Tidal modulation of slow slip in Cascadia [PDF]

Journal of Geophysical Research, 2010
Several studies have shown that the seismic tremor in episodic tremor and slip is tidally modulated, suggesting a sensitivity to the rather small tidal stresses. We address whether the slip rate in slow slip events is also tidally modulated by examining data from six borehole strainmeters in northwest Washington and southern Vancouver Island.

Slow slip and the transition from fast to slow fronts in the rupture of frictional interfaces. [PDF]

Proc Natl Acad Sci U S A, 2014
Significance Relative motion between solids in frictional contact is known to start progressively, with a slipping zone growing along the interface. The propagation of the front separating the stuck and slipping zones is usually very fast, but it can also slow down considerably. This transition is not yet understood. Using a multiscale model,

The slow slip of viscous faults [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractWe examine a simple mechanism for the spatiotemporal evolution of transient, slow slip. We consider the problem of slip on a fault that lies within an elastic continuum and whose strength is proportional to sliding rate. This rate dependence may correspond to a viscously deforming shear zone or the linearization of a nonlinear, rate‐dependent ...

Slow slip events are regular earthquakes [PDF]

, 2021
Abstract Slow slip events usually occur downdip of seismogenic zones in subduction megathrusts and crustal faults, with rupture speeds much slower than earthquakes. The empirical moment-duration scaling relation can help constrain the physical mechanism of slow slip events, yet it is still debated whether this scaling is linear or cubic and a ...

Slow slip source characterized by lithological and geometric heterogeneity. [PDF]

Sci Adv, 2020
Slow slip events on subduction megathrusts are linked to subduction of rough crust and heterogeneous fault rock properties.

Slow slip modulates low-frequency seismicity on the Parkfield segment of the San Andreas Fault [PDF]

Nature Communications
Understanding how slow slip events (SSEs) influence fault behavior is essential for characterizing the fault slip spectrum and its role in earthquake generation.

Is There Slow Slip on the Wasatch Fault?

, 2009
To accurately determine the earthquake hazard posed by a fault, we need to understand both strain accumulation and release along the fault. Strain accumulates during aseismic periods but it is released during fault slip events that can be either seismic or aseismic.

Global subduction slow slip events and associated earthquakes. [PDF]

Sci Adv
Three decades of geodetic monitoring have established slow slip events (SSEs) as a common mode of fault slip, sometimes linked with earthquake swarms and in a few cases escalating to major seismic events. However, the connection between SSEs and earthquake hazard has been difficult to quantify and contextualize beyond regional studies.

Data assimilation for fault slip monitoring and short-term prediction of spatio-temporal evolution of slow slip events: application to the 2010 long-term slow slip event in the Bungo Channel, Japan

Earth, Planets and Space
Monitoring and predicting fault slip behaviors in subduction zones is essential for understanding earthquake cycles and assessing future earthquake potential. We developed a data assimilation method for fault slip monitoring and the short-term prediction

The Ocean's Impact on Slow Slip Events

Geophysical Research Letters, 2020
We test the hypothesis that ocean seafloor pressures impart stresses that alter the initiation or termination of transient slow slip events (SSEs) on shallow submarine and near‐coastal faults, using simulated seafloor pressures and a new catalog of SSEs ...
