Principal Slip Zones in Nature and Experiments and Their Role in the Earthquake Cycle
Earthquakes generally do not occur in intact rocks but rather within extremely narrow (≤10 cm) principal slip zones found along fault zones. These slip zones are relatively weaker than the surrounding wall rocks suggesting they play an important through the earthquake cycle. This thesis explores …

Glacial isostatic adjustment and relative sea level change over the last earthquake cycle in upper Cook Inlet, Alaska, USA
… and tectonic deformation over the last great earthquake cycle in south central Alaska. Reconstructions of relative sea level change over the last 900 years, based upon extensive lithological, biostratigraphical and chronological investigations of salt marsh sequences in upper Cook Inlet, …

Effects of fault failure parameterization and bulk rheology on earthquake rupture
… associated with material failure affect earthquake rupture nucleation and propagation. These processes are frictional sliding along faults of different roughness, fracturing of the intact rock sections connecting the preexisting planes of weakness (fault step overs) or cemented fault …

INFERRED RHEOLOGY AND UPPER MANTLE CONDITIONS OF WESTERN NEVADA AND SOUTHERN CALIFORNIA-NORTHWEST MEXICO
… processes such as mantle convection, the earthquake cycle, and plate tectonics. This study uses tectonic (postseismic) and non-tectonic (lake unloading) events that have induced differential stress changes within the crust and mantle, which in turn, create surface deformation. The …

The evolution of lithospheric deformation and crustal structure from continental margins to oceanic spreading centers
… that over time scales longer than a typical earthquake cycle transform faults behave as zones of significant weakness.

Present-day and late Quaternary crustal deformation along the southern Dead Sea Fault System, Jordan
Theoretical models of the earthquake cycle predict that crustal rheology may lead to differences between short-term crustal deformation rates (decadal time scales) and long-term fault slip rates (Holocene to late Pleistocene time scales). This study investigates fault kinematics along the southern …

Kinematic models of interseismic deformation in Southern California
… dependent surface deformation though the seismic cycle. We extend a classic theory from periodic to temporally clustered earthquakes by superposing several out of phase earthquake cycles. This new model displays a much wider range of behaviors than does the periodic earthquake cycle model and …

Characteristics of active deformation, fault interaction, and earthquake triggering in a rapidly-deforming complex normal fault network (south-west Türkiye)
Despite often being overshadowed by disastrous earthquakes on subduction zones and continental transform faults, normal faulting earthquakes frequently cause severe destruction and casualties. Understanding earthquake occurrence and determining those faults most at risk of rupturing in destructive …

Laboratory analysis of restrenghtening on simulated faults
… that stress drop increases with the logarithm of earthquake recurrence interval (1-5 MPa per decade time). If stress drop is taken as a proxy for fault strength, then the data suggest that faults restrengthen during the quiescent period of the earthquake cycle. Seismic surveys across natural …

A new hybrid numerical scheme for simulating fault ruptures with near fault bulk inhomogeneities
"The Finite Difference (FD) and the Boundary Integral (BI) Method have been used extensively to model spontaneously propagating shear cracks in a variety of engineering and geophysical applications. While FD has a large computational cost as it requires the discretization of the whole volume of …

Quantifying forearc deformation patterns using coastal geomorphic markers
… are repeatedly breached by giant megathrust earthquakes. The coastal relief along tectonically active realms is shaped by the effect of sea-level variations and heterogeneous patterns of permanent tectonic deformation, which are accumulated through several cycles of megathrust earthquakes. …
