constitutive properties of fault rocks, 7) the strength and rheology of fault rocks in nature, with particular focus on samples recovered in scientific drilling.
