The role of thermal pressurization and dilatancy in controlling the rate of fault slip
Geophysical observations have shown that transient slow slip events, with average slip speeds v on the order of 10−8 to 10−7 m/s, occur in some subduction zones. These slip events occur on the same faults but at greater depth than large earthquakes (with slip speeds of order ∼ 1 m/s). We explore the hypothesis that whether slip is slow or fast depends on the competition between dilatancy, which...
متن کاملHarvard University -- Solid Earth Physics Seminar Thermal pressurization of pore fluid - mechanism for seismic and aseismic self-healing fault slip
There are several lines of evidence that suggest that thermal pressurization (TP) of pore fluid within a low-permeability fault core may play the key role in the development of earthquake slip. To elucidate effects of TP on spontaneous fault slip, I consider solutions for a steadily propagating slip pulse on a fault with a constant sliding friction, the level of which may reflect other thermall...
متن کاملOn the effective stress law for rock-on-rock frictional sliding, and fault slip triggered by means of fluid injection
Fluid injection into rocks is increasingly used for energy extraction and for fluid wastes disposal, and can trigger/induce small- to medium-scale seismicity. Fluctuations in pore fluid pressure may also be associated with natural seismicity. The energy release in anthropogenically induced seismicity is sensitive to amount and pressure of fluid injected, through the way that seismic moment rele...
متن کاملConstraining fault constitutive behavior with slip and stress heterogeneity
[1] We study how enforcing self-consistency in the statistical properties of the preshear and postshear stress on a fault can be used to constrain fault constitutive behavior beyond that required to produce a desired spatial and temporal evolution of slip in a single event. We explore features of rupture dynamics that (1) lead to slip heterogeneity in earthquake ruptures and (2) maintain these ...
متن کاملUsing IRSL to determine the slip rate of the Doruneh fault in Khalilabad
Introduction The left lateral Doruneh Fault System (DFS), is one of the longest, and most prominent, strike-slip faults in Iran, extending from the eastern border of Iran to the central Dasht-e-Kavir with a curved geometry. DFS is the response of the convergence between the Arabian and Eurasian plates in the regional tectonic map. Regarding to scaling relationships this fault with length of ...
